| | CADMIUM TELLURIDE Usage And Synthesis |
| Chemical Properties | Brownish-black, cubic crystals.Oxidizes on prolonged expo-
sure to moist air. Insoluble in water and mineral
acids except nitric, in which it is soluble with
decomposition. | | Uses | Cadmium telluride finds applications as the semiconductor material in photovoltaics and infrared optical window. It is used in the production of thin film solar cells. It is doped with chlorine and used as a radiation detector for x-rays, alfa and beta particles. . | | Uses | Cadmium telluride may be used in photovoltaic solar cells as the window layer. CdTe was used in the preparation of an Au/Cu2Te/CdTe/CdS/TCO/glass heterostructure for solar cell. | | Uses | In semiconductor research, in phosphors. | | General Description | CdTe is a photonic material. Crystal structure of CdTe is zinc blende structure. 3CdTe is usually an obvious choice for photovoltaic applications because of its; low cost, direct band gap (1.44eV),3 high absorption coefficient, easily doped with p and n type dopants by several preparation techniques. 2 | | Hazard | Toxic by inhalation.
