All-inorganic cesium lead halides are promising candidates for improving the stability of perovskite solar cells against decomposition in an ambient environment. Yet they are harder to process from solution and prefer crystallizing in yellow, non-perovskite phase. In this issue of Joule, Jiang et. al. demonstrate a new set of precursors to deposit thick Cs-based perovskite films and stabilize their black polymorph for 40 days without significant degradation.
