What is Cadmium Telluride?
Cadmium Telluride (CdTe) is a semiconductor material with a direct bandgap of 1.45 eV, making it ideal for applications in photovoltaics, radiation detectors, and optoelectronics. Its high absorption coefficient allows for efficient energy conversion and detection.
Key Applications of CdTe
- Photovoltaics: Widely used in thin-film solar cells for its optimal bandgap and high efficiency.
- Radiation Detectors: Essential in X-ray and gamma-ray detection systems.
- Infrared Optoelectronics: Key material in infrared detectors and thermal imaging systems.
Cadmium Telluride is a critical material in advancing renewable energy and sensor technologies. However, considerations around toxicity and resource availability are essential for its sustainable use.
