“…Sn 3d peaks consist of a doublet with a spin-orbit splitting of 8.5 eV for Mo-CZTS [53,54] and 8.4 eV for Ti-CZTS [51,55], which is in agreement what is reported in the literature. On the other hand, Sn 3d 5/2 core level peak observed at 486 eV [56] for Mo-CZTS and 485.9 eV for Ti-CZTS corresponds to the Sn in SnS phase [57].…”

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.

“…Most of them are ''two-steps'' processes including (i) the deposition of metallic precursors either by pulsed laser deposition [5], magnetron sputtering in DC or in RF mode [6][7][8], evaporation [9,10], electro-deposition [11] or hydrazine-based liquid process [12] and (ii) the subsequent annealing in sulfurized (H 2 S or S 2 ) atmosphere in order to improve the film crystallinity and to reach the correct chemical composition. These ''two-steps'' processes allow to build solar cells with good efficiency (i.e.…”

Low-cost thin film modules based on copper antimony tin sulphide (CATS) were introduced for solar harvesting to compete for the already developed compound semiconductors. In this study, CATS thin films were deposited on soda lime glass using thermal evaporation technique followed by a rapid thermal annealing in an argon atmosphere. X-ray diffraction analysis revealed that the annealed samples were poly-crystalline and their crystallinity was improved with increasing annealing temperature. The constituent elements and their corresponding chemical states were identified using X-ray photoelectron spectroscopy. The obtained optical band gap for CATS thin film was found 1.58±0.06 eV which is nearly equal the optimal band gap value of CIGS and CdTe and GaAs -one of the highly efficient thin film material for solar cell technology. Furthermore, the good optical absorbance and low transmittance of the annealed CATS thin films in the visible region of light spectrum assured the suitability of the CATS thin films for solar cell applications.
