Multi-layered perovskites, devices, and methods of making the same

Abstract:

Methods are described that include contacting an alkyl ammonium metal halide film with an alkyl ammonium halide, where the alkyl ammonium metal halide film includes a first halogen and a metal, the alkyl ammonium halide includes a second halogen, such that the contacting forms an alkyl ammonium metal mixed-halide film that interfaces with the alkyl ammonium metal halide film, where the alkyl ammonium metal mixed-halide film includes the first halogen, the second halogen, and the metal.
