Thin film solar modules are made using thin layers of semiconductor materials deposited onto a substrate, such as glass, plastic, or metal foil. Common semiconductor materials used in thin film solar cells include amorphous silicon (a-Si), cadmium telluride (CdTe), and copper indium gallium selenide (CIGS). Thin film solar cells are typically manufactured using deposition techniques such as chemical vapor deposition (CVD), sputtering, or evaporation. These techniques allow for the deposition of thin layers of semiconductor material onto a substrate, resulting in lightweight and flexible solar modules.
