In this video we'll explore the world's fastest improving new solar technology, and provide an exclusive peek inside the lab of a team working on this breakthrough material.
Imagine an inexpensive solution of perovskite crystals that can make a photovoltaic cell so thin, that just half a cup of liquid would be enough to power a house. A solar panel so lightweight, that it can be balanced atop a soap bubble. That is known as the holy grail of solar energy. So when will we see perovskite solar panels used for a solar power system for your home? Maybe sooner than you expect.
Currently, only 2% of global electricity comes from solar power. And 90% of that, comes from crystalline silicon-based solar panels, the dominant material technology.
While abundant, silicon has downsides related to efficiency, manufacturing complexity, and pollution that prevent it from being an absolute no brainer. Emerging thin films like perovskites present a bright future. Imagine solar cars like a solar tesla, solar yachts, or a solar plane.
Solar cell technologies can be classified into two categories, wafer-based or thin-film cells. Perovskites are the leading contender in emerging thin films. Topics covered in this video include applications, perovskite crystal structure, working principle of perovskite solar cells, efficiency limits, multi-junction solar cells, shockley-queisser limit, how solar works, solar simulator, band gap, manufacturing, vapor deposition, how solar panels are made, and the future of solar power.

It's nice that he was honest about the main disadvantage, longevity.
They are getting better making them last. Stacking silicon with perovskite is one way. Also wider band or more light sensativite to other wavelengths. Looks very promising
I just got a patent on a new, non-variable clean energy concept. This video talks about some of the down sides of this technology. My concept may solve those issues. Do you know where I can contact them?
Did you notice the part about how they aren't as good as normal cells? LMFAO!
@@bobsmith6544 People keep using "not as good" tech all the time. Like paying far more for maintenance and per mile just because ICE cars are little cheaper to buy and faster to refuel.
These panels could deliver twice as much power as modern panels at far cheaper price, and because they can be lighter than the silicon panels they would also be cheaper to transport and easier to handle so even the most expensive part, the installation, could cost less. At lower price it is also viable to do things like putting panels on the walls or the less sunny side of the roof, so instead of paying $20k for a 10kW system you might get 25kW for $5k, at which price you would likely save money even if the panels had to be replaced every five years.
It all boils down to cost. If its cheap enough, then it will be like getting your house repainted.
In the past few years, traditional silicon panels have gotten down to ~70 cents a watt at retail prices. That's only $7000 for a 10KW installation. if you're a DYIer, you are no longer looking a a $20K+ installation. Inverters are cheap, and if you use forklift deep cycle lead acids, you can build your own "power wall", without subsidizing Elon Musk's lifestyle.
I truly appreciate the honesty in this video presentation. They ask hard questions and point out both the positive and negative attributes of this technology. Over 50 years of R and D with solar and we are still waiting for a significant break through. I do hope that Perovskites prove to be that breakthrough.... The solar cell and the battery still have a lot of improvements to go through before they become a viable, national energy sources.
Especially battery, EVs may run without burning any fuel, but making those batteries are as damaging to the ecosystem as running a regular car for quite some time.
@@wybuchowyukomendant Yep, people should learn to be more efficient rather than asking their tech to bend over backwards for them.
Significant breakthrough? I think that’s called a solar panel, don’t think we had those in the 1800s
i think its cool to think about that probably somewhere in my lifetime we have figured out how to provide plenty of energy to everyone on earth for cheap without destroying the planet. i am 20 btw if you are wondering.
@@mauritshagedorn856 We have plenty already, we need to stop being wasteful, but people need 70" TVs so im not holding my breath.

