Perovskite and silicon appear to be the dream combo for improved efficiency in solar PV technology, with the potential to more than double the performance of anything you may have on your roof today. If you live in America, you can now buy perovskite/ silicon solar panels manufactured in Europe. So what is Perovskite, how does it work with silicon, and when will you be installing 43% efficient panels for your home?

@agsystems8220 8 часов назад

Energy efficiency only makes sense to talk about if you are running out of space, and we are not nearly close to that. Far more important is cost per watt, including installation. More efficient cells are more compact, so less installation for the same power, but it doesn't matter if the cells are not cost competitive. The most important question is whether a technology can be cheap.

@jantjarks7946 5 часов назад

Installation costs are a massive part of the overall costs though. Both have to be weighted against each other. As usual, a new technology costs more, with declining costs over time. All that has to be taken into account.

10% efficiency loss after 600h of sunlight is still terrible in comparison [EDIT: I understood the numbers incorrectly - see below. It was actually only 3% loss] to the established silicon panels. That´s less than a very cloudy year. So, after 2 years the panels become less efficient than conventional ones, after 4 years their lifetime production is down below what conventional panels produced so far and by then, they are essentially e-waste and have to be replaced (all assuming, the degradeation is linear), whilst conventional panels will be good for 15+ years. The development of the technology is still impressive.

@mael1515 6 часов назад

I agree, but as I understood it, the degradation is only for the perovskite part of a tandem module. So the silicone part should stay the same 🤔

@FischerNilsA 6 часов назад

But...material degradation isnt linear in any given example. Let alone solar panels. Current standard silicon panels start out loosing 2-4% in the first year, with the capacity loss getting smaller each year after that.

@martinhuhn7813 6 часов назад

@@mael1515 As I understood it, most of the video was about pure perovskite panels which are on sale now, whilst the very highly efficient tandem module was rather something for the future. That being said: I am not sure, if the silicone part will really be unaffected, when the perovskite part degrades. I can imagine some reasons, why that might not be the case. But it would be more usefull if somebody without more knowledge about the technology than me addressed that question.

@martinhuhn7813 5 часов назад

@@FischerNilsA Sure, I don´t know, how the degradation of perovskite panels develops. It might slow down as it does for silicone based systems, continue linear or even accellerate dramatically. That´s the problem with insufficient data. The video did not tell us about the dynamics of the degradation. And if 600h of continuous sunlight are mentioned, that does not even tell us anything about ageing over time (independant of the light) or the effects of temperature fluctuations in the real world or the effect that changes in light exposure in comparison to continuous exposure might have.

@justin_time 16 часов назад

40% efficiency solar cells would definitely make solar electric vehicles much more viable for lots of folks out there. Right now it seems that the typical range gain from adding solar cells to a vehicle is about 10-20 miles per day, but doubling current efficiency would bring it up to 20-40 miles per day, which I believe would cover most people's commutes. Very hope inspiring tech. I'm glad to hear that this one actually came to fruition. I hope the technology continues to improve too.

I read many concerns about the longevity of perovskite panels, but if they are dirt cheap, that might not be much of an issue.. just have them removed and install new ones (which are probably better as well), the old ones should then be recycled, so the materials can be used to make new solar panels.

@ristekostadinov2820 16 часов назад

I hope development continues because they are certainly viable for specific applications. But even if their reliability is improved, I doubt they will ever reach the amazing reliability and manufactured cost of current solar cells whose prices are still falling. Three problems: Their manufacture requires adding additional layers which requires a more complicated and expensive manufacturing process. These additional layers decrease the cell's thermal conductivity which complicates cooling issues. Their weather-resilient protection requires more expensive UV transparent glass or a plastic that is as durable glass.

The description of what happens when the sunlight hits the material reminds me of batteries.

I am not sure if that is correct just my thoughts. The silicone panel probably work very different but they also eventually decay in the sun too. I say this because I live in Florida and the sun is very strong here. I like experiments with solar technologies to try to optimize efficiency for example here in Florida having a way to cool a panel improve thier efficiency a lot. They also can last a bit longer although the sun eats them away eventually. Said to much. Great video thank you 😊

recyclability is not really that important, specially if it's at the cost of panel durability. modern solar panels are made to last more than 30 years already, and even after 30 years they still produce plenty of energy. if you can make them easier to recycle without affecting durability, then sure, but modern panels already can be recycled, it's just a lot more expensive then mining new raw materials. but it would be even better if we found ways to continue using old panels, just like we should find ways to continue using old batteries for as long as they still work.

