Fabrication of Cu2ZnSnS4 Light Absorber Using a Cost-Effective Mechanochemical Method for Photovoltaic Applications

“…Generally, CZTS absorption coefficient in the range of the visible region is higher than 10 4 cm −1 ( Figure 7 b) [ 55 ]. As shown in Figure 7 c, the approximate values of the optical bandgap are obtained in the range of 1.50–1.57 eV [ 56 , 57 ]. The bandgap values obtained for the prepared CZTS samples are consistent with those of previous reports [ 54 , 56 , 57 ].…”

Growth of Cu2ZnSnS4 thin film absorber layer on transparent conductive oxides and molybdenum substrates by electrodeposition for photovoltaic application

“…Therefore, Raman spectroscopy was investigated and the results are presented in figure 2. Basing on the Raman spectra recorded from 260 cm -1 to 650 cm -1 ranges, the film synthesized using FTO, ITO and Mo display spectra with principal peaks recorded at 287 cm -1 , 333-338 cm -1 , and 372 cm -1 correspond to kesterite CZTS phases as reported [26][27][28][29]39].…”

Role of triethanolamine in forming Cu 2 ZnSnS 4 nanoparticles during solvothermal processing for solar cell applications

“…Cu 2 ZnSnS 4 (CZTS) semiconductors have attracted considerable attention as promising active layers for photovoltaic cells due to the earth's abundance of the raw materials as well as its low toxicity, high absorption coefficient (>10 4 cm −1 ), optimal direct energy band of 1.4 to 1.6 eV, and thermodynamically stable kesterite structure 1–4 . Many non‐vacuum deposition methods can be used to synthesize CZTS including electrodeposition, 5 spray pyrolysis, 6 spin coating, 7 and solvothermal techniques 8 . Among these non‐vacuum methods, the solvothermal approach is one of the most suitable for synthesizing CZTS‐based photovoltage devices owing to their low price and high control of the growth conditions, ability to coat large areas, low energy consumption, low pollution, and low‐temperature processing 8,9 .…”
