The influence of physical and technological condensation mode by direct current magnetron sputtering on the crystal structure and optical properties of grown CdS and CdTe films, CdS/CdTe thin films heterosystems was investigated. Traditional chloride treatment of thin-film CdS/CdТе heterosystem leads to recrystallization of CdTe basic layer and its wurtzite-sphalerite phase transition. After Cl treatment a bandgap in CdTe increases up to 1.5 eV. For CdS/CdТе heterosystem a decrease of a bandgap to 1.45 eV is observed which is determined by formation of solid solutions of CdSхТе₁₋ₓ at the interphase boundary of CdS/CdТе. The value of the stoichiometric parameter х=0,1±0,01 was calculated using the optical researches data.
