Metal halide perovskite materials have opened up a great opportunity for high performance optoelectronic devices owing to their extraordinary optoelectronic properties. More than lead-halide ones, stable and nontoxic bismuth halide perovskites exhibit more promising in their future commercialization. In this work, we developed for the first time full inorganic Cs3Bi2I9-xBrx perovskites based photodetectors and modulate their performance by varying x in composition systematically. Among those… Expand
