Abstract

Here we report the investigation of controlled PbI<sub>2</sub> secondary phase formation in CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> (MAPI) photovoltaics through post-deposition thermal annealing, identifying the location of PbI<sub>2</sub> in the active layer and its beneficial role on device performance.
