CsSbS2

CsSbS₂ is a ternary chalcogenide semiconductor composed of cesium, antimony, and sulfur, belonging to the family of metal chalcogenides that exhibit layer-structured crystal lattices and moderate band gaps. This compound is primarily explored in research and development contexts for optoelectronic and photovoltaic applications, where its intrinsic semiconducting properties and potential for thin-film processing make it a candidate for next-generation solar cells, photodetectors, and nonlinear optical devices; however, it remains largely experimental with limited commercial deployment compared to more established semiconductors like CdTe or perovskites.
