Description
Cadmium telluride (CdTe) is a stable crystalline compound formed from cadmium and tellurium. It is used as an infrared optical window and is a highly efficient solar cell material with lowest-cost types of solar cell. CdTe has many merits, such as expected bandwidth, Absorbance and Conversion efficiency whilst it is safety and low cost. Santech Materials is committed to producing CdTe powder/target and aim to be a leading premium supplier of specialty materials in China.

    
Applications
1.Thin film solar cells
2.An infrared optical material for optical windows and lenses
3.Electro-optic modulators.
