Summary:Silver doped cadmium sulphide thin films were deposited on a polyethylene terephthalate flexible substrate through the chemical bath deposition method varying the silver deposition time. In this study we analyzed the absorbance in the visible range between 430 and 800 nm. The direct band gap was calculated with the Tauc method, yielding values of 2.25 to 2.46 eV. The crystallographic structure was determined by X-ray diffraction. An evolution was observed from the original hexagonal cadmium sulphide pattern to the appearance of characteristic signals of metallic silver. Scanning electron micrographs were obtained to describe the morphology of the films’s surface. Finally, the electric resistivities measured were in the range of 5.0 and 12.1 x 107 Ω cm.
