Cadmium telluride (chemical formula: CdTe) is a crystalline compound of tellurium element and cadmium. This semiconductor manufacture of infrared optical window. In addition, cadmium telluride solar cell manufacturing has broad application prospects. In thin film batteries, cadmium telluride is usually sandwiched between two layers of cadmium sulfide materials, this PN junction is called the Pin structure. Cadmium telluride Brown-black crystalline powder. Insoluble in water and acid. Decomposition in the nitric acid. It is mainly used in manufacturer of CdTe thin-film solar cells. Spectroscopy. CO2 laser Q modulation.
Cadmium telluride is used for the production of solar cells, infrared modulator, the HgxCdl-xTe substrate, the infrared window electroluminescent devices, solar cells, infrared detection, X-ray detection, nuclear radioactivity detector, close to the visible light emitting devices.
