“…It should be noted that stoichiometry of studied films is some improved during the increasing of dispersed precursor volume. Also, the obtained ratio γ CZTS_1 = (0.80-0.84) in CZTS films deposited at precursor dispersion with volume of V s = 2-3 ml is close to the optimal values necessary to develop SCs with high solar energy conversion efficiency (γ CZTS_1 = (0.8-0.9), γ CZTS_2 = (1.1-1.2)) [40,42]. For film obtained by dispersion precursor volume of 3 ml for this requirement corresponds the next ratio-γ CZTS_2 = 1.2.…”

The paper presents the investigation on the influence of substrate temperature T s and the sprayed initial solution volume V s on structural, substructural, optical properties, and elemental composition of ZnO and Cu 2 ZnSnS 4 (CZTS) films as well as state-of-the-art of studying the Cd 1−x Zn x Te (CZT) films obtained by spray pyrolysis technique. The singlephase nanocrystalline ZnO films with average crystallite size of D C = 25-270 nm and thickness of d = 0.8-1.2 μm can be deposited at substrate temperatures of T s > 473 K. The continuous CZTS films with optimal thickness (d = 1.3 μm) for application as absorber layers in solar cells were deposited at the sprayed initial precursor volume of V s = 5 ml. The increase of the substrate temperature up to 673 K caused the significant improvements in the stoichiometry of ZnO films. The optimal stoichiometry ratio of CZTS films for application in solar cells was obtained at V s = 3-4 ml. Optical study of ZnO films showed that these films have a high-transmission coefficient values of T = 60-80%. To the best of our knowledge, there is the lack of works devoted to the study of CZT films obtained by spray pyrolysis technique.

“…The value of D increases with increase of annealing temperature. The dislocation density, lattice strain, micro strain, and stacking fault for the present series samples are extracted from d = 1/D 2 (Sathyamoorthy et al 2006;Sharma et al 2011;Touati et al 2014;Bindu and Thomas 2014), e = b/ 4 9 tanh (Thool et al 2014), e = b 9 cosh/4 (Sathyamoorthy et al 2006;Sharma et al 2011) and SF = 2p 2 /45H(3tanh) (Touati et al 2014;Thool et al 2014), respectively, and their values are given in Table 1. From Table 1 we notice that the dislocation density, lattice strain, micro strain, and stacking fault for the annealed samples decrease with the increase of annealing temperature.…”

The nanocrystalline BaFe 12 O 19 powders were obtained from citrate sol-gel combustion-derived powder upon annealing at 800-1100°C, and explored their structural, micro-structural, optical and magnetic properties. The thermal decomposition of citrate sol-gel combustion product was verified by means of thermogravimetric and differential thermal analysis. Structural identification of the citrate sol-gel combustion powder and annealed samples were investigated by powder X-ray diffraction. Though the combustion product exhibits cubic spinel phase material, the annealed powder yields good quality nanocrystalline hexagonal BaFe 12

“…Nevertheless, the non-toxicity and abundance of the elemental composition of copper-zinc-tin-sulfide (CZTS) makes it a very fascinating alternative of Cu(In,Ga)Se 2 (CIGS) and CdTe solar cells which suffer from the deficiency and toxicity of the elements. CZTS is reported to have a band gap of about 1.5 eV and an absorption coefficient of about 10 4 Cm -1 which makes it highly attractive as a solar cell material [1][2][3]. The CZTS absorber layers are prepared by various formation methods, such as thermal evaporation [4,5], e-beam evaporation with a post sulfurization [6], sputtering [7][8][9], pulsed laser [10], electrochemical deposition [11][12][13] and spin coating methods [14].…”

Copper zinc tin sulfide (CZTS) thin film was synthesized on soda lime glass substrate by using spin coating method. The synthesized CZTS thin film showed maximum absorption coefficient of 0.193 × 10 4 cm-1 and maximum extinction coefficient of 0.011. The direct optical band gap, Urbach energy and steepness parameter of the synthesized CZTS thin film were 1.52 eV, 0.52 eV and 0.05 respectively. The CZTS thin film was found to be polycrystalline tetragonal in nature. The scanning electron microscopy (SEM) revealed that the texture structure was formed for the CZTS thin film.
