“…All films have homogeneous, smooth and consistent surface with spherical crystallites. This observed symmetry might be attributable to enormous surface energy of these crystallites and appear great attachment to the film surface because of the effect of TX-100 surfactant, which has been already reported [43,44]. Cauliflowers like globules appeared in the thicker CdS film surface, which matched well with the previous report [45].…”

Cadmium sulfide (CdS) is considered as a superior buffer/window layer in thin-film solar cells apart from its various applications. The thickness of the buffer/window layer that defines the interface between the absorber layer is very important and needs to be thoroughly investigated for optimized device performance, particularly when a novel synthesis route and deposition technique is used. This manuscript presents the investigation on the various structural, morphological, and optical parameters and their correlation with the thickness of CdS thin film synthesized using a novel thiol-amine cosolvent with the help of Triton-X 100 surfactant. Spin coating technique is used to deposit CdS thin-films having thicknesses ranging from 100 to 300 nm on a glass substrate. X-ray diffraction (XRD) exposed the polycrystalline nature of the CdS films. All the diffraction peak intensities were found to increase with the thickness. Structural parameters like dislocation density, lattice strain, and crystallites per unit area calculated from the XRD data were found superior to those parameters for CdS films synthesized through various chemical routes, and the parameters indicated a positive correlation of the degree of crystallinity on the thickness. Similarly,surface morphology and optical properties of CdS films that were investigated by the scanning electron microscope (SEM) and UV-VIS spectrophotometer, were also dependent on film thickness. These results show that CdS thin film with superior crystallinity can be synthesized using thiol-amine cosolvent along with the Triton-X 100 surfactant and deposited by low-cost spin-coating on glass substrate. Moreover, the thickness variation appeared to be a single tool for obtaining application-specific various properties of CdS thin-film.

Kadmiyum sülfür filmleri kimyasal banyo depolama yöntemi ile cam tabanlar üzerine biriktirildi. Elde edilen filmler azot gazında 1 saat boyunca 200-400 o C sıcaklık aralığında tavlandı. Filmlerin kristal yapısı x-ışını kırınım (XRD) desenlerinden belirlendi. XRD verileri, tavlama etkisiyle CdS (FCC) yapısından α-CdS (Hawleyite) formuna geçiş olduğunu gösterdi. Elde edilen CdS filmlerinin optiksel bant aralığı değerleri optiksel absorbans spetrumlarından yararlanılarak 2,33 ve 2,39 eV olarak belirlendi. Bant sarkmaları değerleri 120-350 meV arasında olduğu hesaplandı. Filmlerin görünür bölgede %45-92 arasında geçirgenlik değerlerine sahip olduğu belirlendi.

Undoped and molybdenum doped CdS thin films were deposited on glass substrates using Improved Successive Ionic Layer Adsorption and Reaction (ISILAR) technique. The Mo doping level was varied from 0 to 15 at.% in steps of 5 at.%. The XRD analysis shows that all the films are polycrystalline with cubic structure and grow preferentially along the (111) plane. The crystallite size increases gradually with the increase in Mo doping level up to 10 at.% and decreases with further doping. The morphological studies reveal that Mo doping significantly affects the grains size. Qualitative and quantitative compositional analysis show that near stoichiometric undoped and Mo doped CdS thin films can be achieved using this ISILAR technique. All the films exhibit high transparency in the visible region with an average transmittance in the range of 85–95%.
