· In1.65Cu0.35Se2.65

In₁.₆₅Cu₀.₃₅Se₂.₆₅ is a ternary chalcogenide semiconductor compound combining indium, copper, and selenium in a mixed-cation structure. This material belongs to the family of Cu-In-Se based semiconductors, which are primarily investigated for photovoltaic and optoelectronic applications due to their direct bandgap and strong light absorption characteristics. The copper-indium-selenide family represents an alternative absorber material to the more established CdTe and perovskite systems, with potential advantages in stability and scalability for thin-film solar technologies.

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.
