Do you believe that perovskite technology holds the key to revolutionizing the way we harness solar energy?
If long-lasting two-layer perovskite cells that are offset printed onto rolls of mylar film are manufacturable, that would reduce the cost of cells to a tenth of current cost of TOPCon PV, reduce panel install cost by a similar amount, and reduce land requirements by a third. Overall, a halving of cost perhaps. Not a revolution but a very useful advance.
Awesome! I'm so happy to be a subscriber again and enjoy your Planet A essence videos. 🌎 I appreciate how you cover one general topic in each video and then dive deeper into specific aspects of it in the following ones. It makes your content more informative and engaging. 👏 What inspired you to start this series? I'd love to hear more about your journey and passion. 😊
I think it will nudge the needle further in making solar the #1 electricity source on Earth not just on cost but also market share... When is the big question... Kind of like fusion power and/or hydrogen aviation/shipping...
From what I understand we already have more solar cells than we have people to install them, so I'm not sure if they'll significantly reduce the cost of installing solar. Perhaps the biggest gain of perovskite cells is that they could potentially decarbonize the solar cell creation process.
Can we make car roofs of solar panels to revolutionise Electric vehicles?
"So these base materials more abundant than silicon." This is the boldest claim i have ever heard.
Well the scientist said it alright, they are abundant enough so it shouldn't be a bottleneck for production....
In crustal abundance, yes. Only oxygen is more abundant. But silicon for PV is reduced from high-purity sands, which are fairly rare. Most sand deposits are full of contaminants of various kinds, and removing the the contaminants adds to cost and environmental harm.
They usually harvest it directly from Quarz crystals @@gregvanpaassen
that made me scratch my head too
@@gregvanpaassen what means silicon is more abundant, just harder to process in a economically viable way.

The claims about perovskite being the next generation are exaggerated. There's a reason why this has taken over 10 years of developing and still have yet to create a marketable product compared to monocrystalline. They are incredibly fragile to hail, heat, and rain which leads to much higher rates of degradation, compared to monocrystalline which is why they have not provided that data. They refuse to send that data because they don't have it, and want to continue to get their government funding that the tax payers are funding because their whole program is more than likely a money laundering scheme defrauding the taxpayers of these countries they're researching and using those taxpayers funds in.
For perovskites to actually take off as solar cells, they have to solve that degradation issue first. Unless they want to sell the panels for $1 usd or less a piece, because you'll have to completely replace every panel in less than 5 years...
Yes the per watt cost is important. You will need to calculate and account for panel life span. Additionally if like mentioned in the Video if labor costs are approximately 1/2 half the Total installation cost the long lifespan panel is critical.
@@jbranche8024 with a bit of clever engineering panel replacement can be done by the user. meaning only the initial installation would be costly.
@@danilooliveira6580 Industrially, too many panels to swap in solar farms. Insurance wise, replacing it yourself may result in a lengthy and costly claims process, if not outright claim denials. Locationwise, solar panels in residentials are typically placed in relatively dangerous areas(slanted roofs) where I would not want a 50 y/o w no experience and questionable balance/physically from attempting an install/repair. Ideally solar panels should be a install and forget solution by which it works through the lifetime of the roof however as several commenters have pointed out, degradation/cost continues to be an issue.
that! severe degradation in one year i think. if they can extend life cycle to 25 years than we can talk
And the toxicity issues.
Longi Solar just unveiled a 33.9% efficient tandem solar panel utilizing silicon, layered with perovskite. I think this is the future of solar panels, for many years to come. The solar panels I put on my house, 8 years ago, are 17% efficient, and that was about the highest efficiency, at the time.
Let's see... Your panels are eight years old and still working, right?
it is not a panel...
They have a cell. Not a panel. Also the 33% are probably not under STC (standard testing conditions). In the lab they use way more intense irradiation which you would never have outside. And the efficiency is higher under stronger irradiation.
@@eatcochayuyo To add to that, as the video pointed out, will it stay at 33% efficiency! As someone who switched our family to EVs and is in the middle of doing geothermal, I really want to see a day where solar panels are converting 70% of the light hitting it and are storing them in batteries that last 50 years with triple the energy density we currently have, but this stuff is vaporware at this time.
What is the highest watt panel available of this company, what will be the compitable inverter
Solar perovskites are genuinely top 3 technologies I’m most looking forward to. Perovskites, tidal energy, and sodium ion batteries are capable of being the 3 most game changing technologies out there, and I really do hope to put some of these panels on my future cabin to feed into sodium ion home batteries.
What are the oder two technologies that you're looking forward to?
Tidal? Interesting choice! Where do you see that implemented?
I'm waiting for the same 3 things, with nuclear fusion
Sodium ion batteries basically work in similar fashion as lithium ion batteries do. They suffer similar kind of degradation over charge-discharge cycles. VRFBs are the more interesting ones because they can last indefinitely, at least in theory.
@@freezepaladin what means vrfb?
I thought the sodium atoms were 6 times larger than lithium, which would make batteries 6 times bigger
Nobody seems to talk abt the issue that the materials used in perovskites also needs to be cleaner as lead is very poisonous and not easily disposed.
You nailed it here. Swapping nontoxic silica (as long as it isn’t inhaled) for toxic lead containing perovskites seems like a poor trade.
And considering the vast land area over which they'll be deployed makes this an even worse proposition. Not to mention some people love putting those things over farm land as well.
@@djmotion86 heavy on the "farmland" argument! Things can go very badly
This is the most complete video about how perovskite solar cells works that I have seen, thank you very much.

