Cadmium telluride (CdTe) is a stable crystalline compound formed from cadmium and tellurium. It is mainly used as the semiconducting material in cadmium telluride photovoltaics and an infrared optical window. It is usually sandwiched with cadmium sulfide to form a p–n junction solar PV cell. WebOptical and electrical modifications of a highly hydrophilic cellulose regenerated (RC) thin film as result of the inclusion in the film structure of cadmium-tellurium covered with mercaptosuccinic acid quantum dot nanoparticles (CdTe-MSA QDs) are analysed. CdTe-MSA QDs nanoparticles inclusion was p …
