The thin-film photovoltaics, solar thermal, and concentrated solar power systems offer great alternatives for the future's energy requirements. Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous and also other thin-film silicon (a-Si, TF-Si).  A copper indium gallium selenide solar(CIGS) cell uses the absorber made of mentioned elements in the name. At the same time, gallium-free variants of the semiconductor material are abbreviated CIS. It is one of three mainstream thin-film technologies, with a lab-efficiency above 20 percent and a share of 2 percent in the overall PV market in 2013. Traditional fabrication methods involve vacuum processes, including co-evaporation and sputtering, and rotary magnetron sputtering technology is used in all primary forms of solar cell technology. High-grade materials must be sourced for the improvement of solar system efficiency.
