· CsInS2

CsInS2 is a ternary chalcogenide semiconductor compound composed of cesium, indium, and sulfur, belonging to the family of wide-bandgap semiconductors used in optoelectronic and photovoltaic applications. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in high-efficiency photovoltaic cells, UV-visible photodetectors, and nonlinear optical devices where its direct bandgap and crystalline structure offer advantages over traditional silicon-based semiconductors. The cesium-indium-sulfide family is investigated as an alternative to lead halide perovskites and CdTe in next-generation solar technologies, particularly for applications requiring improved stability and reduced toxicity.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
