“…Whereas the spectra that shown in fig 5. (b) has determined without heating obtains emission in the range of 1.504 eV to 1.56 eV with an intense exciton emission at 1.52 eV. The post annealing improves the optical properties of the CZTS nanoparticles by increasing the band gap energies of UVVis to 1.49 eV and PL emission to 1.53 eV which are consistent with the literature value of 1.45-1.6 eV [14][15][16]. …”

Cost effective photovoltaic Cu2ZnSnS4 (CZTS) nanomaterials with kesterite crystal phase were synthesized using a facile solvothermal method. Here ethylene glycol was the solvent and Polyvinylpyrrolidone (PVP) used as capping agent. The obtained CZTS nanoparticles were characterized by means of suitable analytical techniques such as X-ray powder diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), Raman Spectroscopy, Ultraviolet-Visible (UV-Vis) Spectrometer and Photoluminescence (PL) respectively. The XRD results showed that the obtained sample presented as kesterite crystallinity with (112), (200), (220) and (312) planes of the CZTS nanoparticles and the average crystallite size was about 5.7 nm. The morphological investigation results given by the FESEM revealed that the average particle size of the sample was around 129 to160 nm. In addition, the optical observation suggested by both the absorption of UV-Vis and emission spectra of PL showed that the CZTS nanoparticles produced by this solvothermal method has the direct band gap energy within the range of 1.49 to 1.53 eV, which is near the optimal value and it is a dynamic absorber material for the efficient photovoltaic application.

“…Two overlapping peaks of S 2p 3/2 (161.8 eV) and 2p 1/2 (162.5 eV) revealed the -2 valence state in CZTS NPs 27,28. Two peaks were observed in the Cu 2p region at 932.7 eV (2p 3/2 ) and 952.6 eV (2p 1/2 ), which can be attributed to the valance state of copper in CZTS of +1.…”

Cu2ZnSnS4 (CZTS) nanoparticles were synthesized by the precursor injection method using oleylamine as a solvent. Preliminary characterization indicated that the synthesized nanoparticles belonged to the kesterite structure with a bulged sphere-like morphology. Reduced graphene oxide (rGO) was synthesized by an improved Hummers method and was used for nanoparticle functionalization. CZTS nanocrystals were decorated on rGO by two different methods. One was oleylamine-based nanoparticle functionalization, and the other was in situ nanoparticle growth. Transmission electron microscopy analysis of CZTS-functionalized rGO showed that the synthesized nanoparticles were uniformly spread on the surface of rGO sheets. Single phase CZTS nanoparticles were grown on rGO without any impurity phase in the in situ growth. Tuned absorption of the pure CZTS was observed by the decoration of CZTS nanoparticles on the surface of rGO in the visible and UV regions.

“…Many groups have synthesized CTS thin films by several methods which include sputtering [7], SILAR method [15], heating up method [16], sonochemical reaction [17] and solvothermal synthesis [10]. All these methods involve several steps and are prone to the formation of secondary phases.…”
