· Ca1 Sn1 S3

CaSnS₃ is a ternary chalcogenide semiconductor compound combining calcium, tin, and sulfur in a layered crystal structure. This material is primarily of research interest as a potential photovoltaic absorber and optoelectronic device material, belonging to the broader family of earth-abundant semiconductors being explored as alternatives to lead-based perovskites and conventional III-V semiconductors. Its appeal lies in the use of non-toxic, relatively abundant elements, though it remains largely in experimental development stages with ongoing investigation into synthesis methods, phase stability, and device integration.

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.