This was a great video. As someone who is going to college for materials science, it was cool to see the concepts brought up in ways that make it easy for a layperson to understand, and also very cool to see the guy from the company be honest about the downsides to perovskite solar cells.
Materials science is definitely the best major to do some very positive good for the world right now. We'll watch your career with great interest... ☺️
Hey I love that guy you interviewed being straightforward and honest. The big issue is stability and I'd love to find out more about that.
Remember when NASA did our experimentation and invented our new technology with billions invested in various projects, instead of grad students with delusions of grander?
Yeah, I wish this channel went more in depth on the drawbacks instead of only highlighting the pros. Luckily the CEO was transparent and not overly enthusiastic since there are a lot of challenges to getting this tech widely accepted and implemented. I shouldn't have to go to the comment section to learn that the stability issue is that the cells degrade significantly in a couple of days. I shouldn't have to go to Google to learn that viable perovskite cells rely on lead. Also, in the video the film is thin enough where it is tinted and not translucent. How can they achieve >30% efficiency when much of the light is getting through? Are all of the numbers touted in terms of materials needed and efficiency consistent or based on different specifically tailored conditions? This is the kind of video where I am just frustrated that the author went the "research stretching the truth to gain investors" route instead of piggybacking off of the CEO grounding the tech in reality.
@@johnpeters6147 As you astutely note in your comment, this is a marketing video and such things are done to attract venture capital, as depicted in the efficiency discussion. I appreciated the additional comments in your reply.
@@johnpeters6147 The problem with PTF has been durability and deteriorating properties in real world use. This is something that we've been working on for over a decade and while there have been various different solutions, most of them take away from the properties that make PTF useful. Thus, any kind of method of reinforcing PTF makes them heavier, rigid, or more expensive. The lifespan being 5-20 times shorter counters the issue of resources used for production as well. We might get there some day, but PTF has a long way to go as a usable technology for any kind of hype to be built on it yet.
Fantastic presentation on a solar technology I didn't even know existed. I always love hearing about newer and better technology. In my heart I know you'll solve the problems surrounding early degradation. Cheaper more cost effective so what's not to like? Scientists like yourself always amaze me. Thank you for everything you do to make this world a better place to live. Energy costs have a lot to do with making that happen. Know that you're very much appreciated!
I would much rather hear about new and emerging technologies than “our planet is doomed “. Science will eventually ’crack’ nuclear fusion as long as the ‘net zero’ brigade don’t get in the way of progress.
totally agree with you... and making solar power cheaper and more effective is such a goood thing for 3rd world countries and all that... and tbh for everyone because smaller countries wouldnt be so dependent on bigger countries for power
I believe they will figure out what to cover this with and then preserve it for much longer my ideas would be silicone or plastic
Michael. Glad to ser you now watching the technology. Have bern watching and using solar from back in the 60s. Im so tired of the "i know it wont work" crowd. Things get better. Now we have cars tbat can be charged on solar panels. What is wrong eith these people.
invented in Poland, by a woman
I have been pro R and D on solar, but against mass implementation, as we are going too fast before the tech is ready on that scale. This could truly be a game changer. Keep the R and D going.
This is not what I expected for Season 17 bungie...
The most beautiful thing in living long enough is that we see more new things and get the chance to use some of them. Who would have thought of such technology ?
Joel Jean
Scientists and Engineers would have thought of such technology.

Fantastic video, both your enthusiasm and optimism for this new developing technology radiated through the script!
Very well written piece. Twice, so far, he mentioned something I was questioning. This one was when he said the two chips were samples used in the lab. I was thinking when he first talked about them, they seem a lot closer than 10 years away.
This wasn't what i was after when I searched up Solar 3.0, but I'm glad I chose to watch it regardless. Great video!
Crazy to think this tech is less than a month away eh… it’s only gonna last for about a month as well and then we get arc 3.0. Crazy electrical advancements… LMAO
I was searching for a comment like this
PvP Next month is gonna be fun
This is definitely something I hope becomes commercially available soon because I inted to heat my house using Geo-thermal and I'd like Solar Panels (with w/e batteries I can get for energy storage for cold/night time usage) to be what is giving the geo-thermal unit all the energy it needs to operate at 100%. Not needing to burn wood or use oil/propane etc. is a dream of mine but living in NH I worry about how many solar panels I'll need to get so that (even in Winter time) I never have to worry about having enough power to run my geo-thermal unit. I haven't done any research into how much solar panels are going to cost me but, as long as I can afford it, I have no doubt I'll be needing dozens for year round powering/usage.
You will need 3kw for dark evenings and mornings. You would need at least three GTesla Powerwall equivalents.
I really hope solar 3.0 brings two icarus dashes back for pve atleast
He said, "Stability is still a challenge..."
IOW, the perovskites don't last very long, much less than 25 years. They won't be able to be used for rooftop or utility scale solar systems until their "stability" AKA lifetimes can be increased to 25 years.
If perovskites can be made cheap enough, the sheets might be made to be quickly and easily changed when they lose efficiency.
1/15 the cost seems to make up for the more limited lifespan.
Depends on how it gets used, i dont agree that we would need one or another, for long-living installations you could make solar cells like we have now, but for stuff where its a temporary set-up than this would be a massive success. The light weight and cheapness of the cell makes it perfect to be put on stop of cars, it would be a perfect addition to electric cars, and given that most cars are used during the day, i would say that a much much smaller battery could be out into such a car all in order to reduce weight and give a small timespan in order to go through moments of missing sunlight.
This technology would be a godsend in areas where there is a lot of sunlight to begin with.
On top of that, if they manage to scale it up and make it light-weight enough, they could even put it on clothes for induvidual uses, so your smartphones battery timespan wouldnt be the main concern of yours anymore, and a single piece of clothing usually isnt used for over 15 years , so the cell would be a great fit on that as well.
And on many many other consumable goods this technology would be perfect, for example you want to go into the forest and relax but not miss out on the convenience of electrity, you could just bring a big piece of cloth which you span on a open field, than charge your devices via that.
Maybe im a bit to positive on the good aspects of this technology, but i thing that given the trend to having more smart tools surrounding us, this technology would fit right into that market.
So put them in a place where they won't be exposed to the outside elements and be temp controlled. I know that sounds crazy, but I have an idea (and a patent) if you want to know more, let me know.
Other companies have to intentionally bother making products obsolete over time, if this is both cheap and has a decent but not long longevity its not that big of a negative either, specially since there's manual labor involved (it might help sustain the market since more installations over time means more laborers supporting it to get more labor out of it).
Not a fan of planned obsolence but still worth noting I think.
The life of these new panels vs silicon panels, assuming the 15x production saving = 1.66 years. so if the formula lasts 2 years before having to be replaced, that accounts for the cost of a worker to replace the panels, which after the initial install would be a 30-60 minute job of unscrewing one set of panels and screwing in the new set.
Benefit being new formula(s) that might mean longer life and / or more power both of which are of benefit to the user. Loner life = less re-installs, more power = feeding more back to the grid for credit off the power bill.
From past few years, I've been hearing of things that will revolutionize power production. Yet to see even one available commercially.
Because price the existing products is low because of mass production it's really hard for a new product to get into a market. You first need to reach that price point. Very often a new product only succeeds because it has an advantage in an other area so it can be further developed and mass production processes improved.
When all is said and done more is said than done.
@@autohmae or if you’re Tesla, you can out leverage the market with tax incentives and an army of redditors
What an ignorant comment lmao. Technology has exponentially advanced in a handful of generations. Flight, Cars, space probes, wireless communications and antibiotics were all advanced in same 200 year period lmao.
You won't even be able to comprehend the next 50 years.
Graphene is one of them you see in upcoming future.
A common problem with thin film types is that high temperatures cut the lifespan. For the western states silicon crystal holds up best, so far. If only they can come up with a thin film type that will stand up to extremes in temperature.
Graphene could serve as the transparent electrode. Graphene is almost a one-atom-thick superconductor and can be applied using chemical vapor deposition (CVD). CVD is currently the front running process for making graphene.
Even though there may be lifetime limitations for Perovskite solar cells, they are so cheap to make and produce so little pollution, they can be considered disposable.
Disposable? It wouldn't be long till your fish steak tasted of Perovskite.
Great graphene... Worse polluter than plastic. It's like micro glass polluting water.
Can't wait for season 17
Mr. Jean does an excellent job of explaining Swift Solar's approach. I also appreciate his candor on his current priorities for scaling production, his manufacturing and testing methodologies, what the limitations currently are (longevity and environmental ruggedness), the current market applications, and his priorities in broadening its utility by addressing the longevity issues.

