“…It is very probable that these particles resulted from the formation of Cu x S y secondary phases on thin-film surfaces. [76,77] In Li 0.03 CTS thin film, we have observed less of these particles, which is compatible with EDX results, stating that Li 0.03 CTS thin films have a lower Cu/Sn ratio compared to undoped CTS thin films.…”

“…This defect will increase the number of grain boundaries reducing the deposition rate. [63] However, during the crystallization of Li 0.03 CTS thin films by a suitable annealing process, the incorporation of Li has improved the grain growth and enhanced the film surface, [46,76,77] which we can find from the morphological observations.…”

Cu 2 SnS 3 (CTS) semiconductor material owns very interesting absorbing properties that allow it to be effectively utilized in many thin-film-based heterojunction solar cells. In this work, using the ball milling method, a mixture of pure elemental powders is used to synthesize CTS material. Homemade undoped and Li-doped target pellets are used to form CTS-doped and CTS-undoped thin films. The crystallinity investigation of synthesized targets and thin films confirms the formation of CTS tetragonal phase. Compositional, morphologic, and optic studies are also made to examine the effect of Li atom incorporation on different properties of CTS thin films. These CTS thin films are also incorporated into heterojunction solar cells (Al/n-Si/CTS/Ag and Al/n-Si/Li 0.03 CTS/Ag). In addition, J-V characteristics of both CTS and Li 0.03 CTS solar cells are demonstrated and discussed in details. The effect of CTS thin films' thickness on the performance is studied using Solar Cell Capacitance Simulator (SCAPS-1D) program. The results of the calculation are discussed in details and compared with the experimental results. An increase in efficiency is achieved in solar cells based on Li-doped CTS thin films, and it is discussed in detail along with SCAPS-1D simulation that is carried out depending on the thickness of CTS thin films.

Cu2SnS3 (CTS) is emerging as a promising absorber for the next generation thin film solar cells (TFSC) due to its excellent optical and electronic properties, earth-abundance and eco-friendly elemental composition. In addition, CTS can be used as precursor films for the Cu2ZnSnS4 (CZTS) synthesis. The optical properties of CTS are influenced by stoichiometry, crystalline structure, secondary phases and crystallite size. Routes for obtaining CTS films with optimized properties for TFSC are still being sought. Here, the CTS thin films synthesized by magnetron sputtering on soda lime glass (SLG) using Cu and SnS2 targets in two different stacks, were studied. The SLG\Cu\SnS2 and SLG\SnS2\Cu stacks were annealed in S and Sn + S atmospheres, at various temperatures. Both stacks show a polymorphic structure, and higher annealing temperatures favor the monoclinic CTS phase formation. Morphology is influenced by the stacking order since a SnS2 top layer generates several voids on the surface due to the evaporation of SnS, while a Cu top layer provides uniform and void-free surfaces. The films in the copper-capped stack annealed under Sn + S atmosphere have the best structural, morphological, compositional and optical properties, with tunable band gaps between 1.18 and 1.37 eV. Remarkably, secondary phases are present only in a very low percent (< 3.5%) in samples annealed at higher temperatures. This new synthesis strategy opens the way for obtaining CTS thin films for solar cell applications, that can be used also as intermediary stage for CZTS synthesis.
