“…Figure 3b show high-resolution XPS spectrum of Cu 2p consisting two narrow and symmetric peaks at *932.80 and *952.46 eV, indicative of Cu(I) with a peak splitting of 19.66 eV. These results are well matched with the previously available data in the literature [30].The core line of Zn exhibited a doublet at *1022.17 eV and *1045.25 eV corresponding to Zn 3d 5/2 and Zn 3d 3/2 peaks with spinorbit separation 23.08 eV (Fig. 3c) suggesting presences of Zn(II) in CZTS compound [31].…”

In present work, we report synthesis of nanocrystalline Kesterite copper zinc tin sulfide (CZTS) films by RF magnetron sputtering method. Influence of calcination temperature on structural, morphology, optical, and electrical properties has been investigated. Formation of CZTS has been confirmed by XPS, whereas formation of Kesterite-CZTS films has been confirmed by XRD, TEM, and Raman spectroscopy. It has been observed that crystallinity and average grain size increase with increase in calcination temperature and CZTS crystallites have preferred orientation in (112) direction. NC-AFM analysis revealed the formation of uniform, densely packed, and highly interconnected network of grains of CZTS over the large area. Furthermore, surface roughness of CZTS films increases with increase in calcination temperature. Optical bandgap estimated using UV-Visible spectroscopy decreases from 1.91 eV for as-deposited CZTS film to 1.59 eV for the film calcinated at 400°C which is quite close to optimum value of bandgap for energy conversion in visible region. The photo response shows a significant improvement with increase in calcinations temperature. The employment these films in solar cells can improve the conversion efficiency by reducing recombination rate of photo-generated charge carriers due to larger grain size. However, further detail study is needed before its realization in the solar cells.

“…The CZTS was direct band gap semiconductor material, through the extension method it can estimate the band gap with the different sulfurization film time. As shown in figure 6, when the sulfurization were 8 min, 15 min and 30 min, the band gap of CZTS thin film was about 1.52 eV, 1.47 eV and 1.48 eV respectively, which was corresponded with the band gap reported in the literature (1.4 eV to 1.6 eV) [16] , and with the increase of sulfurization time, the band gap basically remained the same, which showed that the sulfurization time was sufficient, and the band gap of CZTS thin films had closed to the one of CZTS materials. …”

Abstract. Cu 2 ZnSnS 4 (CZTS) thin films were successfully prepared by magnetron sputtering. The composition, phase structure, surface morphology and optical properties of the CZTS thin films were characterized by X-ray diffraction, Raman spectroscopy, scanning electron microscopy (SEM) and ultraviolet visible spectrophotometer (UV-VIS). The result shows that: when the sulfurization time was 15 minutes, the atomic ratio was closed to the stoichiometric ratio of CZTS thin films, and the surface morphology of the film was homogeneous and compacted with the good uniformity. The grown films exhibit strong preferential orientation along (112) plane. As-obtained CZTS films have obvious absorptions under the visible light, and after the sufficient sulfurization, the band gap remains constant with the increase of sulfurization time.

“…The morphology of the products were investigated 19 In addition, we also found that the wurtzite CZTS has a similar Raman spectra to that of kesterite CZTS synthesized by Zou et al 27 Figure S2). Therefore, it can be confirmed that the products are pure wurtzite CZTS.…”
