CZTS precursors were prepared using a sol-gel method and deposited by spin-coating; they were subsequently preheated at 150 �C under different atmospheres (air, Ar, and N2) prior to sulfurization at 580 �C. X-ray diffraction (XRD) patterns confirmed the formation of crystalline CZTS with different crystallite sizes, while the Raman spectroscopy results showed that the synthesized films are composed of the stannite CZTS phase. CZTS films preheated in Ar and N2 show better crystallinity, larger grains, and improved surface morphology with less oxygen content compared with as-deposited and air-preheated samples. A suitable bandgap is obtained in all samples, with better absorption in Ar and N2. Notably, lesser surface microstructural inhomogeneity is observed in samples preheated in Ar and N2 atmospheres, which indicates that both of those environments are suitable for the deposition of CZTS materials for application in solar cells. � 2020 Elsevier Ltd Final 2023-05-29T08:10:31Z 2023-05-29T08:10:31Z 2020 Article 10.1016/j.spmi.2020.106452 2-s2.0-85080084704 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85080084704&doi=10.1016%2fj.spmi.2020.106452&partnerID=40&md5=15841c1951ebc5c733f5fe7822635057 https://irepository.uniten.edu.my/handle/123456789/25531 140 106452 Academic Press Scopus
