· Ga1.7Cu0.3S2.7

Ga₁.₇Cu₀.₃S₂.₇ is a quaternary semiconductor compound combining gallium, copper, and sulfur in a non-stoichiometric ratio, belonging to the family of I-III-VI₂ chalcogenides. This material is primarily investigated in research settings for photovoltaic and optoelectronic applications, where its tunable bandgap and mixed-valence chemistry offer potential advantages over conventional binary semiconductors like CdS or GaAs, particularly for thin-film solar cells and light-emission devices where cost and compositional flexibility are priorities.

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.
