Photovoltaic inverter cadmium telluride

CdTe PV modules provide a beneficial and safe use for cadmium that would otherwise be stored for future use or disposed of in landfills as hazardous waste. Mining byproducts can be converted into a stable CdTe compound and safely encapsulated inside CdTe PV solar modules for years.OverviewCadmium telluride (CdTe) photovoltaics is a (PV) technology based on the use of in a thin layer designed to absorb and convert sunlight into electricity.
