· Cu0.35Ga1.65Se2.65

Cu0.35Ga1.65Se2.65 is a quaternary chalcogenide semiconductor compound belonging to the I-III-VI2 family, engineered by copper and gallium alloying in a selenium matrix. This material is primarily investigated for photovoltaic and optoelectronic applications, particularly as an absorber layer or window material in thin-film solar cells and photodetectors. The precise stoichiometry suggests experimental research focus on bandgap engineering and efficiency optimization in next-generation solar technologies, where this composition offers potential advantages in light absorption and carrier transport compared to binary or ternary analogues.
