Abstract

• The CdS 1-xSex (x = 0.2 mol ) sol-solution was prepared by Chemical Bath Deposition(CBD) Technique. The temperature treatment in the water bath was at 100 C for 1 h. CdSSe thin films were formed onto the pure glass substrates by chemical bath deposition method. Phase identification and crystallographic properties of CdSSe thin films were examined by X-ray diffraction (XRD) technique while the surface appearances (morphology) of fabricated films were also identified by Scanning Electron Microscope (SEM). Optical properties of CdSSe films were used by UV-Vis spectroscopy. The electrical properties of CdSSe thin film solar cells have been studied the photovoltaic (PV) performances with a focus on the influence of temperature treatment at 350 C and 400 C. The capacitance-voltage characteristics of CdSSe thin films deposited at room temperature and the effect of different thermal annealing were carried out. The maximum power output, series resistance, shunt resistance and built in voltage were calculated from the I-V and C-V measurements. This research has been focused on the investigation of structural, optical and photovoltaic performances of CdS1-xSex (x=0.2 mol) thin films by chemical bath deposition technique.
