BiCuOS
semiconductor· BiCuOS
BiCuOS is an experimental ternary semiconductor compound combining bismuth, copper, oxygen, and sulfur, belonging to the family of mixed-valence metal chalcogenides. Currently in the research phase, this material is of interest for photovoltaic and optoelectronic device development due to its narrow bandgap and potential for Earth-abundant, non-toxic alternatives to lead-halide perovskites and conventional group IV-VI semiconductors. The BiCuOS system represents an emerging class of materials designed to balance cost, environmental sustainability, and performance for next-generation thin-film solar cells and light-emitting devices.
