“…It is because crystalline quality of the film plays an important role in the utilization of the CdS films for solar cell applications and thermal annealing leads to improve the crystalline quality of the films by the removal of strains, which can lead to the phase transition and thereby changing the band gap. Since annealing brings positive as well as negative effects to CdS physical properties [7,8], therefore, a better understanding of the impact of the annealed CdS film on the properties of the CdS/CdTe solar cell is still needed. Polycrystalline CdS thin films have been prepared by different techniques including vacuum evaporation [9], chemical bath deposition (CBD) [10], electrodeposition [11], sputtering [12], and laser ablation [13].…”

Cadmium sulfide (CdS) thin films are deposited on the fluorine doped tin oxide coated glass substrate using the radio frequency magnetron sputtering setup. The effects of annealing in air on the structural, morphological, and optical properties of CdS thin film are studied. Optimal annealing temperature is investigated by annealing the CdS thin film at different annealing temperatures of 300, 400, and 500°C. Thin films of CdS are characterized by X-ray diffractometer analysis, field emission scanning electron microscopy, atomic force microscopy, UV-Vis-NIR spectrophotometer and four point probe. The as-grown CdS films are found to be polycrystalline in nature with a mixture of cubic and hexagonal phases. By increasing the annealing temperature to 500°C, CdS film showed cubic phase, indicating the phase transition of CdS. It is found from physical characterizations that the heat treatment in air increased the mean grain size, the transmission, and the surface roughness of the CdS thin film, which are desired to the application in solar cells as a window layer material.

“…4, the relationship between E g and absorption edge slope is therefore an inverse type. As explained by Han et al [37], semiconductor materials with sharper absorption edge will have lesser impurity energy levels and defects in the thin film. The explanation given by Han et al [37] demonstrates the possibility of GC+CC-treated CdTe layers to have lesser defects.…”

“…As explained by Han et al [37], semiconductor materials with sharper absorption edge will have lesser impurity energy levels and defects in the thin film. The explanation given by Han et al [37] demonstrates the possibility of GC+CC-treated CdTe layers to have lesser defects. Another advantage of having a sharp absorption edge is that it allows more photons to be absorbed even when the CdTe thickness is of few microns [30].…”

Nanocrystalline thin films of cadmium sulphide were prepared by chemical bath deposition technique onto glass substrate at 60 °C. The deposition parameters were optimized to obtain good quality of nanocrystalline thin films such as, time, precursor concentration, temperature of deposition and pH of the solution. The studies on crystal structure, composition, surface morphology, electrical conductivity and photoconductivity of the films were carried out by using different analytical technique. Characterization includes X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), Energy dispersive X-ray analysis (EDAX), Electrical and photoconductivity. The response and recovery time of the thin film were measured and presented.
