“…The deposition procedure for SnS and SnS 2 films by CSP is schematically presented in Figure 2, and the process has been described in detail in our previous reports [35,36]. Analytical-grade tin chloride (SnCl 2 .2H 2 O, 0.1 M) and tartaric acid (C 4 H 6 O 6 , 1.2 M) were used as a tin source and complexing agent, respectively, and 10 mL of thioacetamide (C 2 H 5 NS, 0.50-0.75 M) was used as the source material for the S ions.…”

Eco-friendly tin sulfide (SnS) thin films were deposited by chemical solution process using varying concentrations of a sulfur precursor (thioacetamide, 0.50–0.75 M). Optimized thioacetamide concentrations of 0.6 and 0.7 M were obtained for the preparation of single-phase SnS and SnS2 films for photovoltaic absorbers and buffers, respectively. The as-deposited SnS and SnS2 thin films were uniform and pinhole-free without any major cracks and satisfactorily adhered to the substrate; they appeared in dark-brown and orange colors, respectively. Thin-film studies (compositional, structural, optical, and electrical) revealed that the as-prepared SnS and SnS2 films were polycrystalline in nature; exhibited orthorhombic and hexagonal crystal structures with (111) and (001) peaks as the preferred orientation; had optimal band gaps of 1.28 and 2.92 eV; and exhibited p- and n-type electrical conductivity, respectively. This study presents a step towards the growth of SnS and SnS2 binary compounds for a clean and economical power source.

“…Generally, the films prepared at lower T b have smaller grains, and those grains increase in size with T b due to the covering of voids by secondary nucleation ( Figure 8 b) [ 50 , 212 ]. The change in grain shape may indicate a change in the growth mechanism [ 146 ].…”

“…The c-SnS films show a non-stoichiometric composition at higher and lower Tb values due to the relatively faster and slower release of Sn 2+ ions from the tin complex due to the variation of thermal energy in the solution [ 50 ]. Single-phase, polycrystalline o-SnS films with (111) preferred orientation and c-SnS films with (222)/(400) preferred orientation are produced separately at T b of 70 °C [ 212 ] and 65 °C [ 50 ] using a different source of materials ( Table 4 ), respectively.…”

“…The T b can directly affect the crystallinity of both o-SnS and c-SnS films. The crystallinity of both films is improved with T b due to the supply of sufficient thermal energy for further crystallization ( Figure 8 c) [ 50 , 212 ]. Thus, an average crystallite size is improved with T b —however, up to a certain extent [ 212 ].…”

The rapid research progress in tin-based binary sulfides (SnxSy = o-SnS, c-SnS, SnS2, and Sn2S3) by the solution process has opened a new path not only for photovoltaics to generate clean energy at ultra-low costs but also for photocatalytic and thermoelectric applications. Fascinated by their prosperous developments, a fundamental understanding of the SnxSy thin film growth with respect to the deposition parameters is necessary to enhance the film quality and device performance. Therefore, the present review article initially delivers all-inclusive information such as structural characteristics, optical characteristics, and electrical characteristics of SnxSy. Next, an overview of the chemical bath deposition of SnxSy thin films and the influence of each deposition parameter on the growth and physical properties of SnxSy are interestingly outlined.