The initial video depicting the electron-hole interaction when the P and N-type materials are brought into contact was something you might consider donating to a University for the 1st course of Solid State Device physics. It would also be useful to incorporate the discussion of the Fermi level as part of the discussion to round out the band gap discussion. Good luck in your venture but many practical problems to overcome but your video shows you have a grasp of many such issues.
Outstanding presentation. Super interesting details direct from the company, including their manufacturing process
I am excited to see where this goes and really want to even be able to create one of these items. Seems nice. Very nice. Just need the knowledge of how they work and how to wire them.
I’m currently doing the nabcep Solar course and this information was really helpful
This got me much more interested and educated than severals hours our lessons on perovskites for material science. I was surprised there was no mention of the Lead (Pb) as most issues with perovskites used to be that we didn't know how to do lead-free perovskites crystals. I would have liked to know more about the toxicity of these coatings
you want to know about the toxicity of lead coatings: lead = bad... thats all... despite any any precaution taken or how its engineered it will ALWAYS be a problem
Pb = lawsuits
Can confirm it is highly toxic

So informative and I didn't know there was better technology, instead of the existing solar panels systems.
Thank you for asking all the right questions
I am working with a few groups developing and testing perovskite research cells and mini modules at NREL. There has been a lot of momentum (money) behind this as the new OPV, and efficiencies have shot up quickly. I see some of the newest devices from universities and startups.. there is still a long way to go for stability of these modules and materials
That's interesting work you do. I am a electrician in the great state of Texas and for the past year i have been working for a master electrician installing solar. We do the whole system modules and the solar walls I like the work and I'm really interested in solar. Really looking forward to lighter modules cause carrying them on a roof is a work out.
NREL has an incubator for the R&D of solar and Geo
Would be interesting to see how these are plausible in aero projects. Food for thought
solar 3.0 confirmed for next season lets goooooo
"Stability and Degradation: Perovskite solar cells have demonstrated competitive efficiencies with potential for higher performance, but their stability is quite limited compared with that of leading PV technologies: They don’t stand up well to moisture, oxygen, extended periods of light, or high heat. To increase stability, researchers are studying degradation in both the perovskite materials and the contact layers. Improved cell durability is paramount for the development of commercial perovskite solar products.
Despite significant progress in understanding the stability and degradation of perovskite solar cells, current operational lifetimes are not commercially viable. Mobile markets may tolerate a shorter operational life, but stability during storage (prior to use) is still a key performance criterion for this sector. For mainstream solar power generation, technologies that cannot operate for more than two decades are unlikely to be viable regardless of other benefits.
Early perovskite devices degraded rapidly. A few years ago, typical perovskite devices would degrade within minutes or hours to non-functional states. Now multiple groups have demonstrated lifetimes of several months of operation. For commercial, grid-level electricity production, SETO is targeting an operational lifetime of at least 20 years, and preferably more than 30 years.
The perovskite PV R&D community is heavily focused on operational lifetime and is considering multiple approaches to understand and improve intrinsic and extrinsic stability and degradation. Efforts include improved surface passivation of absorber layers; alternative materials and formulations for absorber layers, charge transport layers, and electrodes; and advanced encapsulation materials and approaches that mitigate degradation sources during fabrication and operation.
One issue with assessing degradation in perovskites relates to developing consistent testing and validation methodologies. Research groups frequently report performance results based on varied test conditions, including variability in encapsulation approaches, atmospheric composition, illumination, electrical bias, and other parameters. While such varied test conditions can provide insights and valuable data, the lack of standardization makes it challenging to directly compare results and difficult to predict field performance from test results. This affects the entire perovskite research and development (R&D) community, independent of any specific research area, material set, or stability improvement approach."

