Cadmium telluride photovoltaics (CdTe PV) is a special type of solar panel that uses special materials to capture the energy from the sun and turn it into usable electricity. The special material is called cadmium telluride. It's made up of two elements, cadmium and tellurium, which form tiny tiny crystals that can absorb the sun's energy when it's sunny outside. The crystals then turn the energy into electricity, which can be used to power homes, businesses, and other things that need electricity. CdTe PV is a great way to use nature's natural energy to generate electricity without causing pollution.
