semiconductor· Ga1.1Cu0.9Se2.1
Ga₁.₁Cu₀.₉Se₂.₁ is a quaternary semiconductor compound based on the copper gallium diselenide (CuGaSe₂) family, with slight copper deficiency and gallium excess. This material exists primarily in research and development contexts as a candidate for thin-film photovoltaic absorbers, where non-stoichiometry is intentionally engineered to modify electronic properties and crystal defect characteristics. Compared to the stoichiometric CuGaSe₂ baseline, composition-tuned variants like this one are investigated to improve photoelectric efficiency, reduce recombination losses, and enhance device stability in solar cells.
