Reversible hydration of CH(3)NH(3)Pbl(3) in films, single crystals, and solar cells [PDF]
, 2015 Solar cells composed of methylammonium lead iodide perovskite (MAPI) are notorious for their sensitivity to moisture. We show that (i) hydrated crystal phases are formed when MAPI is exposed to water vapor at room temperature and (ii) these phase changes