The ingredients are DEFINITELY not more abundant than silicone which makes up 27% of the crust
methyl-ammonium chloride looks like it could be made out of ammonium,
Lead makes up 0.00099% of the crust
And Iodine 0.000049%
The availability, ease of production or energy efficiency of making the Perovskite panels may be better, but basically nothing is more abundant than silicon
agreed
Thank you! Had a double-take on hearing that claim
I think what he means when he says they are more abundant is more about the purity if the silicon and the other materials in a panel.
haha same, I just got so confused by that claim as well :S hah
Thanks for catching this! So, we regret not formulating the sentence more clearly. We realize now that it could be construed as misleading. As other commenters have pointed out, we are referring to the availability of high quality silicon that can be used for PV. We didn't mean it's more abundant than silicon dioxide. Sorry for the misunderstanding 🙏
Great video!! Learned how perovskite cell can be cheaper and efficient but stability and toxicity still remains a challenge.
One of best content I have come across it shared some light on what direction is the solar-power industry is taking for the future.
Like to send my thanks to this channel for providing me with good Intel and knowledge of what is to come in the near future of power generation.
I feel like dual tam + lenses to focus light for more area coverage per panel + collecting of the wasted heat into water or power generation would give you the best bang for the buck. Lenes cover more area per cell that generate extra light + heat (lets say 4 to 1) that you then run cool water under to help keep them under temp - that cool water is heated and store into your hot water heater or the extra heat turn into direct power, the extra light gets turn into more power directly. If the dual tam can cover the IR light too - that means less wasted heat/heat increase on the panel , but that also means you can cover more in between with the Psok method between the light panels - as IR is the one that gets wasted the more currently anyways.
I hope this can be adopted quickly
Tandem Cells would be a nice option to consider when going off grid. Thanks DW.
My friend and I were just discussing about the largest wind turbine and uber-efficient solar panels. At the same time I see your upload “10 minutes ago”. Of course I shared this video with him ☀️
Fascinating work. Love from Upstate NY, USA ❤
Your phone spying on you...
Exciting. Love from India :)
Save world and stop pooping all over india!! Stop it!!
I've missed science news in news channels. Hope to see more of such videos here.
yet, at the same time when the message is "PV is just around the corner" for at least 10 years or so, news no longer feel like news 🤷
👏🏼👏🏼Go ahead and place ongoing discoveries 👏🏼👏🏼I love them❤❤❤❤❤❤👏🏼👏🏼
good
Until they can make them without lead, I don't see widespread deployment.
Solar already has enough issues with the people who argue about it ending up in landfills. There is actually some good progress in solar recycling and refurbishing now though but I feel the real solution will be reselling used solar from solar farm operations to individuals at a low cost, they may lose quite a bit of efficiency but they can still be fine for individual residential purposes or to subsidize energy for public buildings or homeless shelters and low income housing solutions.
Slavs are saving the world again! Bravo!
Nice report. Decent level of detail.
The most straight forward way to decrease installation cost per kw is to make each panel more efficient. So I think we will see multi junction commercial cells in some years. But it is not sure if Perovskite cells will win out
I have also seen some interesting work on using lenses to focus light making solar cells that use less actual solar capturing materials. There is some interesting work on making transparent solar cells tech that can be used inside windows on high rise office buildings, they have relatively low generation as they only absorb light on the non visible spectrum however they allow you to put solar places you can't put regular panels.
When a breakthrough is announced, the rollout to the market will be fast. Good overview of the technology development, thanks for the update!

