· Cu3SbS4

Cu3SbS4 is a quaternary semiconductor compound composed of copper, antimony, and sulfur, belonging to the class of sulfide-based semiconductors with potential for optoelectronic and thermoelectric applications. This material exists primarily in research and development contexts, where it is investigated as a candidate for photovoltaic absorber layers, thin-film solar cells, and thermoelectric devices due to its tunable bandgap and earth-abundant elemental composition. Engineers consider Cu3SbS4 as a promising alternative to lead-based perovskites and other toxic semiconductor systems, particularly for cost-effective, scalable energy conversion technologies in emerging markets.
