cadmium telluride solar cell, a photovoltaic device that produces electricity from light by using a thin film of cadmium telluride (CdTe). CdTe solar cells differ from crystalline silicon photovoltaic technologies in that they use a smaller amount of semiconductor—a thin film—to convert absorbed light energy into electrons.Though CdTe solar cells are less efficient than crystalline
Cadmium telluride (CdTe) is a stable crystalline compound formed from cadmium and tellurium. It is mainly used as the semiconducting material in cadmium telluride photovoltaics and an infrared optical window. It is usually sandwiched with cadmium sulfide to form a p–n junction solar PV cell.
Cadmium Telluride thin film solar cell is very suitable for building integrated photovoltaics due to its high efficiency and excellent stability. To further reduce the production costs, relieve the scarcity of Tellurium, and apply in building integrated photovoltaics, ultra-thin CdTe photovoltaic technology has been developed.
