We have prepared<br>CZTS thin films by sol-gel dip-coating process from chloride-based chemicals. After vacuum-annealed at 550°C, the optical and<br>structural characters of the films were further examined by UV–vis spectroscopy, X-ray diffraction (XRD), scanning electron<br>microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS) methods. The CZTS films offered high optical absorption<br>(0.4x104cm-1) and nearly optimum bandgap energy (1.65e V). X-ray diffraction examination confirmed the kesterite structure of<br>films. Scanning electron micrograph affirmed the creation of jam-packed, condensed and granulated CZTS films. The thin film<br>displayed intermittent disposal of agglomerated particles with clear-cut edges. The energy dispersive X-ray spectroscopy study gave<br>the stoichiometric ratio as Cu: Zn: Sn: S= 2.2: 1.4: 1: 5.1.</p> <p>Dhaka Univ. J.
