Cadmium telluride is commercially available as a powder, or as crystals. It can be made into nanocrystals. The compound CdTe has different qualities than the two elements, cadmium and tellurium, taken separately. CdTe has low acute inhalation, oral, and aquatic toxicity, and is negative in the Ames mutagenicity test.
But, still there is a lack of comprehensive data bank with regard to the functional parameters of cadmium telluride crystals for energy harvesting applications. The basic knowledge of crystal, physical properties and experimental protocols ease the fabrication of CdTe based transistor as well as solar cell.