Wow, renewable energy is such an important topic! I recently came across the Segway Portable PowerStation Cube Series and it seems like a fantastic option for outdoor enthusiasts like us.

We are not the first civilisation that has achieved remarkable things and than disappeared from the face of the planet. This phenonomen has been repeated over and over, probably several times in the planets history.
As horrible as what it sounds, we need to cull the race one way or the other, be it by war or natural disaster.
We are a parasitic and warlike species that needs to be taught a good lesson before we will wake up to ourselves.

Actually , the main reason they want to make it transparent is for heat absorption to be low. Current solar panel has a black surface which actually absorb heats towards earth which is bad as we do not want it to hear our planet, instead we want it to reflect it back outside of our planet.
That is why they do not consider it to be black. I hope this helps.

What are the challenges of bringing this future to light? Well, the person you interviewed is talking about the "Market," so you can see where his priorities lie...that's problem #1 right there...
At a 1/15th cost of solar panels, at 20 year lifespan seems reasonable at least on a consumer level which are more less the same life span as most current solar panel tech, let alone roofs, vehicles, and most applications. It seems that really isn't an issue. And if it's better for the environment with more abundment materials cost.. it seems like they're almost ready to launch.
Very excited about seeing work being done to make solar thinner and more efficient. I’m not a scientist, but have thought about this type of “panel” for phones, drones, cars and more would be great! A s solar Silpat mat!

You'd "only" need 100x100 miles of solar panels...not accounting for weather conditions, power storage, power transfer, growing demand, maintenance, etc. You'd also need batteries the size of city skyscrapers....a whole city of them. You'd also need to replace ALL of that every 10-20 years.

Life itself starts solar powered but you want all the good stuff for yourself with no respect to the actual cost of the fuel you are burning. Get fucked
@@jonathanday4553 There's enough ground juice to fuel our civilization for the next 100,000 years, if not more. And we will ALWAYS use oil, because we use it for more than fuel. We will never stop using oil. Average oil well is 6K ft deep. Deepest is 40K ft deep. There's a LOT of oil. And it's not localized to specific areas. Everywhere on earth, there's oil, if you dig deep enough. Guess what the byproduct of burning gas are? Carbon and water. It's one of the greenest fuel sources in the world....too green for the greedy people in power, so they want to make it seem not so green so they can sell you other things and rob you of wealth.

One way to improve solar panel efficiency is to install blocking diodes between each of the solar modules within the panel. Conventional panels when just one of 60 sells is shaded will reduce output by as much as 50%. This is because the shade itself becomes a load on all the cells that are receiving sun and the energy is diverted. Blocking diode to prevent the solar cells that are in sunlight from feeding back into the Shaded solar cell.
yeah ..nice explantation ....but now a days the solar cells on the modules is devided in to two parts so that if shadow came then this not effect the entire efficiency of module. this technique is genrally use for module powers are arround 400 watt or more than this.
@@alokverma3311 Good to know. I'm experiencing this issue with 240W panels. 60 cells. Cover 1/2 of one of the cells and power drops from 180W to 80W. It's really shocking how little obscuration can cut way down the output.
Bypass diodes are very common nowadays in solar panels
@@basspig 80 is not much less than 50% of 180.
@@wes326 it's way out of proportion to the area blocked (1%) though. So if those offline shaded cells were isolated by diodes, it would help hugely.

