“…In addition, SnS semiconductor can have p‐type or n‐type electrical conductivities (Messaoudi et al, 2019). SnS thin films can be prepared by several methods such as chemical bath deposition (CBD) (Khan et al, 2022), vacuum evaporation method (Sharma et al, 2020), electrodeposition (Cheng et al, 2006; Jamali‐Sheini et al, 2017), dip coating (Chaki et al, 2016), spin‐coating process (Garmima et al, 2022), and spray pyrolysis. Among these techniques, spray pyrolysis is a simple and less expensive method compared to other chemical methods; it does not require any vacuum vessels and is suitable for large surface substrate coating (Messaoudi et al, 2020; Nouri et al, 2022).…”

In the present experimental work, Tin Sulphide (SnS) thin films with various thicknesses have been grown on nonconducting substrate by using chemical spray pyrolysis technique in order to study the extent of dependence of crystallite size, morphological and optical properties of SnS films on their deposition times. The obtained films were characterized using x‐ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), UV–visible and Hall Effect measurements. From 15 min to 60 min with an increase of 15 min each time one of all films was deposited, the XRD analysis indicated that all four sprayed SnS films are mainly composed with orthorhombic SnS phase, having a growing dominant peak intensity (120), with increasing deposition time. In addition, the XRD revealed the presence of the Sn2S3 secondary phase in SnS film sprayed at the longest time (60 min). It was found that the measurements of crystallite size and microstrain are varied in the inverse manner throughout the deposition period. The SEM and AFM analysis revealed that the morphology of sprayed films have good surface coverage without pinholes or cracks. AFM analysis confirmed that the root‐mean‐square (RMS) roughness behavior of the sprayed films increases from 14.6 to 56.7 nm with increasing deposition time. Optical studies showed that the transmittance decreases with the deposition time increase, and the minimum value of Urbach energy was 360 meV for the film deposited at 45 min, showing an improvement of the SnS film crystallinity. In addition, the optical band gap values significantly increased from 0.69 to 2.10 eV by increasing the deposition time from 15 min to 60 min. The Hall Effect study showed that SnS thin films have p‐type conductivity. The lowest resistivity and higher carrier concentration were found to be 0.134 Ω cm and 8.15 × 1019 (ion/cm−3), respectively. These obtained results revealed that the deposition time interestingly affect the properties of sprayed SnS films, which would qualifying them to meet the requirements to be serve in different applications.

“…5 Several works have investigated the preparation of SnS chalcogenide absorber thin films using a variety of methods such as electrodeposition, 6 spray pyrolysis, 7 Chemical Bath Deposition, 8 Ionic Layer Adsorption and Reaction (SLAR), 8 close-spaced vacuum sublimation technique, 9 RF method, 10 sol gel spin coating. 11 sol-gel associated with spin coating is a simple, fast, and inexpensive chemical technique that delivers reliable results. Another advantage of this technique is the production of thin films with good uniformity and controllable thickness on all types of substrates.…”

“…Several previous study have successfully synthesis SnS thin films by sol-gel spin coating method. [11][12][13][14][15] In Addition, One of the steps in the preparation of SnS thin films by the sol gel spin coating method is the preparation of a pre-cured solution. For this reason, it is essential to choose a solvent that allows the starting solution to be of high quality, which helps to produce SnS absorber thin films with attractive properties for use in solar cells based on the thin films as an absorber layer.…”

In the current study, the sol-gel spin coating was used to deposit SnS thin films on ordinary glass substrates, and annealed without sulfurization at 500°C. Different organic solvents such as ethanol, 2-methoxyethanol, and methanol were used and their influence on the properties of SnS thin films was investigated. X-ray diffraction showed that the three prepared films have an orthorhombic structure with preferred orientation along (111) plan. In addition, the obtained films from ethanol solvent present better crystallinity with larger grain sizes around to 28.19 nm. Morphological and compositional analysis was obtained with a scanning electron microscope associated with an X-ray spectrometer. The results show better texture with uniform coverage on the glass substrate of the deposited films obtained for ethanol as solvent. The optical analysis obtained from the UV-vis spectrophotometer reveals that the deposited films show a broad absorption spectrum in the visible region and the band gap was found to lie in the range of 1.51 to 1.95 eV. The four-points probe measurement revealed smaller electrical resistivity for the films obtained from ethanol 1.76 x102(Ω.cm) and a higher conductivity 5.68 x10-3(Ω.cm)-1.
