The working principle of CdTe solar panels is based on the photovoltaic effect. This energy creates electron-hole pairs, generating a flow of electrons .
HOME / The principle of power generation of cdte compound solar cells - G01 Smart Energy
Together, the CdTe, intermediate, and TCO layers form an electric field that converts light absorbed in the CdTe layer into current and voltage. Metal is placed on the back to form electrical
CdTe solar cells have achieved a high-power conversion efficiency of 23.1%. To further boost the device''s performance, it is crucial to systematically tune the doping concentration and
In a solar cell, the CdTe absorber is attached to other materials, which allows electric current to flow through the absorber layer into the metal contacts and be collected as sustainable electricity.

Cadmium (Cd), a toxic heavy metal considered a hazardous substance, is a waste byproduct of mining, smelting and refining sulfidic ores of zinc during zinc refining, and therefore its production does not depend on PV market demand. 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 s
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