This is genius and will quickly be adapted to many industrial fabric uses! I am amped!!
Back when I was looking at them in uni the big problems with perovskites was the inorganic part is usually a heavy metal cation and the film is usually is pretty water soluble. So manufacturing and end of life recycling is a big deal for them unlike with silicon solar cells.
Concentrated solar power is more efficient and easier to manufacture. Polished metal parabola pointing at a heat exchange coil in the focal point. Use the heat of the sun to drive a steam turbine. This process heats water, provides passive radiant heating, and generates electricity.
Considering that heating is the biggest energy consumer. Hence why Canada has the largest geological footprint per capita. Excess heating is actually a good thing. Heat is energy after all. In fact a flame can refrigerate.
@@brendanwood1540 concentrated solar power can be cheaper per m^2 when you have plenty of room and can implement tracking etc (there is a design where the pipes run along the centre line of the mirror so the whole thing basically just has to tilt up and down which looks pretty good for areas where you want fewer moving parts)
There are a lot of places where PV is a lot easier to implement and it is potentially considerably more efficient because there are materials which can generate electricity from at least near infrared all the way into UV, there is no way you could get 50% efficiency in a solar thermal plant. (And obviously they wouldn’t work on a vehicle or a house roof or to take camping or whatever)
PVs have a fairly long lifespan and they don’t require much maintenance before they are at their end of life so you can see why they are attractive for solar farms. Here in Australia a lot of solar farms have been able to pay for themselves in
Glen or Brendan, is there reading material you can suggest so I can read up in detail about Concentrated Solar power? Thanks
@@glenecollins Tracking isn't required. The path of the sun throughout the entire year is predictable at any given latitude.
Likewise a lens could work as well as a parabola. Thermal mass storage would be ideal for this application.
@@brendanwood1540 the path is predictable but if the mirrors don’t move the spot or line they focus on moves throughout the day following the sun so that the focused beam falls on the required area is what I meant by tracking.
I like the idea of buildings producing its own electricity. This can be used for both the operation of the building as well as charging workers cars etc. The main advantage is that this energy doesn't come from the grid. In fact it can top the grid up.
It always irritates me when I see office buildings with window darkening film. They reduce the light by about the same amount as BIPV (building integrated Photovoltaic) panels I was working on in the early 2000's, but generate heat rather than electricity. *8'(
The average high rise office block has way more non north facing window square footage than it has roof space, and roof space is often filled with air-conditioning units for the block.
So, I have actually read quite a few research studies related to perovskite panels. Most of them were from the Institute of Electrical and Electronics Engineers (IEEE). It seems that there are two major issues with perovskite solar panels. One of them was mentioned in the video, but not with a lot of detail. Currently, perovskite panels have an estimated lifespan of approximately 10 years. They did mention durability problems, but didn't really emphasize just how long they are expected to last. They kind of jumped around a bit on it instead.
The other issue is related to this, but probably more important. Because they degrade faster, they also leech chemicals, such as lead (and the other materials they are made of) into soil and waterways which has the potential of contaminating our food supply if placed in agricultural areas, and drinking water if runoff makes it into water reservoirs. Some of the chemicals that leech out are not harmful at the low levels that make it into soil and water, but other chemicals used in the construction have not really been tested to determine if they will be safe for humans (or other creatures) at any level if they contaminate our soil or waterways. Lead is not safe at any level, so that is a major issue.
The ability to manufacture them at such low temperatures is great when it comes to cost and production related environmental hazards, but it also means that they can begin to degrade at those temperatures as well. I'm sure that is what the people in the laboratory are probably working on tackling, but if something like this gets pushed out too quickly without solving this issue, it could cause a lot more problems that the ones it resolves. Hopefully, they figure something out though, because otherwise, they seem quite promising in comparison to traditional silicon solar panels.
Yeah when I saw the extremely low temperature required to make them, I immediately worried about the place where it would be ideal to use these things. Places like Death Valley and multiple locations in Arizona. With air temperatures going over 120 degrees Fahrenheit and ground surface temperatures with the potential to go above 200 degrees Fahrenheit, I am skeptical they could survive the full 10 years projected.
Aww come on guys, LEADED GAS WAS A GREAT IDEA.
Maybe waves/beams of light could be absorbed better if the band gaps were designed to act like an alternating current to reduce reflected light by creating feedback loops. Given the metals can benefit from their light properties, perhaps the colourful oxidised Bysmuth could be strong enough to be used in a pyrovskite layer. It could be a cheaper alternative to Iridium.
Good to know people who develop this understand they do not need to compete with silicon panels in how long they will last when they can provide more power cheaper and for less weight. Needing far less material and lower temperature to make them also means the energy cost of making them is far less, meaning they need even less time to recover the energy used to make them than regular PV panels. And the materials are far easier to recycle too. With such benefits these panels would be viable if they just last for a decade or so, and even that is more for people's convenience than actually needing to produce more power over its lifetime.
It actually starts to seem like the demand for panels to last 25 years was put up by some people who do not want us to have cheap solar panels...
It is troubling to know that BS flawed napkin math by a con artist is pushed as fact by so many sources. PV Solar will NEVER be viable as an alternative.
This is how dangerous democracy has become it's all run by people making money with personal interests. How can we grow like this!! The only way is ACCOUNTABILITY in power no business attached its thee only way to stop the owners of the capitalist businesses. In politics not in business ACCOUNTABILITY NOW
@Ev1l Machine pros and cons. New materials will have a harder time getting in the market, but at least cost of living will go down.
@@excitedbox5705 The BS flawed napkin math is right here in this video. Particularly in the comments. If PV Solar will "NEVER be viable as an alternative", why are there so many Gigawatts already in use? It is a very cheap source of power, and when put on a grid or coupled with storage, becomes very useful. When coupled with wind turbines, even more useful. But you're a fossil fuel pimp or a luddite, I guess, so you probably will disagree.
Yeah Perovskites return their initial investment in as little as 6 months by estimates(even lower by some, but that's optimistic) so a solar cell that last only 5-10 years should still be competitive against fossil fuel or mono-silicon PV.
This was a good video and I'm especially happy you went into the challenges it faces although I always end up frustrated not really understanding how they go about improving the poor aspects. Like, what specifically allows for one of these substances to be more durable to heat and how do they go about trying find it?
I also find it sort of alarming that this crystalline structure was just found in nature rather than come up with. Is it possible theres an even better structure and wouldn't trying to optimize that be the most important step. I mean, it's possible that all this research into perovskite's becomes useless if some better structure is found so shouldn't we first develop the science around finding the best structure?
so i would advise some Real science courses... learn some chemistry and physics....but typically its about finding a material, or creating one that suits the need better. Only quite rarely is there truly only one substance that will work for a given need, but how well it works, or its cost, or potential environmental concerns.... ect., determine what substances are actually used.
We used to use lead as a fixative in paints, in pipes carrying water and many other items. Until many people had succumbed to lead poisoning, we were not aware of the health issues, and lead worked cheaply and well. After learning about the issues, we switched to other materials, some of these alternatives were already used somewhat. But lead was still being used in paints until like the 80's....partially because alternative materials cost more.
Lead based paints no longer dominate the market because better paint types were developed, and at reasonable costs, else we likely still would have lead paint in our homes schools and hospitals.
@@donatoge1713 I mean I understand that, I just don't understand what they do to find or create these better materials. How can the process be sped up.
It would be interesting to see a map of the US showing what size Solar grid each state would need to handle its Power load, but would be interesting to see the power load of each state that way.
bungie is getting really creative with these subclass updates!
When I was working on machines to laser scribe thin film solar panels in the early naughties, all people were talking about was getting the cost down to $1/watt, we hoped thin film was the way we would achieve that, but economics of scale have meant that monocrystalline cells dropped in price far more rapidly than anyone imagined, pricing out cheaper, but lower efficiency, thin film technologies, even Cadmium Telluride (which was horrid to work with, ask and I'll tell you about the extraction system we built).
It's really great to see new options, and perhaps Perovskites are the way to bring thin film and BIPV back to the forefront, if the logevity problems can be solved, but even if they can, industry is slow to adopt technologies that don't have a long history already, so I wouldn't be surprised if we had to wait another decade for Perovskites to make any significant market impact.

