Cadmium telluride (CdTe) is a dark grey crystalline compound, used primarily for its electrical and optical properties. A significant proportion of cadmium telluride used in photovoltaics comes from recycled products, with production costs remaining low despite the relative scarcity of tellurium. It can be difficult to maintain purity in cadmium telluride.



  • Solar cells. The most significant current application of cadmium telluride is the production of thin film solar cells. CdTe solar cells make up about 8% of solar cells installed, offering a low installation and production cost.
  • Detectors. A number of optical detection devices rely upon cadmium telluride alloyed or doped with other elements. Infrared detectors, X-ray detectors, gamma ray detectors, beta particle detectors, and alpha particle detectors all rely upon materials produced with cadmium telluride.
  • Optical windows and lenses. The same properties which make cadmium telluride valuable in solar cell production and optical detection materials make it useful in the production of optical windows and optical lenses. CdTe used for this purpose in the infrared market once went by the trademark Irtran-6, but the name is now obsolete.
  • Electro-optic modulators. Frequently used for its high electro-optic coefficient of the linear electro-optic effect, the highest among similar materials.
