The focal aim of our investigation is on the impact of metallic precursors� Cu/Sn ratio on the overall material properties of CTS films, which in turn, influence the photovoltaic device performance. All CTSs exhibited polycrystalline films with a mixture monoclinic CTS and orthorhombic SnS compound, p-type conductivity, and optical band gap in the range of 0.84�0.90 eV. Metallic precursor with Cu/Sn ratio of 1.09 produced optimum CTS film with post-sulphurization Cu/Sn ratio of 1.98 and highest conversion efficiency of 0.71%, respectively, despite exhibiting pronounced formation of SnS secondary phase. The correlation between XRD, Raman, and SEM-EDX outcomes revealed that CTS films from metallic precursors with Cu/Sn ratio higher than 1.09 undergo severe microstructural degradation due to Sn-loss through decomposition of volatile SnS phase and consequently, resulted in poorer absorber layer quality and lower device performance. Finally, several efficiency impeding factors are discussed and practical propostions to overcome them are presented. � 2018 Elsevier Ltd Final 2023-05-29T07:30:58Z 2023-05-29T07:30:58Z 2019 Article 10.1016/j.solener.2018.10.081 2-s2.0-85056565604 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85056565604&doi=10.1016%2fj.solener.2018.10.081&partnerID=40&md5=8bb77954b6d63ba494a0990d0da6cc55 https://irepository.uniten.edu.my/handle/123456789/25046 177 262 273 Elsevier Ltd Scopus |