perovskite solar cells are exciting to see.
Currently my 60 watt portable panel is quite big. at a rated efficiency of 22%.
Imagine how much smaller it could be with a 30% efficiency at the same wattage!
You're not only getting higher efficiency, but you're also getting smaller panels, for the same wattage as older ones! I can't wait for perovskite solar panels to hit the market.
As long as they are cost effective (i.e same, or below current solar pricing), and actually live up to that 28%+ efficiency, thought I would like to see 30%+ efficiency.
In 2018 I was making a college work presetation about that and now it seems to be closer for us tô use it.
Last December, the world's “first commercial” solar power plant using perovskite solar panels with a capacity of 1 megawatt (MW) came online in China. The modules for it were developed and manufactured by the Chinese company Microquanta.
The price part would come down with volumes (that's why it's really getting cheaper) so the cost side can easily be solved - if they really work.
Tandem could be great in applications where space is at a premium like vehicles, which could allow them to succeed even if they are more expensive per watt.
I'm glad I watched this. I'd heard about perovskite plenty, but was still under the false impression that it was mined out of the earths still, and not created so easily.
Also the host was enjoyable.

Making metal coating such as made reflective glass on perovskite layer could be a solution against moisture affect or laminating it between two glass sheet by using pvb also could be a solution against deformation because of ultraviolet!
Great to learn about new innovations but also good to know about the new commercially available products that are coming out. This is great and all but if it's still 5+ years out who knows if this will ever be realized. A mix of both would be great. This might be coming in x years but right now the latest and greatest just became available which is....
Awesome content ❤
Nice video. Very informative. But at the end of it you've mentioned the Oxford company which proposedly had made much more progress in that area. So it makes you think why you didn't go and interview them instead haha
Interesting, thank you.
Regarding the ingredients: silicon is very abundant, as it is the second most abundant element in the Earth's crust. Lead on the other hand, while not as rare as gold, is orders of magnitude less abundant than silicon... The real difficulty with silicon is in growing sizeable high quality crystals.
Right, was annoyed at the implication that silicon is rare or something
Wow almost 30% amaizing....
The ABX3 crystal structure will always be very unstable compared to doped silicon. We can make 50-year panels today...
A replaceable perovskite- glass front with a 5-year lifespan - is an excellent compromise.
I think the real value here is coatings that produce a charge.. light and translucent, it could be placed on vertical surfaces.
Hanging a roll of plastic and connecting it to a micro inverter - the installation will cost nothing...
Excellent explanation
I disagree that cost per watt needs to be cheaper for perovskite. For solar farm use, yes, but for things like solar panels being put on the roofs of electric vehicles, the biggest issue is panel efficiency, there's not enough roof space right now for it to be very useful. But if it was 10% higher efficiency, maybe that's enough for EV manufacturers to consider, even if the panels cost something like 50% more.
Thanks
Cost of perovskite alone will not determine adoption. Ultimately it’s the price of energy that determines adoption, not the price of perovskite. Upfront costs are irrelevant if they can be recouped later during energy production which may be as much as 25% greater with perovskite.
So a solar cell with and expiration date I'm sure this will be great, can't wait for planned obsolescence to set in
Kafie sarahnia hai Dhero subhkamna wa badhai hai
such a cool dok, dankeschön :)
We r using bificial solar panels right now hope we'll get the latest technology asap
Perovskite cells are like fusion: it'll always be a few decades away
It's actually the other way around.
Those cells are already here, but won't still be a couple decades later.
No, not even close. They are already commercially produced in Saule Technologies in Wrocław, Poland. They are used already to power shelf price displays.

