Cadmium telluride (CdTe) is a crystalline compound formed from cadmium and tellurium. It is used as an infrared optical window and a solar cell material. It is sandwiched with cadmium sulfide to form a p-n junction photovoltaic solar cell. Size: 100 * 100 * 6 Typically, CdTe cells use a n-i-p structure.
Cadmium Telluride Targets is used as an infrared optical material for optical windows and lenses but it has small application and is limited by its toxicity such that few optical houses will consider working with it. An early form of CdTe for IR use was marketed under the trademarked name of Irtran-6 but this is obsolete. It is also used to make thin film solar cells, accounting for about 6% of all solar cells. The properties that make CdTe superior for the realization of high performance gamma- and x-ray detectors are high atomic number, large bandgap and high electron mobility ~1100 cm2/V·s, which result in high intrinsic μτ (mobility-lifetime) product and therefore high degree of charge collection and excellent spectral resolution. Specifically, production could be expanded by a factor of 1000 to 10000 (estimates vary) before running out of Te.[
