· CuGa2S3.5

CuGa₂S₃.₅ is a copper-gallium sulfide semiconductor compound belonging to the I-III-VI₂ family of ternary chalcogenides. This material is primarily of research interest for photovoltaic and optoelectronic applications, where the tunable band gap and potential for thin-film solar cell architectures make it an alternative to conventional CIGS (copper indium gallium selenide) absorbers. The sulfide composition offers potential advantages in processing temperature and material abundance compared to selenide-based counterparts, though the material remains largely in development stages rather than established industrial production.

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.