Just DW does not know about it because they are so German oriented. Well, what can you expect from Germans 🤣
Need to discuss the lead. How to prevent lead contamination of the environment when these break or wear out?
There are tin-based Perovskites as well as lead-based. They are a little less efficient, yet can still compete, it seems, with silicon.
Your video which i watched is so good.
Solarrr ❤🎉
Thanks for reuploading the old video.

Hey James! Yeyy, we are glad to hear that 😊 we post a video on the repairment culture in India this Friday. Excited to hear how you like it!
Good👍 to hear, the adoption of solar is very low though
Cool just got my solar done on my home. Maybe down the road by the time mine degrade I can upgrade to these. They might be commercially viable by then
I wonder why they don't use the silicon layer to protect the perovskyte layer
The currently poor longevity of perovskites may be less of an issue with shorter lived commercial goods like devices, clothing, accessories or backpacks that need power.
Another benefit is that the very low weight of thin film perovskites (even after encasing) may allow installation on roofs and surfaces that would otherwise require structural upgrades.
So nice content love from India ❤

It doesn't matter how efficient a solar cell is. When your area of the world is not facing the Sun, your solar cell is producing zero power. When it is winter in the north, you only get 8 hours or so of daylight. The further north, the more darkness.
So when you need the most electricity, you get the least light.
Maybe one day when there is very efficient and cheap battery storage will solar finally be useful.
Battery storage is already getting pritty cheep. About 2.5k for 15kwh last time I checked.
I really hope someone has a massive breakthrough for solar somehow....I'm dying to get some but the cost of using an installer are huge.
Great good job😊
Hey Yousaf! Glad you like our video.😊 We post videos like these every Friday. Subscribe to be notified! ✨
lets go using this video for my chemistry assessment
"Everything is possible so nothing gets done." -S.Westfield All these home energy technologies are developing so rapidly in parallel, all hold promise but none of them are cheap nor ready. So as a consumer trying to save up on a solar array & home battery, I'm really overwhelmed & discouraged with the likelihood that whatever I choose will obsolesce at a savage rate both in inherent value and relative efficiency. It could be perovskite, lithium-sulphur, iron/air, solid state, carbon,.....and/or rapid improvements in any one of the many different chemistries. Doesn't matter. So I fear there's really no point researching/educating myself about anything now if my system won't get installed for another two or three years.
whatever you do today will be worth the cost, even if its a bad investment in hindsight. all that it means is that in the future you can easily upgrade everything for a even more efficient technology when you calculate you won't be losing money.
Can't wait for the "tough perovskite" g-shocks...
Its decomposes super fast in humidity
We need to be looking into ways of using the thermal mass of solar panels as a means of energy generation too.
Are you thinking about hybrid panels? Producing electricity and heat at the same time?
From what I'm hearing there's still a way to go and it may make more sense for larger installations until the cost levels out, maybe 2026?
It's a good and informative one

