Cadmium telluride

Description:
Cadmium telluride (CdTe) is a binary compound composed of cadmium and tellurium, classified as a semiconductor material. It has a crystalline structure, typically adopting a cubic zinc blende form, and exhibits notable properties such as a direct bandgap, making it highly efficient for applications in photovoltaic cells. CdTe is characterized by its high absorption coefficient for visible light, which allows for thin-film solar cells to be produced with minimal material usage. Additionally, it has a relatively low melting point compared to other semiconductors, facilitating easier processing. However, cadmium is a toxic heavy metal, raising environmental and health concerns regarding its use and disposal. CdTe is also utilized in infrared optics and radiation detection due to its sensitivity to infrared radiation. Its electrical properties can be modified through doping, enhancing its conductivity and performance in various electronic applications. Overall, while CdTe presents significant advantages in energy applications, careful handling and regulatory measures are essential due to the toxicity of cadmium.
