CuSeS
metal· JVASP-119194· CuSeS
CuSeS is a ternary copper selenide sulfide compound that belongs to the family of mixed-anion chalcogenides. This material is primarily of research interest for semiconductor and photovoltaic applications, where the combination of copper, selenium, and sulfur creates tunable electronic properties for light absorption and charge transport. Industrial adoption remains limited, but the material shows promise in thin-film solar cells and thermoelectric devices as a lower-toxicity alternative to lead-based or cadmium-based semiconductors.

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.
