CdBiSe₂Br is a ternary halide ceramic compound combining cadmium, bismuth, selenium, and bromine—a member of the emerging family of mixed-metal chalcohalide materials. This is primarily a research-phase compound investigated for optoelectronic and photovoltaic applications due to its tunable bandgap and potential for improved stability compared to lead-based perovskites, though industrial deployment remains limited.
