“…Based on the previous reports, it has been determined that annealing at higher temperature is necessary for the re-crystallization process, which may due to improvement in crystallinity [31]. Average crystallite size calculated using Scherrer formula [32] and micro strain calculated using equation [33] of AT300 sample, are around 26 nm and 8.85 10 .…”

Tin sulfide (SnS) has attracted significant interest due to its advantageous optoelectrical characteristics and abundant presence in nature. Post-deposition treatments (PDTs) are frequently employed to enhance the crystallinity of chalcogenide-based solar cells. This study examined the influence of the post-deposition heat treatment procedure on thermally evaporated SnS thin film. The post-deposition annealing process, as determined by XRD and AFM studies, supplies the necessary thermal energy for re-crystallization, potentially resulting in a modification of crystallite dimensions. The occurrence of Sn-S polytypes was examined using Raman and XPS studies. Annealing causes changes in the optical properties, as observed through optical analysis, which can be attributed to the improvement in crystallinity. Subjecting the material to annealing at temperature of 300 °C greatly improves both mobility and conductivity, while also causing a change in conduction type. The observed variations in conduction type are attributed to the differing ratios between the amounts of Sn2+ and Sn4+. This strategy offers a novel route for the fabrication of thin-film photovoltaic cells by using a p-type buffer layer.

In this study, Mg-doped zinc oxide (MZO) thin films were deposited through radio frequency (RF) sputtering for different substrate temperatures ranging from room temperature (25 °C) to 350 °C. XRD analysis depicted that the higher substrate temperatures lead to increased crystallite size. From the UV–Vis spectroscopy, transmittance (T) was found approximately 95% and the optical band energy gap (Eg) was determined around 3.70 eV. Hall effect measurement system measured the carrier concentration and resistivity of all films in the order of 1014 cm−3 and 103 Ω-cm, respectively. Since the structural and optoelectrical properties of the MZO films were not significantly affected by the substrate temperatures, Aluminium (Al) was co-doped in the MZO film to improve structural and optoelectrical properties. As a result, the carrier concentration of Al doped MZO (AMZO) films was increased up to ~ 1020 cm−3 from ~ 1014 cm3 (MZO), and the resistivity was decreased up to ~ 10–1 Ω-cm from 103 Ω-cm (MZO) representing the significant changes in electrical properties without affecting the transmittance. This study opens a pathway for improving the MZO buffer layer that can enhance the cell performance of CdTe solar cells. Graphical abstract
