· CsBiS2

CsBiS₂ is a ternary chalcogenide semiconductor composed of cesium, bismuth, and sulfur, belonging to the class of metal chalcogenide compounds with layered crystal structures. This material is primarily of research and development interest for optoelectronic and photovoltaic applications, where its direct bandgap and strong light-absorption properties make it a candidate for next-generation solar cells and photodetectors as an alternative to lead-based perovskites and conventional silicon devices. The material represents an emerging class of lead-free, environmentally benign semiconductors that offers potential advantages in stability and toxicity compared to established semiconducting systems, though commercial deployment remains largely in the investigational phase.

Export Control

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.
