“…CdS thin films can be synthesized using several deposition techniques through various physical and chemical methods such as molecular beam epitaxy (MBE) [15], sputtering [16], thermal evaporation [17], spray pyrolysis [18], chemical bath deposition [19], successive ionic layer adsorption and reaction [20], and electrodeposition [21]. Among these techniques, chemical bath deposition (CBD) is a simple and cheap method that can produce uniform and adherent large-area films [22].…”

In this work, thin CdS films have been deposited using the chemical bath deposition technique (CBD). Different synthesis parameters, such as number of runs, deposition time, and postannealing temperature, are studied and optimized in order to avoid the supersaturation phenomenon and to achieve a low-temperature growth. CdS thin films, of cubic structure, oriented along the (111) direction with homogenous and smooth surface, have been deposited by using the CBD growth process without any annealing treatment. Based on a set of experimental observations, we show that the solution saturation phenomenon can be avoided if the deposition is performed in several runs at a short deposition time. Throughout the CBD technique, it is then possible not only to overcome any film thickness limitation but also to grow the CdS films in a single technological step at a low temperature and without any postdeposition annealing treatment. CdS films with excellent structural quality and a controllable thickness are obtained when the deposition bath temperature is fixed at 65°C. In addition, deposited films exhibit an optical transmittance ranging from 70 to 95% depending on the synthesis parameters, with band gap energy around 2.42 eV. The process developed in this work might be useful for depositing CdS films on flexible substrates.

Polycrystalline CdS thin films comprising of hexagonal crystal structure are successfully fabricated by pulse electrodeposition using a two-electrode system at room temperature. The method utilizes tartaric acid as a complexing agent for the first time that minimizes the formation of colloidal sulfur while optimizing the deposition potential and avoids conventional post-deposition heat-treatment step. Additionally, deposition time is varied to obtain the desired thickness of CdS films suitable for application in thin films solar cells. Pulse electrodeposited CdS films are comprehensively characterized using SEM, XRD and micro-Raman analyses unveiling the stoichiometric polycrystalline hexagonal CdS films. The bandgap is determined to be around 2.4 eV from optical studies. Flat-band potential and carrier density are inferred to be −0.82 V vs SCE and 8.51 × 10 18 cm −3 , respectively, from the Mott-Schottky analysis. Photoelectrochemical studies show a photocurrent density of about 0.2 mA/cm 2 at 0.2 V vs SCE for the optimized films, which is competent with previously reported values. These pulse electrodeposited CdS films prepared without any high-temperature treatment are of high quality with desirable properties and are suitable for application in thin films solar cells and photoelectrochemical cells.

Cadmium Sulphide thin films have been successfully electrodeposited on a conducting Indium-Tin-Oxide (ITO) glass substrate, with different deposition time (10 min, 20 min, and 30 min). The Scanning electron microscopy (SEM), UV-Vis spectrophotometry, X-ray diffraction (XRD), and Atomic force microscopy (AFM) were used to characterize the morphological of films obtained. Moreover, Mott–Schottky (MS) measurements and Photoelectrochemical (PEC) measurements were carried out to study their structural, optical and electrical properties respectively. XRD result points to high crystallinity oriented along (002) planes. The studies reveal that the optical transmission increases with decreasing time of deposition. Mott-Schottky and Photoelectrochemical studies indicates that the CdS thin films display n-type semiconductor, which allows used as layer in photovoltaic cell applications.
