Can't but feel perovskite to be a fad no different than DSSCs before. And I say it as someone who's researched them at EPFL in Michael Graetzel's laboratory.

Can't but feel perovskite to be a fad no different than DSSCs before.
And I say it as someone who's researched them at EPFL in Michael Graetzel's laboratory.
I don't think the technology will ever be efficient and most importantly stable as needed.
- nick7376182 2y agoDoes it degrade when hermetically sealed? I thought it was down to moisture and getting it in a double glass would be good enough
- epolanski 2y agoMoisture heat and light all tend to degrade perovskite. Perovskite is a family a materials by the way so many of these issues can be sortened out. I'm overall just skeptic.
- hn_throwaway_99 2y ago> ... heat and light all tend to degrade perovskite. Have no knowledge in this field but if your solar panel material degrades in light that would seem to be an insurmountable problem to me.
- Dylan16807 2y agoFor "tend to", finding a design that avoids it is surmounting it. Or if you get it slow enough.
- choilive 2y agoOutput degrades at about ~1% a year. EOL for a solar panel is typically about 30 years. It will still generate power but if it is a commercial operation then it will likely be in consideration for replacement. I imagine there would be a large secondary market in the future for used but still functional solar panels as utilities and smaller solar farms replace the panels and possibly funneling into the residential market.
- naasking 2y agoThey don't have to be as efficient if they're 100x cheaper and lighter to boot. The stability is really the only issue.
- cmarschner 2y agoAt planetary scale it seems to be quite important not having to replace the whole fleet every few years don‘t you think? Just from a resource perspective this planet shouldn‘t drown in defunct solar panels.
- immibis 2y agoLuckily, they are made of just a few basic, very recyclable chemical elements. Aluminium is fully recyclable. Glass is fully recyclable. Silicon gets purified as part of its manufacturing process. And that just leaves the plastic backing.
- oai_sys 2y agoJust a thought, but recycling glass is extremely energy intensive. https://www.nrel.gov/docs/legosti/old/5703.pdf https://www.nrel.gov/docs/legosti/old/5703.pdf "Recycling of glass does not save much energy or valuable raw material and does not reduce air or water pollution significantly."
- naasking 2y agoYes, that's why I said the stability of perovskites is the only real issue.
