· Ca2 Sn1 S4

Calcium tin sulfide (Ca₂Sn₁S₄) is a quaternary semiconductor compound belonging to the thiospinel family, characterized by a mixed-cation sulfide structure. This material is primarily of research interest for photovoltaic and optoelectronic applications, where its tunable bandgap and Earth-abundant constituent elements position it as a potential alternative to conventional cadmium- or lead-based semiconductors. The combination of calcium and tin cations within a sulfide lattice offers advantages in toxicity reduction and raw material availability compared to established semiconductor technologies, making it relevant for thin-film solar cells, photodetectors, and emerging quantum-dot applications where cost and environmental impact are design drivers.

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.
