· Ga1.5Cu0.5Se2.5

Ga₁.₅Cu₀.₅Se₂.₅ is a quaternary semiconductor compound combining gallium, copper, and selenium in a non-stoichiometric ratio, belonging to the family of chalcogenide semiconductors. This material is primarily of research interest for photovoltaic and optoelectronic applications, where mixed-valence copper-gallium selenides are explored as absorber layers or buffer materials in thin-film solar cells and photodetectors. While not yet widely commercialized, this composition family is investigated as an alternative to conventional cadmium-based or all-inorganic perovskite absorbers, offering potential advantages in bandgap tunability and earth-abundant element content, though synthesis control and stability remain active research challenges.

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.
