Thermally Driven Reorganization of Polytypic PbI2 Precursor Films Improves MAPbI3 Formation and Crystallization

Abstract Despite rapid progress in solution-processed MAPbI3, the role of PbI2 polytypism in two-step conversion remains largely unexplored. Here, we show that thermally driven reorganization of polytypic chemical-bath-deposited PbI2 thin films influences the subsequent formation...
