Cadmium Telluride (CdTe) is a compound made from the elements cadmium and tellurium. It is primarily used in the production of thin-film solar cells due to its efficient light absorption properties. CdTe is known for its ability to convert sunlight into electricity, making it a popular choice in renewable energy applications. In addition to solar energy, CdTe has applications in semiconductors and photodetectors. Its unique electronic properties allow it to be used in various electronic devices. However, concerns about the toxicity of cadmium have led to ongoing research into safer alternatives and recycling methods for CdTe-based products.
