APPLICATIONS CdTe is a useful material for solar cells ( Photovoltaic s). It is cheaper than Silicon , especially in thin-film Solar Cell technology, but not as efficient. CdTe can be alloyed with Mercury to make a versatile Infrared Detector material ( HgCdTe ). CdTe alloyed with a small amount of Zinc makes an excellent solid-state X-ray and Gamma Ray detector ( CdZnTe ). CdTe is used as an Infrared optical material for Optical Window s and Lenses . In this application it is sometimes referred to by the trademarked name ''Irtran-6''. PHYSICAL PROPERTIES

Thermal Properties
Optical Properties CdTe is transparent from close to its band gap energy out to infrared Wavelength s greater than 20 µm. The Refractive Index is 2.649 at 10µm. CHEMICAL PROPERTIES CdTe has very low Solubility in water. It is etched by many acids including Hydrochloric , and Hydrobromic Acid , forming (toxic) Hydrogen Telluride gas. Cadmium telluride is commercially available as a powder, or as crystals. It can be made into nanocrystals. TOXICITY Cadmium telluride is Toxic . It should not be ingested, nor its dust inhaled, and it should not be handled without appropriate gloves. Please refer to materials safety data sheets for details.
