A simple and cheap method has been developed for the deposition of cadmium telluride thin films on glass substrates by pulsed Nd:YAG laser eva poration of cadmium telluride pellets prepared from h igh purity Cd and Te powders. Preliminary characterization of the crystallographic, electrical and optical properties of the films has been performed as a function of the deposition conditions (pellet constituent percentage of pelts Cd/Te ≤ 1.0 and Cd/Te 1.0). Both deposition temperatures and nitrog en pressure during deposition have been considered. F rom transmittance and reflectance measurements, the values of th e absorption coefficient α, of the band gap Eg, have been calculated.