Please cover the Oxford perovskite as well. Thanks.
Check out 7:24 of this video - our reporter covers work by Oxford PV ✨
Not true that perovskite components are more abundant that Si, which is what the Earth's crust is mostly made up of. Also the video (at least the first half that I saw) does not consider the fact that perovskites most often contain lead and/or barium, both extremely toxic materials, and combined with the fact that perovskites are not particularly stable materials , mean that a damaged cell carry the risk of environmental pollution. So the bottom line is that there is still lots of research needed for perovskites to push out Si in commercial solar.
A 30% efficient solar cell would allow me to put a lot more kw's on my roof! I do hope perovskite technology finally gets commercialized in 2024 but solar panels with perovskites having been "coming soon" for several years already.
Have you looked into pv graphine panels?
Hey perhaps they should also try using some sort of quantum dots or structures which enhance processes!
Can you also use perovskite in batteries? I read about batteries with silicon anode, but could perovskite be used instead?
That's a good question - and one researchers are actively trying to answer. Many say it's promising BUT the technology is not quite there yet.
Here are some additional resources on the topic:
📚 Nano Energy: The study says they need to conduct more research, but metal halid perovskites are could be promising for lithium-ion batteries (LIBs) and photo-rechargeable batteries. www.sciencedirect.com/science/article/abs/pii/S2211285523004834
📚 Journal of Energy Chemistry: Researchers suggest hybrid perovskites in energy storage would be the way forward www.sciencedirect.com/science/article/abs/pii/S209549562200211X
📚 Advanced Functional Materials: Here, researchers find it's not suitable for energy storage onlinelibrary.wiley.com/doi/full/10.1002/adfm.202206958
P3C
Normally with a labile material it is possible to devise an accelerated test if you understand which environmental factors are impacting the material. That’s the key here. Once you have an accelerated test it’s more efficient to tweak the formulation in development, as short term testing can then validate your hypothesis and changes.
Current solar cells and tech in general would have been considered too good to be true just 20 years ago. I can clearly remember it, I was there.
In the 90s solar cells where funny gimmicks at best. It was dream dancing on the same level as fusion power.
Renewable energy HAS come a long way. Even fusion could be in the cards one day. Check out our video, "Is nuclear fusion the key to fighting climate change?" here: czcams.com/video/eyHovWQ49MI/video.html
The inventor of the Perovskite solar cell is a Japanese professor named "Tsutomu Miyasaka".
I hope this tech is available and affordable to everyone even low income community worldwide. Megalomaniac corporates & politician please stay away from getting involve
Improving the effectiveness of pv is great. But a lot of the cost is installation. Why doesn’t a logist/ construction company start knocking dollars off that. Self deploying flat packs? There’s got to be a way to bring that cost down.
Plastic fiber wind panel is in the row to compete🎉
This material seems to have been, at least in research, around for two decades now.
We have heard of new composite solar cells for years...but nothing is more durable than silicon that has been used since 1970. I doubt nothing will change for another 20 years.
Hey there! We tackled silicon more in detail in one of our videos and its challenges. Check it out and let us know what you think 👉czcams.com/video/ydiX4Iayosg/video.html
Percentages are obscure and obtuse if you don't give the actual expected wattage per area.
45€ for 400wpeak right now, 120 hours of sunlight and you have the price back
Cool, but needs more time for commercialisation
Recently it was reported, that one of the big AI companies had produced positiv outcomes on material science for batteries. Is there anything like that in the works for solar cell material science?
They have been saying the same thing for years and it’s always next year. It’s like nuclear fusion, there’s always a breakthrough, and it’s always 10 years away.
Also silicone is one of the most abundant minerals on the planet while the components of perovskite are very rare in comparison.
tl;dr:
So perovskite is promising because it is not made out of silicon that needs high temperature to manufacture, but lower. Except that the high efficiency only achievable when you do layer it on silicon.
It also degrades due to sunlight, water and high temperature exactly those things a solar cell has to withstand.
..
At least the puffy arms look funny :)
Look for multi-layer Perovskite as the ecnomical and practical solution. Its already under development.
I hope so, but we are actually waiting for the cheaper battery, hope sodium ion battery can be more efficient to store the electric energy
I don't see why not, but it should last as long as tiles on the roof!!
Tell me when degradation is solved. I've known about perovskite for years but we still have the same degradation problem
I am interested in this project
Can this project be started in India also?
Awesome.

Its great and very exciting. However the biggest hurdle for green future is battery, not solar panels (ability to charge ev cars in 5 mins and a range of 600KM with minimal lost of charge in extreme weather etc). When we have that battery, entire countries can be run by battery power including phones that needs to be charged once a week
And, how to make those batteries, recycle and so on...

woww
perovskite potential already been talked for more than 5 years and I don't really think it ready yet, at least for another 10 years
