“… 40 , 41 In the visible range, CZS films were transparent, but in the infrared range, they were much more transparent. These results are comparable with the results reported in refs ( 29 and 33 ) and are found to be better than those reported in refs ( 31 and 32 ). Because of the significant absorption in the UV region, film transmittance in this region is low.…”

Multilayer CdZnS (CZS) thin film was deposited on soda lime glass substrates. After deposition, the films were vacuum and air annealed at 100 °C, 200 °C, 300 and 400 °C for 1 h. Effects of vacuum and air annealing on structural, morphological, optical, and electrical properties of multilayer CZS films with increasing annealing temperature (IAT) were studied. The structural analysis revealed that the films were polycrystalline with hexagonal structure having a prominent/intensive peak along the (002) plane at 300 and 400 °C. The crystallite size of nanoparticles increased from 18.4 to 20.5 nm under air annealing and from 18.4 to 26.9 nm under vacuum annealing, showing the significance of annealing on nanoparticle grain growth. According to morphological analysis, the multilayer technique provides homogeneous film distribution over the substrate. The transmittance graphs of films revealed that it increased up to 92% in the visible and NIR regions under vacuum annealing and up to 52% under air annealing. Vacuum annealing enhanced the band gap energies more significantly than air annealing. The electrical resistivity increased with IAT, showing that structural, morphological, optical, and electrical properties of the multilayer thin films of CZS were strongly dependent on vacuum and air annealing.

“…The strain increases, but the dislocation density decreases in both cases. The results of this study’s structural analysis are comparable with those of prior studies on CZS films made using closed space sublimation, chemical bath deposition, acidic chemical bath deposition, and diluted chemical bath deposition …”

“…Herein, we report on the results of an investigation on various optical properties of a solar cell employing a (Cd x -Zn 1−x )S film as a window layer. Though, there are several reports on similar studies [27][28][29]; however, the originality of the present work lies in the fact that in previous reports the (Cd x -Zn 1−x )S films were deposited by co-evaporation, closed space sublimation and vacuum thermal evaporation, successive ionic layer adsorption and reaction, etc [30] whereas, we herein report the results of detailed studies made on (Cd x -Zn 1−x )S films synthesized by CBD [31][32][33][34]. The results presented in this article are encouraging in the sense that they suggest an easy way to deposit large area, high quality and transparent (Cd x -Zn 1−x )S films to be used as window layers in CdTe/CdS solar cells.…”

An attempt has been made to optimize the Zn concentration in chemically deposited (Cd x -Zn 1−x )S (x =0.2, 0.4, 0.6, 0.8) films on ITO substrate by varying the Cd/Zn composition ratio to enable them to absorb a sizable fraction of solar photons. The phase purity and nanocrystalline character of as-deposited films are established by x-ray diffractometer. Lattice parameters and band-gap values are found to change almost linearly with Cd/Zn composition ratio. The surface morphology supports the nano-crystalline nature of deposited films. The E g values for (Cd x -Zn 1−x )S nanocrystalline films estimated from absorption spectra and corresponding Tauc's plots range from 2.63 to 2.81 eV. The optical behavior in terms of absorption and photoluminescence spectra suggests that these films are suitable for application in photovoltaic devices. The electrical resistivity of different (Cd x -Zn 1−x )S films has been measured as a function of Zn concentration. The efficiency of resultant CdTe/(Cd x -Zn 1−x )S cell is calculated to be approximately 11%.

Summary To overcome the energy shortage and environmental pollution, sunlight is considered an ideal source to solve these problems. Photocatalyst water splitting for H2 production by using solar energy is a favourable technology to deal with the energy shortage, global warming and environmental pollution. During the last few years, sulphide‐based nanomaterial photocatalysts have attained considerable attention due to their comparatively narrow bandgap energy, show excitation in the visible region, at a wavelength of about 600 nm, and thus demonstrate high photocatalytic activities. But semiconductor photocatalysts are easy to be photocorroded due to sensitivity in visible light. The photocorrosion hinder their photocatalytic performance. In order to overcome photocorrosion effects, some modifications in the photocatalysts' surface are required, for example adjusting the metal sulphide structure, depositing anti‐photocorrosion layers or nanoparticles on the surface of semiconductors, which inhibit the photocorrosion attack and sustain the stability. In this review, we discuss progress in the structure, preparation methods, H2 evolution rate, photocorrosion inhibition and energy and environmental applications of different sulphide‐based nanomaterial photocatalysts.
