“…According to previous SEM results, higher sulfurizing temperature would lead to phase purification and crystallinity improvement, which may probably contributed to the band gap reduction. In all, the band gap value in the range of 1.4-1.5 eV [25,30,33] matches well with solar spectrum and thus quite suitable for developing CZTS-based single junction solar cells.…”

Solar cells and related key materials are still among the most interesting researching field. In this work, kesterite Cu 2 ZnSnS 4 (CZTS) cross-linked fibers and dense films, which are promising candidates for active layers used in the third generation solar cells, are developed via electrospinning following sulfurization at high temperature. Morphology dependence and properties evolution are investigated for the samples obtained by sulfurization in the temperature range of 450-600°C. Samples are characterized by scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction, Raman and X-ray photoelectronic spectroscopy, and UV-Vis absorbance spectra. It is found that, with the sulfurization temperature increasing, morphologies develop from isolated CZTS fibers to interconnected fibers, and finally forming a submicron flake composed dense films, accompanying a band gap evolution from 1.49 to 1.44 eV, just by simply adjusting the solutes concentration and vulcanization parameters.

“…Several methods have been used in the fabrication of CZTS thin film absorber layers, such as atomic beam sputtering [5], e-beam evaporation [6], thermal evaporation [7], magnetron sputtering [8][9][10][11], electrodeposition [12,13], spray pyrolysis deposition [14,15], pulsed laser deposition [16], etc. Most of these techniques were carried out using rigid substrates such as bilayer molybdenum (Mo) coated soda lime glass (SLG).…”

In this work, Cu 2 ZnSnS 4 (CZTS) absorber layers were fabricated using a two-stage process. Sequentially deposited Cu-Zn-Sn thin film layers on metallic foils were annealed in an Ar + S 2(g) atmosphere. We aimed to investigate the role of flexible titanium and molybdenum foil substrates in the growth mechanism of CZTS thin films. The Raman spectra and X-ray photoelectron spectroscopy analyses of the sulfurized thin films revealed that, except for the presence of Sn-based secondary phases, nearly pure CZTS thin films were obtained. Additionally, the intense and sharp X-ray diffraction peak from the (112) plane provided evidence of good crystallinity. Electron dispersive spectroscopy analysis indicated sufficient sulfur content but poor Zn atomic weight percentage in the films. Absorption and band-gap energy analyses were carried out to confirm the suitability of CZTS thin films as the absorber layer in solar cell applications. Hall effect measurements showed the p-type semiconductor behavior of the CZTS samples. Moreover, the back contact behavior of these metallic flexible substrates was investigated and compared. We detected formation of cracks in the CZTS layer on the molybdenum foils, which indicates the incompatibility of molybdenum's thermal expansion coefficient with the CZTS structure. We demonstrated the application of the magnetron sputtering technique for the fabrication of CZTS thin films on titanium foils having lightweight, flexible properties and suitable for roll-to-roll manufacturing for high throughput fabrication. Titanium foils are also cost competitive compared to molybdenum foils.

“…Up till now, numerous CZTS thin film preparation methods are reported, such as electrode position [4], pulse laser deposition [5], thermal deposition [6], spray pyrolysis [7], sol-gel spin coating [8], etc. Among these techniques, the sol-gel spin coating is most preferred for low-cost thin film preparation [9].…”
