· Cu0.15Ga1.85Se2.85

Cu0.15Ga1.85Se2.85 is a quaternary semiconductor compound belonging to the chalcopyrite family, formed by controlled doping of gallium selenide with copper. This material is primarily investigated in research and development contexts for photovoltaic and optoelectronic applications, where the copper substitution modifies the bandgap and electronic properties compared to binary or ternary selenides. The compound represents an emerging approach to tuning semiconductor characteristics for specialized detector, solar cell, or light-emitting device designs.
