“…Moreover, all films showed a privileged orientation along (111), which are in good agreement with those reported in the literature. [29,30] However, their relative intensities are dependent on zinc concentration as shown in Figure 1. The intensity of the peaks decreases as the zinc concentration increases from 0.1 to 0.3 m probably due to the decrease in the crystalline quality of the films.…”

“…It can be noticed that increasing the molar concentration of Zn created a more porous and spindle-shaped surface with a high density of nucleation and interconnection between shapes, and this is similar to the results found in literature. [30,52] The film thickness containing a Zn molar concentration of 0.1 was obtained using cross-section by SEM techniques as shown in Figure 7. The obtained film thickness is near to ≈1μm.…”

This study aims at synthesizing zinc sulfide (ZnS) thin films using spray pyrolysis method. The effect of the Zn concentration on the physical properties of ZnS is investigated using X-ray diffraction (XRD), scanning electron microscope (SEM), UV-Vis spectrophotometer, photoluminescence (PL), and Raman spectroscopy. XRD shows a preferential orientation along the (111) direction corresponding to the ZnS cubic structure. Based on the XRD results, it is seen that low zinc concentrations compared to sulfur content can increase the crystalline quality of films. Raman spectra confirm the presence of the ZnS cubic structure observed by XRD and show the presence of sprayed ZnS vibrational modes for all films. PL emission spectrum of ZnS confirms the presence of Zn and S atoms at all molar concentrations. SEM reveals densely packed and uniformly distributed grains with precise shapes. The elemental analysis confirms the growth of stochiometric Zn/S ratio. The optical analysis shows a high transmittance around 88% in the visible range of the solar spectrum with optical band gaps varying from 3.4 to 3.6 eV. These properties are interesting and show that ZnS thin films can be used as buffer layers in thin film solar cells applications.
