Chemical bath deposition (CBD) was used for the growth of thin films with low Zn content. The influence of preparation conditions, such as pH, temperature, and concentration, on film properties was investigated. The chemical growth mechanism of thin films was analyzed, and optimized growth conditions for the thin films were established. The fill factor and short-circuit current were improved while was used to replace CdS as the window layer in CdTe solar cells.

The chemical bath deposition technique was used to deposit thin films of coppersulphide onto indium tin oxide glass substrates. The bath composition included copperchloride which was the source of Cu2+ and sodium thiosulfate which supplied the S2- ions. Xraydiffraction and atomic force microscopy were used to investigate structural andmorphological characterization, respectively. The influence of deposition time was studiedto determine the optimum condition for deposition process. The deposited CuS films showedhexagonal structure. The number of peaks attributable to CuS increased as the depositiontime was increased to 16 hours based on XRD data. AFM images revealed that the chemicalbath-deposited films for 16 hours showed more homogeneous and uniform compared withother deposition times, and the highest absorbance value was obtained for the filmsdeposited at this period. The band gap energy decreased from 2.9 to 2.45 eV when thedeposition time was increased from 8 to 20 hours.Keywords: Chemical bath deposition, copper sulphide, thin films, solar cells.DOI: 10.3126/jncs.v25i0.3276Journal of Nepal Chemical Society Volume 25, 2010 pp 2-8

Chemical bath deposition (CBD) is a suitable, inexpensive, and versatile synthesis technique to fabricate different semiconductors under soft conditions. In this study, we deposited Zn(O;OH)S thin films by the CBD method to analyze the effect of the number of thin film layers on structural and optical properties of buffer layers. Thin films were characterized by X-ray diffraction (XRD) and UV-Vis transmittance measurements. Furthermore, we simulated a species distribution diagram for Zn(O;OH)S film generation during the deposition process. The optical results showed that the number of layers determined the optical transmittance of buffer layers, and that the transmittance reduced from 90% (with one layer) to 50% (with four layers) at the visible range of the electromagnetic spectrum. The structural characterization indicated that the coatings were polycrystalline (α-ZnS and β-Zn(OH)2 to four layers). Our results suggest that Zn(O;OH)S thin films could be used as buffer layers to replace CdS thin films as an optical window in thin-film solar cells.

The growth and properties of cadmium sulfide (CdS) thin films were prepared in a controlled manner using chemical bath deposition (CBD) method for different KMnO4 activation time such as 5 min, 10 min, 15 min, 20 min, 25 min, and 30 min on glass substrates. CdS thin films are deposited on KMnO4 activated glass substrates at 85°C with pH value of 10 for 30 min deposition time. In the chemical bath deposition (CBD) technique, KMnO4 activation time plays an important role in the growth of the CdS film. The structure of the CdS film changes with respect to the rate of deposition. The size of the particles is affected by the nucleation rate if the solution does not contain the constant number of Cd2+ and S2− ions throughout the deposition process. This change in structure of CdS is confirmed by the XRD, SEM, and AFM analysis, and the ion-by-ion nucleation growth is also examined. The optical property of the prepared CdS thin film is scrutinized using UV-Vis-NIR absorption analysis.
