Abstract: A new facile method for the synthesis of mixed-cation halide R2 = 0.9935 perovskites based on the chemical conversion of solid precursors (organic halides and lead halides) via an iodine-mediated transport reaction in inert liquid media under mild conditions is described. The equilibrium nature of the conversion provides an exact match between the stoichiometry of the resulting perovskite powder and the molar ratio of the precursors. This method can serve as a useful tool for the synthesis of complex perovskite precursors and the investigation of phase equilibria

Keywords: hybrid halide perovskites, polyiodides, solid solutions, solid phase equilibria, perovskite photovoltaics.
