Just yesterday I was discussing this issue with my wife. Here we have "Physical Education" in schools, which is mostly kids doing exercises or some kind of sport activity in school, a couple of hours per week. This is surely fine, but I'd also like kids being taught the right way to eat, things to avoid, things to limit... I think it would be an investment for the future, which could avoid a lot of problems related to bad eating habits.

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 I have to admit I haven't worked on perovskite since then, so my knowledge is surely very outdated.

No idea.

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

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.

Yes, https://en.wikipedia.org/wiki/Methylammonium_lead_halide

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?

I choose the highway.

Apple "opinion" -> discarded.

Thanks, I hate it.
