Abstract
The paper presents the study of the optical properties of a thin layer of Cadmium Sulphide deposited on Cadmium Telluride films. CdTe thin films were obtained by vapor phase condensation method with different thicknesses on glass substrates. The optical properties of the deposited films were analyzed by Swanepoel method using transmission spectra. The upper thin layer of CdS was deposited by thermal evaporation method on CdTe thin films. The change of the optical properties of CdS/CdTe heterojunctions were investigated and compared with CdTe thin films. The main optical constants, such as refractive index and absorption coefficient were calculated. Advanced simulations were performed in SCAPS for optimization of СdS/CdTe thin film heterostructures.
