They say they use green solvents, but in the list of materials at the bottom I see Lead Iodide and Cesium Iodide, which doesn't strike me as too green of a thing to use.
Also, the abstract doesn't really make it clear whether the recycling is for complete panels or the "filling" of panels (sorry for the layman's terms). And whether this applies to any Perovskite-utilizing panel or just certain kinds.
But I am generally heartened at seeing thought regarding industrial processes which consider the end of productive life as well. I wish more products were designed to eventually be taken apart and reduced using standard processes, or even per-product processes - rather than the assumption being that more and more stuff is chucked into landfills.
- PaulHoule 2y agoPerovskite solar panels contain lead so you are going to have lead around, the question is if you can recycle the lead or if it goes in the environment.
- bawolff 2y agoWell there is always alternative number 3 - dont use perovskites.

- einpoklum 2y agoIf you need to use ~1.5x more area, but you avoid leaking any heavy metals or similarly toxic materials - I would say that's a win. Of course, there are other parameters to consider.
