· CuGaInS3.5

CuGaInS3.5 is a quaternary chalcogenide semiconductor compound combining copper, gallium, indium, and sulfur in a 1:1:1:2.5 stoichiometry. This material belongs to the family of I-III-VI₂ semiconductors and is primarily studied in research contexts for photovoltaic and optoelectronic applications, where it offers tunable bandgap and potential for thin-film solar cell architectures as an alternative or complement to more established compounds like CIGS (copper indium gallium selenide).

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.
