· JVASP-119102· Ga5CuSe8

Ga5CuSe8 is a quaternary semiconductor compound combining gallium, copper, and selenium—a member of the I-III-VI2 family of materials. This is a research-stage material rather than an established commercial alloy, studied primarily for its potential in photovoltaic and optoelectronic applications where tunable bandgap and light-absorption properties are valuable. The copper-gallium-selenide system is of interest as an alternative absorber layer in thin-film solar cells and as a candidate for infrared detectors, offering potential cost and performance advantages over conventional III-V semiconductors in certain spectral ranges.

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.
