semiconductor· Cu0.5Ga1.5Se2.5
Cu₀.₅Ga₁.₅Se₂.₅ is a quaternary semiconductor compound belonging to the I-III-VI₂ family, structurally related to chalcopyrite semiconductors. This material is primarily of research interest for photovoltaic and optoelectronic applications, where its tunable bandgap and direct band structure make it a candidate for thin-film solar cells, photodetectors, and light-emitting devices. While not yet commercialized at scale, compounds in this family are being investigated as alternatives to conventional cadmium telluride (CdTe) and copper indium gallium selenide (CIGS) absorbers, offering potential advantages in cost, toxicity, and device efficiency through compositional engineering.