@incognitotorpedo42 16 часов назад

No, that's not "all that matters". When you're comparing it to coal as a source of electricity, you need to consider all the people and other animals getting sick or dying from the air pollution, the mountains of toxic coal ash, the massive, ongoing destruction of the environment while we continually mine massive quantities of coal. With solar panels, the material requirements are minimal. Infinitesimal, in comparison to coal. At the end of their useful life, decades in the future, they can be harmlessly buried. So what. I know, "Reeee, it's not 'sustainable'!!!" BFD. Coal is killing us.

@@incognitotorpedo42They are easily modified into standard roofing material. But yes, burying them in landfills is easily justified because their 30-year lifetimes make their mass per year relatively low. Orders of magnitude lower than most anything else you put in a landfill. Add another order of magnitude or two when you consider single use plastic and don't even get me started on disposable diapers and kitty litter...

What about lifetime energy? Longevity was a problem with perovskites

@AlfaStation1 3 часа назад

Nice but how much of these new panels can be recycled? Traditional solar panels can be recycled for 98%. I'm guessing these P panels will need special glass which might make them impossible to recycle alltogether! 😢

"In addition, encapsulated devices display excellent operational stability by retaining over 97% of their initial performance after 600 h continuous illumination". 600 hours is 25 days. If you assume continuous illumination in the real world of roughly 12 hours a day, you's still only looking at 50 days for the cells to drop 3% efficiency. Not exactly ready for the real world based on that one statistic, would need to see if the degradation was constant or whether the cell efficiency reached some form of stability.

@alexogle8950 Час назад

OK, let's "Just Have a Think"... The chemical used to improve the surface flatness contains thionyl and fluorine, both of which are extremely toxic and difficult to recover and recycle. Then, the longevity was advertised as a 3% reduction in efficacy after continual illuminaton for 600 hours (how bright/aggressive was this illumination?). That's 50 days. If we take the approach that every 50 days will cause 3% degradation then the treatment will be 50% effective after only 3 years. I know there is room for 'development', but the cheeky, chirpy, attitude of this video in amplifying the work of a Chinese group that has made a discovery when China as a whole is committed to increasing coal consumption for power is what's really causing me to "Just Have a Think".

@MrAdopado 5 часов назад

They are not on general sale in the USA according to other comments here so presumably they are first going to commercial investors, those who put up some of the money to make the cells/panels.

This polyfluorinated coating sounds a bit like another one of those "forever" chemicals. Any thoughts?

@incognitotorpedo42 14 часов назад

That's a legitimate question. I found the paper and looked at the structure. It's only a trifluoromethyl, so not the perflourinated species (like perfluorooctanoic acid/PFOA) that people are concerned about. PFOA is very hydrophobic and has 15 fluorines, while a trifluormethyl is not very hydrophobic and has only three fluorines. Trifluoromethyl groups appear in a some pharmaceuticals, so they've been studied in great detail as part of the drug approval process.

33.9% is verified. however what the japanese competitor speculate they can compete against the chinese panel by maximising lifespan of their products; claiming their product can last longer. i am not sure if the japanese path of focusing on lifespan is better than efficiency... since that just mean slow ROI for the buyer... but it is interesting to see how they are trying to avoid direct competition with their chinese counterpart.

If 600 hours is guaranteed - that's not much compared to 25 years guarantee from others. In the end € £ $ per watt matters, and so does guarantee or warrantee

Ah, remember the days when the naysayers couldn't let go of how "inefficient" solar is? Remember when they said it was a waste of funds (no matter government or personal)? It's almost like there was some kind of threshold that needed to be passed in order to achieve viability at scale....

@guciolini123 Час назад

We do know that Perovskite are (to say the list) no more durable then silicon. This means those panels will end their life span soon. What about them after this? Is there any not hazardous to environment way to get rid of them? Also I hope this tech (if it gains traction) won't cause trashing working silicon panels before time. Remember- repair and reuse is always the most ecological and (in a normal world) economical way! Cause of government subsidies it can be sometimes less costly to buy new stuff, but it shouldn't be this way.

3% degradation over 2 months doesn't sound that great doubling the efficiency while needing to replace the panels twice/thrice as often is not exactly optimal, think we might need to see much more progression on the longevity front for this to be a game changer seems like a viable solution for installations on limited real estate where conventional panels can't reach the desired output

@riveness 10 часов назад

Sounds like a slightly better degradation rate than what we were achieving in ecn/tno at that efficiency point 15 years ago.

Not sure how it is where you are but in the countries I've lived in you can always go to your local university and enter as a visitor and access pdf copies legally for free. I currently have university access but I used to do this occasionally to get access to journals my university didn't subscribe to.

Considering the time that it might take Dave to get to the nearest university, it might be worth his while to pay for a copy. It depends on the cost of getting to the Uni and back, versus the value of your time.
