Perovskites are a class of materials that have a cube-like and diamond-like crystal structure. Though the first perovskites were discovered more than 180 years ago, they were only applied to solar cells within the last two decades. They work the same way other semiconductor based cells do; light from the sun excites electrons in the material, and those electrons flow to conducting electrodes and generate a current.
In 2006, perovskite cells were about 3% efficient. Fast forward to 2020, and some researchers were boasting 25% efficiency. For comparison, the first silicon solar cells were created in a lab as far back as 1940. In the 80 years since then, they’ve matured steadily to the point where they are now typically 15-20% efficient.
But while silicon cells are getting cheaper all the time, they’re still relatively expensive and difficult to make. Perovskite cells, on the other hand, can be made with simpler manufacturing processes like printing the crystals onto a surface, so they have the potential to be much cheaper.

The reality behind solar power’s next star material
www.nature.com/articles/d4158...
Oxford PV, for instance, intends to make tandems this year that it says will be one-fifth more efficient than top-end commercial solar panels. If rolled out across the industry, the total power output of solar panels made annually would leap by that same proportion.
This Solar Cell Just Set an Astounding Efficiency Record
www.popularmechanics.com/scie...
The cell in this research is a tandem cell, meaning it’s a single cell that has multiple wavelength phases. Think of this like first sweeping the floor and then using a mop: you’re catching different kinds of stuff by using two approaches.

I was worried in the mid point he was going to say It's an April fools prank and none of that cool stuff existed.
Wow really hope those downsides get figured out because *dang* 30% - we're getting really close to combustion engine levels of efficiency!
30% efficiency is about 300 Watts Meter square.
The 30% efficiency was the new solar sells working in tandem with existing solar cells. Not by themselves
@@Medabee8 I mean yeah. So what? If composite is best, that's the way forward. I'm more concerned with overall solar panel efficiency than the efficiency of a specific material. That part is just the stepping stone to get us there.
ICE is about 20 to 25% efficient
Solar cells are so inherently needy.. People think you can just put stationary panels on a roof and everything will be great and super efficient😆
I take all videos with hip of salt which are relseaed on april 1st ;
That’s a salty perspective
I dunno. This one seems reasonable
@@bestintentions6089 lol
Same
Hips don't lie, though
How about a video updating us about the development of graphene as a capacitor......like 5 years ago, there was a lot of excitement about the possibilities of graphene as capacitors to power our portable devices. I really haven't seen anything in a long time on the internet on the subject.
They sound prefect for the first temporary Mars bases.
Yep I was just waiting for him to point out the Lead issue. Kinda a big deal.
Better lead than arsenic.
What if you tuned the crystals to infrared wavelengths and used them on the inside of a roof to use the heat that collects there?
According to the second law of thermodynamics, you can't simply turn heat into electricity.
@@Theo0x89 Let me rephrase: Not heat. Infrared light.
@@colleenforrest7936 The second law doesn't care about phrasing.
We should make a substance like alloy by mixing perovskite crystals with any other material which retains the properties of perovskite crystals but also resolves the disadvantages of perovskite crystals.
After that as you said that it can be painted. Then shouldn't we paint our houses with the upgraded perovskite material including the frame of our glasses and everything around us.
Really amazing and helpful video. Thankyou seeker.☺️
Plz touch on the subject of indoor thermo electric paint as a way to charge off grid power systems
Excellent ! This would perfectly fit into my Sci-fi novel ;-) Thanks !
I find it curious that all anyone talks about is producing more power and not finding ways to need less of it.
Effort in that field is required, however, more energy generation is always appreciated.
In my opinion, having more tools and potential (i.e. having more energy avaliable) is just as important as needing less energy, if not more so. There are fundamental limitations to efficiency and cutting back on usage.
So I agree, discuss it and pursue it! But generating energy cheaply allows for a greater toolkit than solely working on efficiency.
@@treasurehunter3744 I agree. I was only meaning to point out that a disproportionate amount of research and funding seems to be invested in more power not less waste. Kind of like our government >_>
A: "Hey I got a job offer for you it pays $10,000 per hour".

What you need to do after writing that, is hold up a package of Mentos Mints and smile like they with Footos
in the rock video from the Foo Fighters - Big Me.
