· Cu0.4Ga1.6S2.6

Cu0.4Ga1.6S2.6 is a mixed-valence copper gallium sulfide compound belonging to the family of I-III-VI₂ semiconductors, where copper and gallium cations occupy cation sites within a sulfide anion lattice. This material is primarily of research and developmental interest for optoelectronic and photovoltaic applications, particularly as a wide-bandgap absorber layer or window material in thin-film solar cells and photodetectors. The compound's tunable bandgap, derived from the copper-gallium substitution ratio, makes it attractive for engineers exploring next-generation absorber materials beyond conventional CdTe or CIGS technologies, though it remains largely in the experimental stage compared to commercialized alternatives.

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.
