“…Using equation 1, the average sizes of as-deposited CdS thin films derived from the data are estimated. The different values, as displayed in Table 1, are in good agreement with other results carried out in literature (Memarian et al, 2017;Priya et al, 2018). The surface morphology images for the CdS films are shown in Figure 2.…”

Cadmium sulfide (CdS) is one of the most promising electrontransporting materials in CdTe-based solar cells. In the present study, we use chemical bath deposition (CBD) technique to synthesize cadmium sulphide (CdS). The influence of solution pH level on the structural properties of CdS films was studied using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS). X-ray diffraction (XRD) analysis revealed that the as-grown CdS thin films were polycrystalline in nature, consisting of hexagonal wurtzite phase. SEM images showed grains uniformly distributed over the surface of the substrates, and EDS results demonstrated that the composition analysis of Cd:S ratio is close to 1:1. These CdS layers are expected to enhance the current, resulting in best photovoltaic performance for CdTe-based solat cells.

“…Nowadays, nanotechnology has been applied in many fields, including semiconductor devices with better efficiency and tunability. The science and technology of nanomaterials have created great excitement and expectations in the last few years (Priya et al, 2018). In recent years, scientists discovered that the semiconductor materials in nanometer-size can exhibit different properties from those of the corresponding bulk semiconductors.…”

The present research demonstrates a detailed discussion for the effect of annealing temperature on the structural transformation and surface morphology of the CdS nanoparticles synthesized using the precipitation method without surfactant in KOH alkaline medium. The annealing temperature used was in the range of 160 – 480 oC. The samples structural, functional group and morphological properties were investigated by using XRD, FTIR and SEM techniques. XRD analysis reveals that the CdS has gradually been transformed from the pure cubic to hexagonal polycrystalline structure as well as improved crystallinity upon increasing the temperature. Besides, the parameters of average crystallite size and dislocation density were calculated using the established Debye- Scherrer equation. The average crystallite size was in nano-dimension and increases gradually with temperature. The FTIR spectra indicate that the characteristic vibration band of CdS emerged in the lower wavenumber region of 650 and 500 cm-1, and the band becomes stronger as the temperature rises. Also, the SEM images demonstrate that the CdS exhibits uniform spherical morphology and the particle size grows larger at elevated temperatures. The improved crystallinity and structural properties tuning ability against temperature allows beneficial optical applications as solar cells, photocatalysts, non-linear optics, light emitting diodes and optoelectronic devices.

“…Then, to find the value of the thermodynamic parameter, the obtained values must be divided by 15, since the model consists of 15 pairs of metal and chalcogen atoms. The sphalerite structure of CdS is stable at low temperatures and has a lattice parameter а=5.825 Å [35]. In this paper the value of the lattice constant is obtained 6.1455 Å, which is relatively higher than the data [4] using the LDA -5.816 Å та GGA -5.990 Å, due to the use of additional atoms for compensation of broken bonds.…”

Thin-film CdS layers obtained by the open evaporation method in vacuum are considered and cluster models for calculation of crystal, band structure and thermodynamic parameters are proposed. The thermodynamic parameters of the formation energy ΔE, enthalpy of formation ΔH, Gibbs energy ΔG, entropy ΔS and specific heat capacities at constant pressure and volume for cubic and hexagonal crystallographic modifications are determined. The stable crystal structure for cadmium sulfide was determined from the analysis of Gibbs energy temperature dependences for the sphalerite and wurtzine phases.
