WebAll‐inorganic perovskite cesium lead triiodide (CsPbI3) has attracted much attention among the perovskite family due to its excellent optoelectronic properties and chemical stability. WebIn fact, perovskite readily transforms to monohydrate phase MAPbI 3 ∙H 2 O in moderate humidity (RH < 60%), and to dihydrate phase (MA) 4 PbI 6 ∙2H 2 O in high humidity (RH > 80%). This can be explained by the fact that the hydrogen bonding interaction between the lead iodide framework and organic MA + cations is weakened by hydration. As a result, …
