Paper Title
Chemical-Bath Deposition for Different Thickness CDS Buffer Layer on Cigs Solar Cell

Abstract
Chemical bath deposition (CBD) method is used to deposit n-type Cadmium sulfide (CdS) thin film on Cu(In, Ga) solar cell. Different CdS thin film thicknesses were obtained via changing different deposition time (20, 30, 40 min).The thicknesses were determined of 89, 167, 247 nm by SEM. This paper mainly discussed the structural, optical properties and efficiency parameters of three different thicknesses of CdS thin films deposited on CIGS absorber layer using X-ray diffraction spectroscopy (XRD), scanning electrode microscope (SEM) and UV-Vis spectrophotometer. The result reveals that the thicknesses effect the transmittance at longer wavelength region more. The 89 nm CdS thin film device has the most high efficiency of 8.04%, 0.45V, 6.81 mA, FF 0.52. From the result, the proper thickness of CdS thin film is estimated of 50-100 nm. Keywords: CBD, CdS, Buffer layer, CIGS, solar cells
