“…Fourier Transform Infrared Spectroscopy study is carried out to identify and analyze the different functional groups present in the prepared NiS films over the wave number range between 500 cm -1 and 4000 cm -1 (see Figure 2 (a)) The weak bands or shoulders observed at 713, 826 and 903 cm -1 were related to the symmetrical stretching modes of NiS, which could be due to microstructural formation of NiS in the films and are in agreement with the data reported in the literature (17) . The band at 1523 and 1685 cm -1 corresponds to -COOH asymmetric stretching vibration.…”

Objectives: To study the influence of deposition time on the physical behavior of NiS films formed by chemical bath deposition (CBD). Methods: Polycrystalline NiS thin films were deposited by using CBD method on glass substrates by varying the deposition time in the range of 60-150 min with the other growth conditions kept constant. The physical properties were measured using an X-ray diffractometer, Scanning Electron Microscopy with Energy Dispersive X-ray analyzer, and Fourier transform infrared spectra. Finally, the optical and electrical properties of the films were analyzed by using UV-Vis spectrophotometer and linear four-probe point method respectively. Findings: The X-ray Diffraction (XRD) studies showed polycrystalline nature of the films with hexagonal structure, confirmed by the Rietveld refinement analysis. The calculated crystallite size varied from 6 nm to 19 nm with the increase in deposition time. The EDS analysis revealed the stoichiometry of Ni and S in the samples. The optical bandgap decreases from 2.06 eV to 1.93 eV with the increase in deposition time. The films synthesized using a deposition time of 120 min at 80 • C showed a high electrical conductivity of 48.3 S/cm at room temperature with activation energy of 0.16 eV. Novelty: NiS thin films were deposited by the CBD method using different deposition times varying from 60 min. to 150 min., keeping the bath temperature constant at 80 • C for the first time. The Rietveld refinement analysis was the first of its kind, reported on the structural evaluation of NiS layers. These films were formed using eco-friendly materials adding value to the solar cell application.

In this work, we prepared thin films of nickel sulfide by spray pyrolysis on substrates of the glass at temperature of 300°C. The solution used is a mixture of nickel acetate and thiourea as a source of nickel and sulfur respectively, acetic acid was used as a complexing agent, and then heated the resulting layers in an ordinary furnace at 300°C at different times of 1h, 2h and 3h to study the annealing time effect on the physical and chemical properties. The characterization methods used indicate remarkable changes in the structural, electrical, morphological and optical properties of NiS films under annealing time. The results obtained have shown that the prepared NiS films contain good crystallization, dense morphology, good stochiometric ratio and high conductivity, and these specifications make them a potential candidate as electrode material for application in super-capacitors.

“…A wide range of devices, such as photovoltaics, electronics, sensors, and other things, made use of metal sulphides. [14,15] Due to their elevated theoretical capacity and the presence of more than two valence states of the metal, sulphide compounds frequently exhibit optimized capacitance. [16] Such an application has been exhibited by researchers.…”

Neodymium Indium sulphide (Nd4In5S13) photoactive electrode was produced by spin‐coating for photoelectrochemical cell. The photoactive electrode is analysed for its crystalline, structural and elements makeup in addition to its optical and electrical responses. A 56 nm sized orthorhombic crystallite was found and geometrical compact structures were observed. The presence of chief elements with core levels of In3d, Nd4d and S2p were detected. The bandgap energy was found to be 4.1 eV. Electrochemical investigations were performed to evaluate the photoactive efficiency of the electrode. Photo‐cyclic voltammetry present a specific capacitance under illumination to be 570 Fg−1, as contrasting to 481 Fg−1 when in dark. A photocurrent density of 282 mA cm−2 was obtained from photo‐linear sweep voltammetry. It had also been discovered that the transient chronoamperometry provided a photocurrent density of 46.1 mA cm−2. Whereas electrical impedance spectroscopy presented internal resistance (Rs) to be 232 Ω. All scan rates show an increase in the specific capacitance of photo‐electrode when illuminated. The research created an effective photo‐electrode for renewable energy structures. It can be posited that the study presented a pragmatic photoelectrode, which had the potential to be employed in sustainable energy frameworks, including but not limited to photovoltaics, supercapacitors, and photoelectrochemical solar cells.
