Cu₀.₁In₁.₉Se₂.₉ is a copper-indium selenide semiconductor compound, a derivative of the CuInSe₂ family in which the copper content is reduced and indium is slightly enriched relative to the stoichiometric ternary composition. This material is primarily investigated in photovoltaic research, particularly for thin-film solar cell absorber layers where it may offer tuned bandgap and defect properties compared to the conventional CuInSe₂ baseline. The copper-deficient composition is of interest in laboratory and applied research settings for understanding how dopant/vacancy engineering affects charge transport and recombination in chalcopyrite absorbers, though it remains less established in high-volume industrial production than its parent compound.

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.
