· JVASP-106817· CuPS2

CuPS2 is a copper-based sulfide compound belonging to the metal chalcogenide family, combining copper with phosphorus and sulfur elements. This material is primarily investigated in materials research for electrochemical and photovoltaic applications, particularly as a potential absorber layer or electrode material in thin-film solar cells and energy storage devices. Its mixed-metal-sulfide composition positions it as an alternative to conventional cadmium or lead-based chalcogenides, offering potential advantages in cost, toxicity, and tunability for next-generation semiconductor and catalytic devices.

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.
