“…This result is in good agreement with those reported by Shu-wen et al , 29 who used Na-doped ZnS, and Derbali et al who used Ni-doped ZnS. 30 Therefore, it is possible to replace CdS in CIGS solar cells by these films. 31 In all transmittance spectra, there is an absence of interference fringes due to weak multiple reflections at the interface.…”

“…The additional weak band appearing at 610 nm (orange band) may be due to the band edge luminescence of semiconducting interface. Such phenomenon of band edge luminescence, typical of ternary semiconductor is well known and extensively reported in the literature [40,41]. The sharp peaks around 636 nm and 647 nm occur due to the presence of sulfur vacancies and stimulated centers of Ni interstitial states associated with the nanostructures of Bi.…”

In this report, ternary semiconducting NixBi2−xS3(x = 0.2 M and 0.5 M) thin films were synthesized in situ for the first time by a chemical bath deposition technique at different bath temperatures (60 °C, 70 °C and 80 °C). The effects of concentration and deposition temperature on the deposited films were studied by combining the results of structural, morphological, optical and electrical analyses. The growth of NixBi2−xS3 films with good crystalline nature and interconnected grain arrangement takes place due to increasing the concentration of Ni2+ ions in bismuth sulfide matrix. EDS result confirmed the stoichiometry of NixBi2−xS3 formation. Wettability test demonstrated that the surface of the film was hydrophilic in nature. The optical absorption spectra revealed that the bandgap Eg of the x = 0.5 M film deposited at 70 °C was about 1.36 eV. Current-voltage (I-V) characteristics of the x = 0.5 M film deposited at 70 °C were studied under X-ray radiation and dark condition. An X-ray detection sensitivity analysis showed that the detection sensitivity is optimum when the bias voltage applied across the film is low (~0.9 V). These findings reveal that the film with x = 0.5 M deposited at 70 °C can be used as an efficient low cost X-ray sensor.

“…38 The oscillations in the spectra are due to the interference in the TiO 2 film by the reflections at the air-TiO 2 and TiO 2 -substrate interfaces. [39][40][41] The band gap (E g ) for the films is determined from the optical transmittance spectra by using the Tauc model (αhυ) n versus photon energy plot: [42][43][44]…”

In this work, the transparent TiO 2 photoelectrodes have been synthesized by the sol-gel method and the dip-coating technique, incorporating three rheological agents as porous template -Triton X-100, polivinilpirrolidone (M.W. 10000) and Pluronic F-127 into the TiO 2 sol for the application in dye--sensitized solar cells. Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, m-lines and UV-Vis spectroscopy analyses were carried out to examine the chemical composition, structure, morphology, thickness and optical transmittance of the TiO 2 photoelectrodes. Impedance spectroscopy was carried out to analyze the cells' behaviour. An average energy conversion efficiency of 1.04 % was achieved using triton as a modifier of the transparent TiO 2 film, obtaining a thickness about 1.21 µm, a crystallite size of about 7 nm in the anatase phase and the porosity of about 53.4 %. Triton proved to be efficient for obtaining transparent and porous semiconductor films, while increasing the photoelectrochemical device's performance.
