· Ga1.01Cu0.99Se2.01

Ga₁.₀₁Cu₀.₉₉Se₂.₀₁ is a quaternary semiconductor compound based on the copper gallium diselenide (CuGaSe₂) family, with near-stoichiometric composition and slight gallium enrichment. This material belongs to the chalcopyrite semiconductor class and is primarily investigated for photovoltaic and optoelectronic applications, where it offers tunable bandgap and potential for thin-film solar cells and photodetectors. While not yet widely commercialized compared to established alternatives like CdTe or CIGS absorbers, this composition is of research interest for its stability, defect-tolerance properties, and compatibility with scalable deposition methods in emerging photovoltaic technology.

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.
