Cadmium telluride is a crystalline compound formed from cadmium and tellurium. It is used
as an infrared optical window and a solar cell material. It is usually sandwiched with
cadmium sulfide to form a p-n junction photovoltaic solar cell. Typically, CdTe cells use
a n-i-p structure.
It is widely used in the manufacture of solar cells, semiconductor material, visible-band
optoelectronic devices, photosensitive drum, laser modulation, visible light detectors,
laser window materials, Infrared two-color detector, photoluminescence,
electroluminescence, cathode-ray emitting material .