That his both hilarious and appropriate 😂🤣
$2.7 :P
At the time of publication of this material, the first factory producing perovskite cells using the inkjet method was launched in Poland.
looks like alot of youtubers forgot today is april fools day i mean no pranks
How about mixing Perovskites into Super-Hydrophobic clear coat?
This is actually interesting material!
Printed solar panels! How cool (or hot) is that? :)
I was worried this was an April fools prank, but luckily I've heard of this technology before. Sad though that it seems to be advancing slowly :(
Is that what you gathered from this presentation? It's had faster conversion efficiency gains than silicon cells in the same timeframe. Fundamental science takes time.
@@MikeTrieu true
I'm glad I still have my bedazzler. My house and denim jacket is going to be looking fabulous.
Photovoltaic cells should be semi-spherically shaped instead of flat to increase their surface area as well as receive sunlight at any time of day. In addition, the surfaces should be covered with semi-spheres to further increase surface area. In addition, photovoltaic cells should be multlayered with gaps between cells to capture reflected sunlight. Finally, the cells should not have a glossy finish, they should have a matt finish.
So early I'm still at work
Perovskites multi layer can reach upto 50% efficiency in lab tests. The future is here 😃
Nope - I just performed a Lorentz boost, meaning the future is over there
Glad your listening!
One day you will get
Double the power! You have to start somewhere ! We need more people working one this ,Why do we have a high unemployment rate anyway.
I audio in this video has some problems, it was very hard to hear in the first half.
Perovskites are unstable but we have a lot of strategies to solve this, we can passivate the grain boundaries with multifunctional molecules or inorganic compoundd (electron donor-acceptor functional groups, hydrophobic organic chains, electronegative atoms to stabilize the structure using strong hydrogen bonds and delaying the crystalization what diminishes the defects and pinholes while growing larger crystals,perylene based structures for conductivity and improve charge collection or even inorganic dielectric oxides for this passivation), encapsulation of the device makes them live for as long as 1 year and some months, self healing of the material using doping or even self-passivation, we can create 2-dimensional Perovskites that are more stable, we can make them really efficient with multiple approaches like using Perovskite based quantum dots to recycle the light that wasn't used in a Photoluminescence layer behind the Perovskite absorber, we have billions of combinations of Perovskites that can be more stable and efficient, the Lead thing isn't really a problem because the quantity of Lead that is necessary is milions of times less than a lead-acid battery, we make films with nanodimensions so the quantity of Lead is really low (40kg of Perovskites produce the same energy as 8 tons of silicon) while the silicon production process use sulfur hexafluoride and other damaging chemicals way worse than the lead in the perovskites, and if some regulation agency worries about it (without reason because as I said, the lead is almost inexistant) we can make Tin and Bismuth based Perovskite although they aren't so efficient as the lead based ones and are way more unstable because of the Tin oxidation states), well, if I would say everything is happening in this field I would be here for months and months, we are really getting closer to hit the market and make solar energy the cheapest form of energy, decentralizing thé energy production, creating new technological and business opportunities, Perovskite can be used not only in Solar Cells, they emit tunable light for LEDs, they generate charge carriers that can be used in Photo and electrocatalysts, solid state batteries (Li and Na) based on anti perovskites as the electrolyte and 2d perovskites as the cathode, cheaper and flexible sensors and the list goes on and on, this synthetic material is really revolutionary like the MOFs and other classes of synthetic materials, I'm way excited to work with these perovskites and grateful for this opportunity. Any questions I will be glad to answer
Finally some sensible comment which isn't discussing about april fool!
I’m telling you those crystals give out some rad energy
A: this could potentially revolutionize the solar industry.
A again: it was an april fool joke!
How do they mine perovskites?
What if we tandem them in "reverse"? Like silicon on the outside and those perovskite on the inside? Or add other materials such as quartz to shield the perovskite? Cause 30% is nearly as galium carbide if i'm not mistaken(?)
Usually when making tandem structures higher bandgap material (perovskite in this case) is placed on top and lower bandgap material is placed on bottom to minimize the thermalization energy losses. Also, using an opaque material with an indirect bandgap (e.g. Si) as a top cell will leave almost negligible chances to transmit the higher energy light to the bottom cell.