I'm a materials scientist & engineer. Just getting into solar technology out of interest. Excellent presentation . This technology step appears to be X2 decades away from a real commercial application. Carry on the good work. Nano Nano.
i'm an old school solar engineer. so new stuff is unfamiliar, but follows the same principles. i'm pessimistic, because I implement rather than research. there are lots of challenges to overcome before commercialisation. efficiency isn't too much of a factor at the moment, even if you could be at 50% efficiency, there would be other challenges to deal with when it comes to electrical.

I remember reading in some magazine around 2000 about 2 technologies for solar. 1 was a paint for your house that would insulate the house (low R factor) and allow solar use. And the other was a film for use on the windows that would still allow light to pass through, but let you hook it into a solar system. I was hoping to really see both develop and this looks sort of like #2. I hope it come to fruition.
The problem always seems to boil down to disruption of an existing money making industry ie pressure from existing corporations to keep new ideas down, or simply ideas that are great but not quite efficient enough in some way or thjere is an alternative with advantages they want. I have watched so many 'breakthrough' concepts just disappear over the years. The best example of this is the nuclear industry - there is a way to use nuclear materials without creating dangerous atomic bomb materials - but the simpler, safer way was not pursued because they WANTED bomb-making capability ! So now we have dangerous power stations all over the world that are a threat ! IOW there are politics involved & money & power driving what happens. It's hardly surprising that we are not yet living in the inexpensive heaven that we could be !
@@veronicaroach3667 the issue is that they are toxic and pretty expensive to make
I like the way you think @Thomas Fisher. To me, since I missed the research and development, both of these two technologies are novel ideas I missed and should be achievable from the day you came across them in 2000. I can visualize a time when a combination of
of ways to capture energy are used in new and old working ways to make use of every conceivable way in the construction of homes/buildings. From windmills, solar panels, and modified building materials are used in combination and surpass the needed supply of energy in a home. The best way I know to do this is make a material list for construction and find ways to modify them to collect energy. The window/solar panels and creative ways to use a paint is ingenious.
Here is s an idea that just popped into my head. Have 2 kinds of special paint..layer them many many times like a battery. A layer that is positive+ charged and a negative- layer charge and in effect, turning the paint into a battery to hold or create a charge. The (+ - + - + -) layered material can collect, store, and make use of the energy.... exactly how batteries and capacitors work that way.. Why not "layered paint" or a prefab house material similar to plywood. The prefab material would be exterior coverage and even work like the current solar/shingles. Think about every construction needs and dual purpose them.
Thomas, and everyone reading this consider what else could be dual purposed. What about ASTROTURF durable enough to handle the wear and tear required? And...COULD a REAL grass be engineered to collect and store energy? This list could jgo on and on. Electric cars don't need a radiator. Why not open up some air scoops or utilize the empty part where a radiator would be and put fan generators in every conceivable spot? Turbines. ducted fans... How about using a rocket or jet engines as a template and take the passing air and reduce the throat to create MORE pressure to collect energy while adding to additional thrust? Maybe use a very heavy element such as lead to make a heavy magneto/gyro, that once spinning will want to stay spinning especially in a vacuum and could store more kinetic/potential energy than any kind of battery. Some of these ideas may not work or be feasible, but some of these ideas will work.
This guy is adorable!! I've seen him in Palo Alto (is my home)😊 plus he's brilliant!
Cool to see more efficient solar power models being researched. Finding efficiency is the crux of engineering.
Awesome video. Keep up the good work
This is science presented in a journalistic style; the advantages and challenges, for the thinking person. Fascinating! Hopeful technology toward renewable energy for sure!
We just recently had solar installed at our home. An array of 19 PV panels, with a Powerwall for storage. Right now, the handy app says my battery is at 100% (so it recharged from powering the house through the night), the house is using 0.6 - 0.8kW, and the panels are producing from 4.8-5.2kW. App shows total we've produced 14.5kW, with most of that going back to the grid.
Cant wait for arc 3.0 now
I look forward to seeing Perovskite solar cells becoming main stream, and hopefully bringing down the cost of solar cell, and improving efficiency on energy generation. It will certainly benefit alot of people then, from all walks of life.
They literally break down to anything even extended exposure to sunlight
I want to see an electric RV with the entire surface covered by these cells as body cladding, and a rollable shade also covered with them for even more surface area. How much charge could you get if you were not merely limited to some solar cells on top, but covering the entire surface? Same for the windows, get some that collect some of the light and convert some into power.

