- Abstract
This process of this paper is carried out using the chemical spraying method to produce homogeneous thin films of pure cadmium sulfide-doped with silver at different percentages of 1%, 3%, and 5% on glass and polyimide plastic substrates at 300°C. The aim is to study the optical and structural properties of the samples and the effect of the silver doping rate on films produced with these properties. Due to X-ray diffraction studies, all films created had a hexagonal phase, and it was noticed that they had a very precise structure free of holes or cracks. The obtained crystal size ranged between 22.74 nm and 55.05 nm for different substrates, and the prominent plane was (002). From the optical properties, all films exhibited transmission higher than 60%, thus showing a low absorption, which makes them be used as light-permeable layers in the Solar Cell system. In addition, emission peaks were revealed by photo luminescence spectra examination at wavelengths ranging between (542.94 nm) and (546.02 nm), which led to calculate the energy gap (Eg). of the produced films, ranged between (2.27 eV) and (2.28 eV) for the different substrates.
