Cadmium Telluride
It plays a critical role of light absorption—hence why a CdTe solar cell is named after it. However, a cell needs more than just the CdTe material to function. In this "thin-film" technology, a thin layer of CdTe absorbs light, which excites charged particles called electrons; when the electrons move, they create an electric current.