Amazing video, thanks for this
Great video! Not the typical huckster new technology magic video with impossible promises while glossing over potential problems, and not dumbed down to be 98% fact free. I can imagine perovskite solar incorporated into an injection molded plastic enclosure for various products such as outdoor motion controlled security lighting, displays and signage, security cameras.... It would also be great to be able to buy pre-cut rolls of solar film that could be rolled onto a metal or polymer roof, between the strengthening ribs, to quickly produce a solar roof that inexpensive and efficient.

Very interesting topic and well presented! Good job!
Loved this video, very informative.. can you make one on semiconductors?
It’s important to experiment with solar cells in direct or simulated full sunlight, however, I believe in making the cells for the low cloudy conditions. If they do well on a cloudy day they will be totally outstanding on a sunny day.
Cloudy days are not concise or uniform, it's not good for scientific research but they will perform well in that environment, apparently the problem is its fast degradation.
@Charles Martell Yes but solar and nuclear complement one another, because nuclear is hard to ramp up and down, so you have to design in excess capacity that is typically wasted at off peak hours, but solar adds in extra energy during the time of day when usage peaks.
@@hzuiel It's actually very easy to ramp up and down nuclear. They don't do it because the fuel is cheap just like solar if it's fully lit and no one is using the energy than all the energy collected is being wasted. So in other words nuclear and solar both need an energy buffer e.g battery or pumped hydro.
These videos about “new developments” are always interesting, but I’ve learned to take them with a big grain of salt. I used to subscribe to Popular Science back in the 1970s, 80s and 90s and they’d always be showcasing some new technology, only to have it completely disappear after that. There are SO MANY things that can derail a technology. Not only does it have to work, it has to be fairly easy to manufacture, it has to be cost effective, it has to be financed and promoted correctly, it has to pass the myriad EPA regulations, and today it has to be recyclable (otherwise the disposal costs become prohibitive. A good example of how a technology can make a wrong turn, is the straight screwdriver and the Phillips screwdriver. Back in the day, they were both competing for the emerging consumer tool market, but the developer of the Phillips screwdriver wanted more money than the straight screwdriver did, and so most people chose the straight edged screwdriver. It wasn’t until much later that the Phillips got any traction.
Exactly, we public are easily enamored of the 'discoveries' that have yet to be producible due to cost, restrictions, etc., only t discover that the corporates are continuing dangerous and toxic energy productions. The last year has seen global corporates invade the Polish market imposing a dangerous nuclear facility to be constructed on the Baltic, and massive military weapons productions on former farm land used for wineries, etc.
yeah ive seen so many new technologys end up in dropshipping products if you know what i mean
Perovskite's advanyage of crystalizing at much lower temperature (say below 100) is an advantage as well as a drawback. The low temperature enables the cell to be manufactured easier and cheaper on transparent materials, but also potentially degrades its lifespan and problem to operate under high temperatures (eg: 80 degrees or higher).
The trick is to find a material so that before it crystalizes it requires low temperature, but after it crystalizes, it'll need significantly higher temperature to disrupt the crystals to achieve much better stability.
I first encountered Perovskites in 2008, working at an electron microscope company that was supplying scientific instruments to the U.S. National Renewable Energy Lab. NREL was working with multi-layer Perovskites, and they had a prototype "printing" manufacturing method. Again, that was in 2008!
We still are! I just joined
Having a material that will produce more energy over its lifetime than it takes to manufacture (whether from raw materials or from a recycling process) is the first big step needed to making solar feasible in more widespread use.
It's been a long time since that was the case. Very early solar panels, like the ones used on early satellites and space probes in the 60's produced less energy over their lifetime than they cost to manufacture, but they passed that threshold over 50 years ago IIRC.
Aren't today's silicon panels rated at 25 year to 80% of original output. So maybe possible to obtain +50 years from silicon. For 25 years, at average of 90% output with 20% solar efficiency panels and 2000 sunshine hours per year you get 9000kWh. If You pay about $1000 per kilowatt for solar panels (values based on my countries $). If your electricity cost $0.30 then the same amount of kWh's would be $2700. A saving of $1700 over 25 year for one solar panel. With 5kW array over 25 years you would save $8500.
Cities like Brisbane has about 3000 sunshine hours,
@@AORD72 Yeah, a typical "good" solar setup will quote you at about 7-8 years before the cost of your solar system becomes a net profit. So then you have another 15+ years before the warranty wears off, while the solar panels themselves are still working just fine ( they try to doom and gloom you after 25 years with those 80% statements so you'll think to replace it all with a new system ...but what car still runs at 80% after 25 years? )
Your panels will still work for another 25 years if they're taken care of, so that's even more "profit" from them, even if their output degrades over time. ( But consider how the planet is changing over the years, sunlight becoming more frequent over the year compared to previous ones. ). Not to mention you're paying for the panels now, while your electrical grid costs will continue to rise and double. The cost savings, and the relieving of stress on systems, is exponentially increased as years go by. It's like buying a home .. the sooner you do it the more exponential gain you get from it from not giving that money away anymore, and having peace of mind of it not being dangled further and further above your head.

