Usage

Description

Cadmium Telluride (CdTe) is a photonic material with a zinc blende crystal structure. It is a brownish-black, cubic crystal that oxidizes on prolonged exposure to moist air and is insoluble in water and mineral acids except nitric, in which it is soluble with decomposition. CdTe is known for its low cost, direct band gap (1.44eV), and high absorption coefficient, making it an ideal choice for various applications.

Uses

Used in Photovoltaic Applications:
Cadmium Telluride is used as a semiconductor material in the production of thin film solar cells. It is particularly suitable for photovoltaic applications due to its low cost, direct band gap, and high absorption coefficient. CdTe is also used as the window layer in photovoltaic solar cells, as demonstrated in the preparation of an Au/Cu2Te/CdTe/CdS/TCO/glass heterostructure for solar cell.
Used in Infrared Optical Window:
Cadmium Telluride is utilized in the infrared optical window industry due to its unique properties that make it suitable for this application.
Used in Radiation Detectors:
CdTe is doped with chlorine and used as a radiation detector for x-rays, alpha, and beta particles, making it valuable in the field of radiation detection and safety.
Used in Semiconductor Research:
Cadmium Telluride is employed in semiconductor research, where its properties are further explored and optimized for various applications.
Used in Phosphors:
CdTe is also used in the production of phosphors, which are essential components in various display technologies and lighting applications.
