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. See more CdTe is used to make thin film solar cells, accounting for about 8% of all solar cells installed in 2011. They are among the lowest-cost types of solar cell, although a comparison of total installed cost depends on installation size … See more CdTe is insoluble in water. CdTe has a high melting point of 1041 °C with evaporation starting at 1050 °C. CdTe has a vapor pressure of zero at … See more At the present time, the prices of the raw materials cadmium and tellurium are a negligible proportion of the cost of CdTe solar cells and other CdTe devices.
