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.

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.

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.

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.

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.

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.

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

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.

Thanks for reuploading the old video.

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.

Its decomposes super fast in humidity

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...

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.

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.

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.

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.

"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.

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. ..
