· JVASP-155397· Cu3SnS4

Cu3SnS4 is a ternary sulfide compound combining copper, tin, and sulfur—a member of the chalcogenide family that exhibits semiconductor or semi-metallic behavior depending on crystal structure and doping. This material is primarily under investigation in photovoltaic and thermoelectric research communities as a cost-effective, earth-abundant alternative to conventional semiconductors; its main appeal lies in potential use in thin-film solar cells and waste-heat recovery systems where toxicity and supply-chain constraints of cadmium or lead-based compounds are concerns.

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.
