The point is... (almost) nobody is going to do that. Ask a layman what a SMTP is.

Yes. Talking to myself is sooooo satisfying...

Thanks. I have to admit I haven't worked on perovskite since then, so my knowledge is surely very outdated.

Excuse me, what's STL?

[โ€“] Engywuck@lemm.ee 14 points 3 months ago (10 children)

Now I want that. No, now I NEED that.

[โ€“] Engywuck@lemm.ee 5 points 3 months ago

Yeah, but I'm talking about chemical instability which happens nonetheless, independently on the light you shine on it.

[โ€“] Engywuck@lemm.ee 2 points 3 months ago

No idea. IIRC the problem comes from chemical instability i.e., even when properly encapsulated, the methylammonium just evaporates/decompose and you're left with a nice lead iodide layer. Can't say if it's better now. It's been quite a feew years ago.

I used to work on hybrid perovskite for solar cells, during my PhD, a few years ago. The problem with theses materials was their short lifetime (some thousands of hours of sun exposition) and chemical instability, which made them unsuitable for "real life" uses, back then (but suitable to get high impact-factor papers...). Is that still a problem?
