Thin-film PV modules are often made out of amorphous or chrystalline silicon, but cadmium telluride, gallium arsenide and copper indium gallium selenide are also used. In the manufacturings process, a thin film of the chosen material is vapor-deposited onto the carrier material. Thin-film modules are recognizable by their uniform surface and the pinstripe pattern. Due to their lower efficiency and low costs, thin-film modules are often used for larger areas. Buy your aSi, CdTe, CSG, CIS or CIGS modules now on the SecondSol marketplace.