@@mritunjayaparashar7996 oh I see then, thankss
😂 😂 😂 Solar cell that breaks down when exposed to light.
How much iron does it contain to be that ironic
you mean ironic?
2:50 What about covering areas on the Earth that won’t subject the crystals to advanced degradation? For example, why not cover large areas of Antarctica and the North Pole with these new types of solar panels? I know that due to the axis on which the Earth spins would mean that there would be long periods of time where they wouldn’t be able to generate sufficient levels of electricity, but at other latitudes, maybe we could see something like nonstop exposure to sunlight for six straight months at a time. Just a thought. ^^
doesn't salt have a cube crystaline structure?
Aloha 10th
#askseeker, what is better in a Dyson Sphere- reflector panel system or solar panel system?
Neither, Dyson sphere is impossible at our current level of technology.
@@JJs_playground Just pretend that they asked about a Dyson swarm instead.
One thing we could do is change from AC to DC power so we don’t have to convert the energy. Natural sunshine is DC power, converting DC to AC power causes a significant loss...
most of our devices today, laptops, cellphones, tvs, led lightbulbs could run on dc directly, no?
@@elgracko - Yes but manufacturers actually make them to run on AC power to be compatible with home power outlets. It’s kinda silly if you ask me...
@@brandonleesanders yeah, totally agree. would you suggest a parallel circuit for dc?
like for houses that produce enough electricity to unplug from the grid...
i think they use ac because transmission losses for getting the juice to your house is lower, just btw,
use them to concentrate light to small target, and re-use cadmium-cadmium-oxide solar-cell-diodes, yellow
Nice video.
You're amazing
Amazing!
Coating the cells in layers of themselves and be set up in greenhouses worst case scenario, allowing more focused and managed light while dry. Painting over degraded wear would resist losses from punctures or imperfections
its not carbin neutral do you know how they are made the solar panels? the silicon waffers to be exact.
Maybe we need kyber crystals next?
I been rarely watching this channel since the redesign.
I read an article about a month ago of solar panels reaching to 30% efficiency, take with a grain of salt but I think this vid is not an april fools.
Yeah no it’s 100% an April fools joke. Solar cells made of lead that break down when exposed to moisture and light would destroy the environment lmao
@@Notadragon621 damn :/ I'm dumb. I seriously hate April fools ngl
Superhero:My Powers is That I Use Light To Generate Electricity
But My Only Weakness Is Light
Me:😑
How much carbon emissions does it takes to produce this? Or they shouldn't emitting ?
Electricity from conventional silicon solar panels is already the cheapest form of electricity available today. Levelised Cost of Electricity (LCOE) studies confirm this. We don't really need a new type of solar cell using a new type of material such as perovskites.
We do if we want to apply PV to mobile applications where weight is a significant concern. Any technology that can be manufactured in a roll-to-roll fashion is still highly desirable.
Also seeing how that they are more like batteries other than regular solar panels regular solar panels and they degrade quicker I think if a degrade quicker I think companies would be more apt to commercialize those yet commercialize those because of that fact so they could have a turnaround like so they could have a turnaround like dorisso batteries they make their money on the re bound
Lead? Yeah they are going to need to find another material. I am guessing the Lead is also why the Perovskite Solar break down so quickly. Lead is after all a soft metal that has a low melting point.
What about all the industrial waste created from manufacturing and a short life?
I thought there was gonna be an ad in the middle
What if we paint moon with this material,free energy
Stop zooming in and out on is face for godsake! I made a drinking everytime it happened
Best solar material ever!!!!!!!! But it last a few months haha April fools!!!
So if the silicon transistor can convert 15-20% and the crystal transistor 25%, does that mean that a hybrid cell could convert 40-45% of the sunlight into electricity?
Bottle necks. We'de only likely get 35% out.
@@josephnigel8811 Thanks
maybe ideal for deep space missions, no?
very little oxygen, heat or moisture in space
plus the high efficiency would help soak up the little light that might reach a probe. *the high lead content wouldn't be a problem either, except for **maybe the weight...
I thought this video was going to talk about the properties of crystals on a spiritual level
This is a popsci channel, not an esoteric pseudoscience one.
I get crystal but How did you get that from “solar panel”?
