  • Nanostructure-containing organic-metal halide perovskites
    Patent number: 10586657
    Abstract: Described herein is a device that includes an alkyl ammonium metal halide perovskite layer, and a nanostructured semiconductor layer in physical contact with the alkyl ammonium metal halide perovskite layer. The alkyl ammonium metal halide perovskite layer may include methyl ammonium cations. The alkyl ammonium metal halide perovskite layer may include anions of at least one of chlorine, bromine, astatine, and/or iodine. The alkyl ammonium metal halide perovskite layer may include cations of a metal in a 2+ valence state. The metal may include at least one of lead, tin, and/or germanium.
