Description : Cadmium Telluride (CAS No: 1306-25-8), positioned across international chemical indices as cadmium monotelluride, 5N photovoltaic grade CdTe, and II-VI compound semiconductor, is driving major advancements across the global solar energy, infrared optics, nuclear radiation detection, and space electronics sectors. Featuring a direct bandgap (~ 1.44 eV) that matches the terrestrial solar spectrum, Cadmium Telluride serves as the premier light-absorbing semiconductor material for commercial thin-film photovoltaic (PV) modules, high-efficiency solar farms, and space-grade power units. The global renewable energy and defence sensor markets are undergoing a multi-billion-dollar strategic sourcing expansion. Thin-film solar module fabricators, defence contractors, and radiation detector OEMs are moving away from variable-purity feedstocks toward strictly controlled 5N (99.999%) CaTe deposition powders, granules, and sputtering targets. Consistently verified chemical stoichiometry and sub-ppm metallic purity prevent recombination centres, maintain high open-circuit voltage (Voc), and maximise solar conversion efficiency during vapour transport deposition (VTD) and close-spaced sublimation (CSS). As a primary global Cadmium Telluride supplier, we deliver 5N high-purity lumps, powders, and sputtering targets complete with Glow Discharge Mass Spectrometry (GDMS) analytical verification, Cadmium Telluride CoA, and Cadmium TellurideTDS documentation across international trade channels.
