ZnS films have been deposited on glass substrates by chemical bath deposition (CBD). The optical and structural properties were analyzed by UV-VIS spectrophotometer and X-ray diffraction (XRD). The results showed that the prepared thin films from the solution using N2H4 as second complexing agent were thicker than those from the solution without adding N2H4 in; this is due to using second complexing agent of N2H4, the deposition mechanisms change which is conductive to heterogeneous deposition. When using N2H4 as second complexing agent, the crystallinity of ZnS thin films improved with a significant peak at 2θ=28.96°which can be assigned to the (111) reflection of the sphalerite structure. The transmittances of the prepared films from the solution adding N2H4 in as second complexing agent were over 85%, compared to those from the solution without N2H4 (over 95%). The band gaps of the ZnS films from the solution using N2H4 as second complexing agent were larger (about 4.0eV) than that from those from the solution without N2H4 (about 3.98eV), which indicated that the prepared ZnS films from the solution adding N2H4 in as second complexing agent were better used as buffer layer of solar cells with adequate optical properties. In short, using N2H4 as second complexing agent, can greatly improve the optical and structural properties of the ZnS thin films.

In the present work, zinc sulfide thin films were deposited on glass substrates by sol–gel process with different coating speeds 3600, 4800, 6000 and 7200[Formula: see text]rpm. Zinc acetate (Zn(CH3COO)[Formula: see text]H2O) and thiourea (CH4N2S) were used as precursors. Two-methoxyethanol and monoethanolamine were used as solvent and stabilizer, respectively. The optical properties of ZnS thin films such as refractive index, extinction coefficient, dielectric function and optical band gap energy of the films were obtained by spectroscopic ellipsometry (SE) analysis method in the wavelength range of 300–800[Formula: see text]nm. The incidence angle of the layers was kept at 70∘. The measured SE parameters [Formula: see text] and [Formula: see text] are fitted against the designed model by minimizing the mean square error (MSE). Considering the data obtained, it can be deduced that the optical properties of ZnS films are highly influenced by rotation rates. The extinction coefficients of the films were increased with increasing rotation rates of the films. From these results, it is found that the energy gap of the ZnS films increases with increasing rotation rates of the films in the range of 3.13–3.20[Formula: see text]eV.
