Recently, Ag-Bi based materials are showing much interest as a low-toxic and inexpensive lead free material to substitute for lead halide perovskite. In this study, III-V cation which is substituted for Bi was researched by time-resolved microwave conductivity (TRMC), not only Ag-Bi based materials. Subsequently, we fabricated solar cell which is made of Sb and Bi mixed films. That solar cell shows higher PCE than Bi single film. To clarify the obtained results, the crystal structure and band levels were investigated. We also report on the result of searching of other metals.
