“…CdS films with the grain size in the range of 200-300 nm (Figure 4) in the case of the pH value of the solution being about 3 and the temperature being 85 °C. Altiokka et al deposited CdS films when the pH value of the electrolyte varies [38]. They confirmed that the pH value of the electrolyte has an important impact on the morphology of the deposited film.…”

Electrodeposition, which features low cost, easy scale-up, good control in the composition and great flexible substrate compatibility, is a favorable technique for producing thin films. This paper reviews the use of the electrodeposition technique for the fabrication of several representative chalcogenides that have been widely used in photovoltaic devices. The review focuses on narrating the mechanisms for the formation of films and the key factors that affect the morphology, composition, crystal structure and electric and photovoltaic properties of the films. The review ends with a remark section addressing some of the key issues in the electrodeposition method towards creating high quality chalcogenide films.

“…When the thin films were produced as two and three layers, the crystallite sizes decreased about 5 times. Quantization effects are observed when the crystallite size of a semiconductor is near to or less than the bulk Bohr exciton radius [29,30]. Generally, when the crystallite size of PbS quantum dots decreases to 5-18 nm, it is seen [31].…”

In this study, the (Lead Sulfide) PbS thin films with one, two, and three layers were fabricated by employing the chemical bath deposition method. Layer by layer production of PbS thin films was realized for the first time as seen in the literature review. For investigating the crystal structures, the X-ray diffraction (XRD) analysis was used. The structural analyses indicated that the crystallite size was decreased from about 40 nm to 8-10 nm depending on the number of layers. The surface micrographs of the films were obtained using scanning electron microscopy (SEM). When the PbS film was obtained in one layer, some cracks, pinholes, and voids were observed on the sample surface. However, no cracks, voids, or pinhole formation were found on the film surface when the films were coated in two and three layers.

“…Cadmium sulfide (CdS) is an II-VI semiconductor compound widely used as a window layer in thin-film solar cells based on cadmium telluride (CdTe), copper indium gallium sulfide and diselenide (CIGS or CIGSe), and copper zinc tin sulfide (CZTS) absorbers [1][2][3]. This is due to its excellent optical and electrical properties, such as a direct band gap energy of 2.42 eV [4,5], an absorption coefficient of 4x10 4 cm -1 [6], therefore only 100 nm thickness is required to absorb about 63% of the incident radiation [5].…”

Indium doped CdS thin films, with different In/CdS ratios, were fabricated employing chemical bath deposition technique. The incorporation of indium was carried out in the first stages of the process. The effects of In-doping on structural, surface, optical and electrical properties were determined using X-Ray Diffraction (DRX), Scanning Electron Microscope (SEM), UV-VIS Spectroscopy and Hall Measurements respectively. XRD studies showed cubic structures for all samples and that In3+ ions where incorporated into the lattice substitutionally at low concentration, and interstitially at high concentration. SEM measurements revealed that films morphology was unaffected by indium doping. The transmittance of In doped films was above 70% for all samples and the calculated band gap was between 2.32 and 2.44 eV. The electrical properties show an increment in carrier concentration from 1.3 x 1015 cm-3 to 2 x 1016 cm-3 and decrease in the resistivity from 2.13 x 1016 Ω to 1.5 x 1015 Ω due to indium doping.
