Ba3Sb2S7

Ba3Sb2S7 is a ternary sulfide semiconductor compound composed of barium, antimony, and sulfur. This material belongs to the family of metal sulfides under investigation for optoelectronic and photovoltaic applications, where its bandgap and crystal structure make it a candidate for light absorption and charge transport. As a research-phase compound rather than an established industrial material, Ba3Sb2S7 represents exploration into alternative semiconductors for thin-film solar cells, photodetectors, and other solid-state devices where conventional materials (CdTe, CIGS, perovskites) may be limited by toxicity, cost, or stability constraints.
