This is a most excellent place for technology news and articles.
Given that the first perovskites studied had lifespans that could be measured in minutes, this is great progress, but the fundamental problem is that as a class of materials they just don't want to exist outside of an inert atmosphere. Without significant progress in stability and encapsulation materials, they're more of a research curiosity than a viable real-world PV tech.
