Solar Progress
Crystal structure discovered almost 200 years ago could hold key to solar cell revolution

Quote:Perovskite cells can be inexpensively manufactured from commonly available industrial chemicals and metals and can be printed onto flexible films of plastic and mass produced. Silicon cells, conversely, are rigid and made from thinly sliced wafers of almost pure silicon in an expensive, high-temperature process.

One issue with perovskites is their tendency to be somewhat unstable when temperatures rise, and another is a vulnerability to moisture—a combination that can make the cells decompose. That's a problem for a product that needs to last two or three decades in open air.
