Cu2 Ga2 Se4
semiconductor· Cu2 Ga2 Se4
Cu₂Ga₂Se₄ is a quaternary semiconductor compound belonging to the chalcopyrite family, composed of copper, gallium, and selenium elements. This material is primarily investigated in photovoltaic and optoelectronic research, where its tunable bandgap and direct semiconductor properties make it a candidate for thin-film solar cells and light-emitting applications. While not yet widely commercialized compared to established alternatives like CdTe or CIGS absorbers, Cu₂Ga₂Se₄ represents a research-stage material of interest for next-generation photovoltaic devices and potentially for infrared detection systems due to its semiconductor characteristics.
