German scientists develop new process for stable perovskites

A team of researchers from Germany’s Martin Luther University Halle Wittenberg has developed a new approach to perovskite cell production, which they say could result in better stability and longer lifetimes. The team also made detailed observation of the perovskite’s formation and decay, which could help to inform further research into high performance solar cells.
