Are perovskite cells a game-changer for solar energy?

[@DWPlanetA]

Do you believe that perovskite technology holds the key to revolutionizing the way we harness solar energy?

[@gregvanpaassen]

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.

[@mitchellmartin4580]

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.

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.

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.

[@eatcochayuyo]

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.

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.

[@Triro]

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.

[@adr2t]

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.

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.

[@Paulo44.01]

Right, was annoyed at the implication that silicon is rare or something

[@flutieflambert]

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.

[@pillington1338]

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.

Need to discuss the lead. How to prevent lead contamination of the environment when these break or wear out?

[@Energy-Americas]

There are tin-based Perovskites as well as lead-based. They are a little less efficient, yet can still compete, it seems, with silicon.

[@Artyomi]

I think it would have been extremely important to point out that the maximum theoretical efficiency of a single junction PV cell is only 33.7% - so getting a similar or higher efficiency than that is extremely ground breaking. For a lay person, seeing that solar PVs are commercially only 20-25% seems very inefficient, and the new breakthroughs only increasing by a few percentage points might seem underwhelming if you don’t consider that this is on the edge of what’s physically possible. It’s like telling someone your car’s engine is only 37.5% efficient, and new engines have reached 46% efficiency - it sounds like almost no progress had been made, meanwhile it’s really gone from 75% to 92% of the maximum possible efficiency. Also to note on that figure, the maximum does increase with the number of layers so getting above that 33% efficiency is not breaking physics or anything - the theoretical maximum of a two layered cell is 42%, so getting an efficiency of 35%-40% is incredible and cannot be understated. For reference, if you keep adding layers, like 3 layers the efficiency goes up to 49% with diminishing returns - if you have infinite layers you can in theory capture 86%, but in reality the best we may be able to get to is 60% in the lab, and 50% commercially.

[@TheRealAfroRick]

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.

[@yp77738yp77739]

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.

[@daemenoth]

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.

[@hugoricogutierrez2402]

Would not support it until lead is replaced. In the video it is mentioned that other material can be used, but not a single option was given, even when precautions were used entering the lab acknowledging the dangers of lead. It may be a future option if this issue is solved.

[@erfquake1]

"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.

[@danilooliveira6580]

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.

[@john_doe_not_found]

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.

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...

[@markjmaxwell9819]

I remember when twenty five percent efficiency and a genuine twenty five year lifetime was considered unattainable. So perovskite catches more of the visible spectrum of light which can be converted to electricity compared to mainly infrared light being caught and converted by silicone panels. This increases the efficiency but at the cost of longevity. So tandem cells solve this problem or double or dual layered panels could also be designed to capture more of the visible light with a layer of both types of technology used. So twenty five years plus lifespans with twenty five percent plus efficiency has been achieved. Most of the current technology we have been striving for such as solid state batteries have been achieved. The best and most economical way to manufacture these breakthroughs is the major hurdle at the current time it seems. 😎🇦🇺👍

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.

[@NNokia-jz6jb]

[@paulgracey4697]

In my humble opinion, only the tandem perovskite cells with silicon stand any chance in the long term marketplace. This is because over time the buyer will only have the silicon cells left to produce energy. If the sealed perovskite cells were never exposed to weather, or other variability of temperature over time, perhaps they can find an indoor use of some sort. I believe this based on a personal experience. Dozens of years ago I bought a small solar array for experiment purposes in my back yard . They were sold by a discount retailer specializing in cheap goods mostly made in China for the firm. In less than two years, here in California, (a more benign weather environment than Germany) I had no output at all from the panels. And when perovskites became a topic on the web solar resources I use, I realized that these were not silicon. Knowing from my work on spacecraft for NASA that they were also not any of the very rare and expensive elements used for tandem cells on government spacecraft, I deduced that they had to be perovskite. The retailer now only sells silicon PV panels.

tl;dr: So perovskite is promising because it is not made out of silicon that needs high temperature to manufacture, but lower.

Is it cheaper than old solar ?

[@DWPlanetA]

Hey there! Yes, they are expected to be cheaper. How much is not sure as they are not yet commercially available and it also depends on the question of degradation.

[@shiekskywalker4269]

Your video which i watched is so good.

[@peterloos1]

Do you have follow-up video's planned for this issue?

[@catcat7835]

Buying now a PV, will require you to recycle it in 30 years as degraded. ROI is 7-10 years. 1 decade to pay itself, second decade to save the money for purchasing the replacement and third decade to finally get "free" electricity. Don't forget about the costs of manufacturing and recycling.

lets go using this video for my chemistry assessment

[@gropatapouf5998]

I wonder why they don't use the silicon layer to protect the perovskyte layer

[@jackofall2305]

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

The inventor of the Perovskite solar cell is a Japanese professor named "Tsutomu Miyasaka".

電気の国家資格を持った日本の技術者です。 このように有望な発電が出てきた一方、今のままではCO2の大きな削減には繋がらない現実も考えなくてはいけない。 何故か？、太陽光発電は曇ると出力が低下する不安定な発電、そのため安定した電力供給を補うのに大型の火力発電がベース電力になっているからです。 春や秋の晴天の日、大手電力会社はメガソーラーに出力制限を要請しています。（夏は暑さでパネルの効率が下がるので未だ制限は掛けられていない） だが解決策は有る、太陽光の余剰電力で重力発電にエネルギーを貯める事と、夜間のエアコン消費を減らす事です。 北欧だったか重力発電は既に出来ているようだが、あの方式よりもっと個数を分散してビルの建屋におもりをコンベアでストックする方式が必要。 この方式にすれば災害などで火力発電が停止した時は、地上に降りたおもりをフォークリフトで2階に運べば発電は持続し、病院など必要最低限のインフラへ電力を供給する事も可能になる。 （蓄電池は製造時に多大なCO2を排出して寒さにも弱い、停電だと使えて２，３日なので採用不可） 尚、夜間のエアコン消費を抑えるには私のサイトを参考に、更に実験してきた他の方法はホームページに記載しているので興味があれば閲覧して下さい。 いずれにしても2030年までに実施出来る方法が必要、北極や南極が溶けるまでに・・

Again, An amazing breakthrough, game changer, revolutionary invention that might change the world as we know it. But we don’t know yet how to make money out of it. Such a template

[@agustinussiahaan6669]

Please cover the Oxford perovskite as well. Thanks.

[@DWPlanetA]

Check out 7:24 of this video - our reporter covers work by Oxford PV ✨

[@hwanin1]

We are in June 2024. Are these product on the market produced by Oxford PV? :)

[@DWPlanetA]

Hey there! They have not started selling yet but according to their website it should happen this year.

[@LucasMakes]

Tell me when degradation is solved. I've known about perovskite for years but we still have the same degradation problem

[@johnransom1146]

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.
