Nanocrystalline cadmium sulfide thin films are prepared using chemical bath deposition (CBD) technique in aqueous alkaline bath at 60 °C and their subsequent condensation on glass substrates. Effects of annealing on structural, morphological and optical properties are presented and discussed. The best annealing temperature for CBD grown CdS films is found to be 350 °C from optical properties. The optical and structural properties of CdS films are found to be sensitive to annealing temperature and are described in terms of XRD, SEM, transmission spectra and optical studies. The structural parameters such as crystallite size have been evaluated through XRD while SEM micrographs exhibit ordering of grains upon annealing. The transmission spectra shift towards higher wavelength upon annealing indicating increase in crystallinity. Annealing over 350 °C is found to degrade the external structure and optical properties of the film.

In this work, cadmium sulphide (CdS) buffer layer of CuInSe2 (CIS) thin film solar cell is fabricated by separate-melting Chemical Bath Deposition (CBD) methods. The reason of adopting the CdS thin film as the buffer layer of CIS thin film solar cell is that the CdS can act as energy gap buffer and reduce the band-offset between CIS absorbing layer and the Transparent Conductive Oxide layer. The CdS thin films are generated by the separate-melting CBD methods in situation of atmosphere. In order to analyze the characteristics of the CdS thin films conveniently, the CdS thin films are firstly fabricated on Soda-lime, and the final found optimal CdS thin film is fabricated on the CIS/Mo/Soda-lime glasses. Then the p-n diode characteristic of the CdS/CIS/Mo/Soda-lime glasses is measured by four-point probe. And the CdS thin films are fabricated by the separate-melting CBD methods through various combinations of time interval from 40 and 60 minutes and temperature range from 70,75,80 and 85°C. It is found that the combination of 85°C and 60 minutes is optimal to obtain smoother surface and more uniform thickness of CdS thin film. Additionally from optical characteristic analysis, in situation of emitted light wave length 500 nm, the transmittance of the cadmium sulphide thin film is 61%. Meanwhile, the band gap is close to theoretical value of 2.4 eV.

Cd1-xZnxS thin films were deposited on glass substrates by chemical bath deposition (CBD). The effect of ZnSO4 solution concentration on the properties of the thin films was analyzed. The concentration of ZnSO4 solution affects the deposition rate of Cd1-xZnxS thin films. When the deposition rate is low, Cd1-xZnxS cubic crystal phase is formed. The surface morphology of hexagonal Cd1-xZnxS thin films is denser than that of cubic phase, the lattice mismatch rate of cubic phase Cd1-xZnxS thin films and CIGS is lower, only 0.56%, the interfacial state density is lower. SCAPS software was used to simulate the performance of the buffer layer, and the conversion efficiency of the cubic phase Cd1-xZnxS buffer layer in CIGS Solar Cell was up to 23.50%. Based on the EDS results, the function relationship between the contents of Zn2+ and Cd2+ in the films and the band gap content was deduced.
