CIGS (Copper Indium Gallium Selenide) Sputtering Targets

Copper indium gallium selenide (CIGS) is a thin-film semiconductor material that is widely used in the manufacture of high-efficiency solar cells. The material has a direct bandgap that can be tuned by adjusting the ratio of indium to gallium, allowing for the optimization of its light absorption and energy conversion capabilities. CIGS thin films can be deposited using techniques like sputtering or co-evaporation, enabling the fabrication of large-area and flexible solar modules. The materials high absorption coefficient, good carrier transport properties, and proven track record in commercial solar cell production make CIGS a leading candidate in the field of thin-film photovoltaics. Ongoing research focuses on improving the stability, scalability, and cost-effectiveness of CIGS solar cell technology.
