· Cu2 Bi2 S2 Cl4

Cu2Bi2S2Cl4 is a mixed-halide chalcogenide semiconductor compound combining copper, bismuth, sulfur, and chlorine elements. This material belongs to the family of layered semiconductors and is primarily of research interest for photovoltaic and optoelectronic applications, where the combination of earth-abundant elements and tunable bandgap properties makes it an attractive alternative to lead-based perovskites. Engineers would evaluate this compound for emerging thin-film solar cells, photodetectors, and other light-harvesting devices where non-toxic, solution-processable semiconductors are desired.
