The Use of Cadmium telluride

Cadmium telluride is a crystalline compound formed from cadmium and tellurium. Three major CdTe on glass factories in the US have been recently announced each with a unique starting point. Let’s take a closer look to see which one of these factories might have the best advantage to be in the lead to generate revenue. 
Abound Solar has won a US DOE loan to support a new 640 MW/yr facility in Tipton, Indiana. General Electric (GE) recently announced buying Primestar.
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.
They indicate that they will be building the largest PV manufacturing facility in the world. It is widely used in the fabricate of solar cellular phone, semiconductor device fabric, visible-band optoelectronic devices, photosensitive drum, laser pitch contour, obvious brightness level detectors, laser window materials, infrared radiation two-color detector, photoluminescence, electroluminescence, cathode-ray emitting material.
Finally First Solar has announced a 250 MW/yr facility to be built in Mesa City Arizona near Phoenix.
