CdSb2Se3Br2 is a mixed-halide cadmium chalcogenide semiconductor compound combining antimony, selenium, and bromine in a layered or three-dimensional crystal structure. This is a research-phase material primarily investigated for optoelectronic and photovoltaic applications, where the mixed halide composition offers tunable bandgap and enhanced light absorption compared to single-halide alternatives. The material family is relevant to next-generation solar cells, photodetectors, and radiation detection devices where cadmium chalcogenides provide high atomic number sensitivity and favorable band alignment.
