· Cd2 Te2

Cadmium telluride (CdTe) is a II-VI compound semiconductor formed from cadmium and tellurium, notable for its direct bandgap and high absorption coefficient in the visible to infrared spectrum. It is widely used in photovoltaic solar cells and gamma-ray/X-ray detectors, where its ability to convert photons efficiently into electrical signals makes it superior to silicon-based alternatives in these specific applications. CdTe's popularity in radiation detection and thin-film photovoltaics stems from its optimal bandgap energy and strong interaction with high-energy photons, though toxicity concerns and manufacturing complexity limit its use compared to less toxic semiconductor alternatives.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
