Abstract

Thin films of Cadmium Sulfide (CdS) are deposited on microscope glass slides by two techniques, chemical bath deposition (CBD) and close spaced sublimation (CSS). Cadmium Sulfide thin films fabricated by both procedures are characterized by spectrophotometer, scanning electron microscopy (SEM) and X-ray diffraction (XRD). Optical analysis of CdS thin films shows changes in transmittance, refractive Index and energy band gap by using two different techniques. XRD and SEM results show CdS thin film samples with better crystalline structure for close spaced sublimation technique, and grain size is also found different for these two methods. CdS thin films fabricated by any of these two methods are good window layers with small thickness and suitable for CdTe/CdS/ITO based solar cells.

Keywords

Cadmium sulfide, close spaced sublimation, chemical bath deposition morphological, optical, structural study.
