CdS nanostructures are important and useful materials for photovoltaic applications. In this paper, pure CdS and In doped CdS (CdS:In) thin films were fabricated on soda lime glass substrate using ultrasonic spray pyrolysis (USP) method, to investigate the effect In concentration on the structural behavior, surface and optical properties of the CdS thin films by X-ray diffraction (XRD), Atomic Force Microscopy (AFM) and Ultraviolet-visible (Uv-vis)

“…The PbS is mainly used as an infrared detector in various fields has been used mainly as an infra-red detector in another diverse field [11][12][13][14][15]. On the other hand, the CdS material shows a direct band gap between 2.42 and 2.53 eV [16][17][18][19][20][21][22][23][24][25]. The CdS material was used as a pigment as well as for solar cells optical window; cadmium sulfide is a semiconductor II-VI type which is mainly useful in optoelectronic devices and some researchers reported that it has low conductivity of 10.8 (Ω cm) −1 .…”

The goal of this chapter is to present three kind of thin films for the materials, done by Chemical Bath Deposition technique, the materials are CdS, PbS and CuS. The characterization has been diversified, but consisting mainly X-ray Diffraction (XRD) giving hexagonal, cubic and amorphous structures of CdS, PbS and CuS respectively. The Raman dispersion let to found the characteristics peaks of vibration, one for the CdS located on 300.7 cm −1 , three for PbS and two more for the CuS. We use X-rays Photoelectron Spectroscopy to formalize the chemical composition analysis, from this analysis we could to proof the high purity of the chemical bath deposition method in the materials preparation. We used UV-Vis Spectroscopy to determine simple optical responses, getting the biggest transmittances of 72% for CdS, 45% for PbS, and 80% for CuS, and direct energy band gaps of 2.47 eV for CdS, 1.78 eV for CuS as ground and with thermic annealing 2.45 eV which is believed result of amorphous to crystalline morphology changes, the indirect bandgap 0.94 eV is measured too. The AFM given information about the surface morphology and roughness, Scanning Electron Microscopy (SEM) micrography shows the polycrystallinity nature of the CuS including the smooth.
