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 usually sandwiched with cadmium sulfide to form a p-n junction photovoltaic solar cell. Typically, CdTe cells use a n-i-p structure. Cadmium telluride is toxic if ingested, if its dust is inhaled, or if it is handled improperly (i.e. without appropriate gloves and other safety precautions). Once properly and securely captured and encapsulated, CdTe used in manufacturing processes may be rendered harmless. CdTe appears to be less toxic than elemental cadmium, at least in terms of acute exposure.
CdTe has very low solubility in water . It is etched by many acids including hydrochloric, and hydrobromic acid, forming (toxic) hydrogen telluride gas and toxic cadmium salts. It is a reducing agent and is unstable in air at high temperatures.
Cadmium telluride is commercially available as a powder, or as crystals. It can be made into nanocrystals