I wonder if the comment I wrote about a certain factory in a certain country a few minutes ago will be visible to anyone
Maybe it'll be cost efficient to use as a spray-on coating for solar panels you reapply every couple months. Sans lead.
If light breaks it down, how can it work?
It doesn't break it in an instant, degradation process is slow.
Hey! I didn't get rick rolled. 30% eff cheap solar is terrific. If they take the path of OLED, it's an up hill struggle but it will probably pan out eventually. The OLED story is almost the same story functionally and it is still being told.
Just ripped of JL mother box huh, seeker?
Getting closer to becoming Atlantis
2:47 lolol
free energe generator - is a key piece of most plans
for a carbon neutral energy future
Thank whoever made the pyramids for this discovery
Sounds like you would wanna use them to charge from heat itself
Yes, perovskites can be tuned to absorb in the IR spectrum. You can even create a pure perovskite tandem device that captures both visible and IR light.
Interesting.
Hello solar roadways 2.0 haha
The various teams working on these technologies aren't a couple of jokers working out of a pole barn spending the majority of their time working on promotional content. Infact these teams are working against and in concert to develop stable chemistries as well as determine the most commercially viable multi junction (mixed chemistry) options. Based on the research I've been following, it's a question of when and not if. arxiv.org/search/cond-mat?query=Yan%2C+YAnfa&searchtype=author&abstracts=show&order=-announced_date_first&size=50 for example
When are solar panels > 90% efficient? Maybe it was cheap then and solar panels were a common sight.
So what if we coated it with graphene???
Was looking for this comment
Graphine?
El futuro es hoy...
All of a sudden prehistoric monuments made out of granite filled with Crystals being made “ancient power stations” don’t seem to be as daft as I once thought.
I’m not a whack job I promise... 👀
solution: genetically modify snails to excrete Perovskite crystals and place them on a conductive surface with food source on either side...
30% is a lot... and it's free.
The music in this one is a little disruptive to the speech.
I didn't even not the music lol. U must be really sensitive
The gating ("pumping" effect) on that first one is particularly annoying. Why so many content creators have to put music behind every single informative video is beyond me, and it prevents me from playing my own background music, that isn't objectively complete auditory shite.
@@Medabee8 It's one of those things where, once you notice it, you can't go back to ignoring it. People with hearing problems will have a harder time filtering out relevant audio (in this case, just foreground speech). This also goes for people who are challenged in the focus department. You might experience that yourself when you're very tired.
A solar cell sensitive to light a oxymoron paradox
so, they are only useful in pace which still has the light issue, which is ironic
The Golden Gate Bridge is painted every year so what if...
This dude looks and sounds like he’s of close relation to Mikey Day on SNL.

What is this comment section lol
Solar panels are weak when in light
Every 60 second a minute passes in africa
Pity that many poor souls won't get to fulfill their need to know Mr. Whitaker's phone number - y'know, to get the latest scoop on perovskite tech trends, and stuff...
Your sound quality during the pandemic really didn't go well. I hate to hear compression artifacts on your voice. Can you please solve that issue?
A solar panel that breaks down because of light is Literally ironic
Nice
Its a big scam, Shell already produced panels with an efficiency in 23% at 1/5th the cost. It's kept off the market and people are told it holds promise, to not destroy the cashflow and energy consumption from convential silicon panels.
Hemp Nanotechnology is the answer
APRIL FOOL'S!
Build them in space, and lets develop more nuclear power plants.
I've been in close proximity to lead my entire life and I'm just fime.
That doesn’t change the fact that it’s a toxic element.
Almost sounds like an April mop to me..
Is it bad that upon hearing about advancing solar tech, I immediately feel joy at the thought of oil companies struggling?
Lol... define your version of "struggling". 😆
@@megamanx466 they have to start thinking about buying some more politicians 😆
Yes, oil companies are not evil. It was a necessary stepping stone in our technological advancement that reduced our reliance on coal. I'm sure one day people will be complaining about big solar.
@@Distress. Except.......they buy “Green” patents, sit on them for decades, and prevent new companies from advancing greener technology
@@Distress. Honestly it's human greed that is evil and is typically found in most of us unfortunately.
I do wish oil companies would quit resisting though! 😅
