Toward the carrier doping by impurity substitution in metal halide perovskite semiconductors, we fabricated Bi-doped CH₃NH₃PbX₃ (X=I,Br) single crystals. In CH₃NH₃PbBr₃, photoluminescence spectrum shows blue shift by Bi substitution. Resistivity is reduced with an increase of Bi concentration, suggesting that carriers are successfully doped in CH₃NH₃PbBr₃ single crystals. In this talk, we will report details of the optical and electrical properties of Bi-doped CH₃NH₃PbBr₃ and CH₃NH₃PbI₃ single crystals.
