Cadmium telluride (CdTe) is a binary II-VI semiconductor ceramic compound primarily used as a photovoltaic material and radiation detector. It is employed in thin-film solar cells for terrestrial and space applications due to its high absorption coefficient and direct bandgap, and in gamma-ray and X-ray detection systems where its atomic composition provides strong stopping power for ionizing radiation. CdTe is notable for achieving competitive efficiency in commercial photovoltaic modules while maintaining lower manufacturing complexity than silicon-based alternatives, though environmental and health considerations regarding cadmium content influence its deployment in some markets.