It's great they're being honest with the fact there's issues with the tec currently.
I'm feeling a lot intelligent compared to yesterday. cool video!
if the cost is really 15x cheaper per watt than silicon, then it would still make sense for large solar farms. Just part of the setup would need to include either automatic install/replace or very easy manual replace. Just making it twice as cheap(including the replacement process) over say a 50 year period would change everything.
How well it can withstand outdoor activity, being #1. And replacement and such, labor costs of installing, etc adds to it as well. You don't want large solar farms having to have them to always be replaced.
Isn't 15th time cheaper per wats, is 15th time cheaper per kg, because the active part it is more thinner, but on average is tree time cheaper, and life-span is somewhere between 7 and 15 years, so worse than today silicon solar cells.
@@toddjohnson7572 Once the infrastructure is in place, the base, the inverters, the battery bank, its a quick job to replace a faulty panel.
Isolate the panel, unhook the electrics remove and replace [panel, re-hook electrics, and you are off to the next job in 15 mins.
The cells could be mounted on sheet metal, which is hardy and relatively light, while retaining shape in hot sun.

This new solar power application is amazing! Might work in the Pacific Northwest, where it rains constant for 6-7 months. "Grey" skies... no sunshine. Few solar panels here.
Might be interesting to add an electret below the solar cell to change the band gap of the semiconductor junction.
Also a thermoelectric layer below the solar cell cooled by water could increase efficiency and provide free hot water at the same time. Best wishes for success.
Perovskite solar cells have been in the news for a very long time... and not a single residential product available yet. You cannot claim it is cheaper until you have a working product that lasts. To make it last, more expensive components may be required - which means its not cheaper anymore.

How about integrating photovoltaic with radiative cooling panels? It will keep the panels cooled sending heat to outer space through emitting specific infrared frequency that escapes atmosphere. It will help with durability issue dramatically!
It's a good thought but fluid based systems have issues of their own. Fluid tends to be hard on materials, and active solutions with pumps and valves will wear out.
If you design something to be cooled, what happens when that cooling fails? What fluid will you be using in the loop and will it be bad for the environment if it leaks? How much of your power being produced is dedicated to the cooling solution?
Many solar plants already have high work hour demands with just cleaning the panels, and that is low income work. Plumbers and fluid engineers are much more expensive. In household solutions it can make sense (the products do exist), heating your hot water tank and providing power with the same device but the issues are still the same.
India has been using a middling strategy, they are installing solar over canal systems and water reservoirs. Evaporation from the water lowers the temperature of the panels and the shade the panel provides limits the water lost to solar heating and evaporation. It is a passive solution that still lowers the expected lifespan due to moisture levels and corrosion, but the cooling makes the panels much more efficient while they work, to the point that the tradeoff is worthwhile. This solution also improves cleaning effectiveness, water is very close so you don't need as strong of a pump, and the water drains back into the source rather than the ground.
Nothing is perfect but smart people over time eventually get to simple and genius solutions, who knows what people will come up with!
I did a paper in college about using space based solar farms that use microwave technology to direct that energy back to earth. This idea could also be used to stop tornados if you think about it.
@@Shoi5 Do you have reading comprehension deficiency? He is not talking about fluid cooling solutions AT ALL !!! Read again where he mentions *"radiative cooling* panels" ...
@@AscendingApsolut they would have to be mounted directly behind the solar panels meaning they would radiate back through the panel further heating it or the home beneath it not really good either way so you would have to transfer the heat away then radiate it up to work heat pipes would be a good solution they require basically 0 maintenance with super fast heat transfer would only need a fluid bath on one end could be used as a solar water heater fluid could be used to heat homes in winter or used for preheating water used in water heaters etc I know they are developing new materials that can turn heat into electrical energy and this would be a good use for that heat also further improving efficiency of the system

@@Dragonorder18 i just discovered Ambri the other day, this was their main selling point for their liquid metal batteries - reusability of materials
Battery tech continues to improve. But for grid usage, batteries are probably not the best solution. The best solution for grid storage might be mechanical or conversion to hydrocarbons (which can then be used in applications where electric doesn't work well, such as heavy machinery and air travel). You can use electricity and water to pull CO2 directly out of the atmosphere and create e-diesel with it, which when burned, releases only the same CO2 you previously pulled out, so overall neutral to atmospheric CO2 concentrations.
