Ga5CuSe8
metal· JVASP-119102· Ga5CuSe8
Ga5CuSe8 is a quaternary semiconductor compound combining gallium, copper, and selenium—a member of the I-III-VI2 family of materials. This is a research-stage material rather than an established commercial alloy, studied primarily for its potential in photovoltaic and optoelectronic applications where tunable bandgap and light-absorption properties are valuable. The copper-gallium-selenide system is of interest as an alternative absorber layer in thin-film solar cells and as a candidate for infrared detectors, offering potential cost and performance advantages over conventional III-V semiconductors in certain spectral ranges.
