“…Thin layers of copper sulfide (Cu x S, 1 x 2), due to their special optical and electrical properties, have received much attention, as one of chalcogenide semiconductors, in many applications such as thermoelectric cooling materials [1], sunlightabsorbing layers [2][3][4][5][6][7], electro-conductive coatings [8] and chemical sensors [9]. These properties are often dependent on the type of structure and stoichiometry of the chemical composition.…”

In this study, physical properties of copper sulfide thin films deposited on glass substrates by spray pyrolysis method at different temperatures (260°C, 285°C and 310°C) were investigated. The influence of annealing time on the physical properties of grown layers was also studied. According to FESEM images, the sizes of the compact copper sulfide grains were varied from about 100 nm to 60 nm. Hall effect and resistivity measurements confirmed that all samples had p-type conductivity. The XRD patterns showed that, together with the dominant digenite phase (Cu 1.8 S) in all samples, the copper-rich phases also appeared as a result of increasing substrate temperature. The optical UV-Vis spectra analysis showed that due to increasing the substrate temperature, the band gap of the layers was reduced from about 2.4 eV to 2.0 eV. We found that as a result of annealing at 400°C for 1.5 h in Ar atmosphere, the sample which was initially grown at 310°C with the highest copper content, totally transformed into the polycrystalline monoclinic chalcocite phase (Cu 2 S) with 3D nanoporous architecture.

“…The CdS sensitized solar cells are attracting the researches for exploring the materials elaborately (Yan et al, 2013;Senthamilselvi et al, 2013). The noticeable efficiency of the CdS makes it to be useful as a window layer in solar cell materials with several other semiconductor materials such as ZnS (Hwang et al, 2012), Cu 2 S (Lindroos et al, 2000), FeS (Manikandan et al, 2014a), ZnSe (Raj et al, 2012), CdTe (Girish Kumar and Koteswara Rao, 2014) and CdSe (Deshpande et al, 2013). The CdS films is deposited by several coating techniques viz., chemical bath deposition (Rusu et al, 2003;Obaid et al, 2013;Oliva-Aviles et al, 2010), spray pyrolysis (Ikhmayies et al, 2013), spin coating (Seon et al, 2009), MOCVD (Yoon et al, 2006).…”

Abstract:The equimolar concentration thin films of Cadmium Sulfide (Cd x S x ) with the complexing agent TEA were deposited on a glass substrate by the SILAR technique. The crystalline nature with face centered cubic crystal system of the CdS films is determined from Xray diffraction analysis. The broadened diffraction peaks indicated nano sized particles of the film materials. The surface morphology of the films was studied by SEM analysis. The Energy Dispersive Analysis of X-ray (EDAX) plot confirms the equimolar composition of Cd and S ions in the film materials. Surface topography of the film was studied by AFM. The optical characteristic of absorbance, transmittance and band gap was analyzed by UV-visible spectra. The band gap energy of the material was observed as 2.18 eV and chemical bonding was studied by FT-IR spectral analysis.

In this study, CuS thin films were deposited on glass substrates by SILAR method with different pH, dipping time and dipping cycles. For the first time, response surface methodology was used for optimization CuS thin film coating parameters. 5-level-3-factor central composite design was employed to evaluate the effects of the deposition parameters (pH, dipping time and dipping cycles) on the optical band gap of the films. The significant level of the main effects and the interactions were investigated by analysis of variance. The morphological, structural and optical properties of the films were investigated by SEM, XRD and UV-Vis. The optimum pH, dipping time and dipping cycles were found to be 11.5, 31 s and 15 cycles, respectively. Under these conditions, the experimental band gap of CuS was observed as 2.18 eV which was well in close agreement with predicted value (2.11 eV) by the model. Quality of the film was improved after chemometrics optimization.
