“…Where Hassanien et al, [22] reported the increase in crystallite size value from 4.5nm to 38.8nm for CZTS with an annealing temperature of 400 °C to 550 °C, Liping Chen et al, [23] observed the increase in crystallite size from 5.60nm to 19.97nm in CZTS when annealed from 250 °C to 550 °C, Giedrė Grincienė et al, [24] reported the size of crystallites increases from 2.4 to 24.1 nm for CZTS with the increase of annealing temperature from 300 °C to 550 °C. The decrease in microstrain and dislocation density with an increase in crystallite size implies a less number of lattice defects i.e.…”

Fabrication of economically viable photocathode for hydrogen energy production through solar water splitting is a major research among the scientific community for a decade. P-type compound Cu2ZnSnS4 (CZTS) is very interesting material due to its absorption property, earth-abundant constituents and environmental friendliness that serves as a suitable candidate to act as a photocathode. In the present work, Cu2ZnSnS4 (CZTS) nanoparticles are synthesized by simple one-step chemical method and annealed at 350 °C for three different times (60 minutes, 90 minutes and 120 minutes). The effect of annealing time on the structural, optical and photoelectrochemical properties are investigated. XRD pattern indicates the formation of tetragonal crystal structure and the crystallinity increases according to the annealing time. 2-D nanoplate morphology is obtained for the sample that was annealed for 120 minutes. From the absorption spectra, it was found that the band gap decreases with increase of annealing time. Further, the prepared nanoparticle thin films are used as a cathode for photoelectrochemical water splitting application. Among these, the nanoparticles that are annealed for 120 minutes showed higher photocurrent density when compared to nanoparticles annealed for 60 minutes and 90 minutes.

“…The band gap energies were obtained by plotting (αhυ) 2 as a function of hυ [47]. The band gap energy for CZTSe and CZTS are 1.0 eV and 1.5 eV, respectively [48][49][50]. The extrapolated absorption edges of the CZTSSe samples deposited from the DMF, DMSO, and H 2 O-EtOH solutions and annealed at a temperature of 540 °C correspond to 1.21, 1.29 and 1.31 eV band gap values, respectively.…”

The Cu 2 ZnSnS 4 (CZTS) thin films were deposited by means of spray pyrolysis technique on the Mo/glass substrate, which was heated in the air at a temperature of 320 °C. Samples were prepared using solutions with different solvents: dimethylsulfoxide (DMSO), dimethylformamide (DMF) and water-alcohol (H 2 O-EtOH). Further, the CZTS films were selenized at a temperature of 540 °C. The influence of the solvents on the crystalline structure, phase composition and optical properties of the CZTS and CZTSSe films were investigated using XRD, scanning electron microscopy with EDX, Raman spectroscopy and UV-vis spectroscopy. The photo-activity of CZTSSe films was assessed by measuring the open-circuit potential (E oc ) values under illumination in an aqueous solution of 0.5 M Na 2 SO 4 . Pure kesterite phase Cu 2 ZnSnSe 3.2 S 0.8 (CZTSSe) with the p-type conductivity and an optical band gap in the range of 1.21-1.31 eV was obtained after the selenization. The CZTSSe films prepared using the DMF as a solvent showed the best phase purity, the lowest density of voids, the highest stability of photoelectrochemical response and the highest power conversion efficiency of fabricated photovoltaic device.

“…In the last decade, copper-based quaternary semiconductor material Cu2ZnSnS4 (CZTS) was widely considered as a most promising absorber layer candidate for low-cost thin-film solar cells, owing to its high absorption coefficient (>10 4 cm -1 ) and optimal bandgap (1.0-1.5 eV) which are ideal properties for the application under solar irradiation. [1][2][3][4] .The compounds such as copper-zinc, tin-sulfur accompanied by non-toxic and friendly environmental solvents have many photovoltaic technology applications. 5,6 The features of these compounds make them suitable for widespread and low-cost applications in the thin-film solar cells.…”

The quadrilateral p-type semiconductor Cu2ZnSnS4 (CZTS) with a direct bandgap of 1.4 to 1.5 eV and a high absorption coefficient in the visible light range, is considered an excellent absorbent layer in the production of solar cells. The application of Cu2ZnSnS4 film absorbent materials is promising in the field of low-cost solar cell production. In this paper, a simple, efficient, controllable, and inexpensive solvothermal method is used to make the CZTS nanoparticles from zinc acetate, copper acetate, tin chloride, thiourea, and hexadecyl amine solvent. The ink was prepared from the CZTS powder and applied by the doctor Blade technique on soda-lime glass. The X-ray diffraction (XRD) and Raman spectroscopy analysis showed that the CZTS synthesis nanoparticles had a pure Kesterite structure. The thermo-gravimetric analysis showed about 12% of the loss weight of CZTS nanoparticles using field emission scanning electron microscopy, energy dispersive spectroscopy, dynamic light scattering, and zeta potential indicated that the synthesized nanoparticles had a strong absorption in the range of 125–477 nm with an average particle size of 300 nm and plate shape. The energy bandgap of CZTS nanoparticles was measured to be 1.49 eV using UV-Vis spectroscopy.
