Interesting Perwoskite solar cells with high stability

https://www.sciencedirect.com/science/article/abs/pii/S2211285521004080

This group report reasonable sized (a few cm²😉 samples of their perowskite solar cell materials being stable over comparativeley long times. This sounds like really good news, though any commercialization is probably years in the future.

@Ponderable
They up the stability year by year but still, right now I think they deteriorate after 3000 hours or so, not a useful product yet.

We need more like 30 THOUSAND hours of stability to be a viable product.
Even that would be less than 4 years on the roof.
Silicon I believe is good for 20 YEARS, 160,000 hours.

That is what the final product spec needs to be for peroskvites.

@sonhouse

right you are, but there is potential

@Ponderable
Yep, literally thousands of scientists and engineers working full time on this problem.
