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.
