“…Copper selenide induces much interest since it has been broadly used as solar cell applications 16 . CuSe thin films can be deposited by different techniques such as physical vapour deposition, pulse laser evaporation, electro deposition, spray pyrolysis, metal organic vapour phase epitaxy (MOVPE)/metal organic chemical vapour deposition (MOCVD), screen printing, successive ionic layer adsorption reaction (SILAR), RF sputtering, and chemical bath deposition (CBD) [17][18][19][20][21][22] . Thin film heterojunctions solar cells play asignificant role as low cost, large area and high…”

Copper selenide (CuSe) thin films were prepared by chemical bath deposition (CBD) method. X-ray diffraction (XRD) analysis was used to study the structure and crystallite size of CuSe thin film. The grain size and the surface morphology were studied using Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). The optical properties were studied using the UV-Visible transmission spectrum. The dielectric properties of the synthesized CuSe thin films were studied at different frequencies and different temperatures. Further, electronic properties, such as valence electron plasma energy, average energy gap or Penn gap, Fermi energy and electronic polarizability of the CuSe thin films were determined. The AC electrical conductivity study revealed that the conduction depended both on the frequency and the temperature. The temperature dependent conductivity study confirmed the semiconducting nature of the films. Photoconductivity measurements were carried out in order to ascertain the positive photoconductivity of the CuSe Thin films. This paper covers what all has been stated above besides discussing the results of I-V characteristics.

“…The techniques adopted for deposition of this metal chalcogenide vary from reaction of metallic copper with selenium dissolved in a benzene medium [1] or an aqueous medium [2], flash evaporation [3], vacuum evaporation [4][5][6][7], melting of Cu and Se [8,9], and electrodeposition [10], to the simplest method of chemical bath deposition (CBD) [11][12][13][14][15][16][17][18][19][20][21][22]. Copper selenide exists in widely differing crystallographic structures depending on the method of preparation even at room temperature.…”

A low cost chemical bath deposition (CBD) technique has been used for the preparation of Cu 2-x Se thin films on glass substrates. Structural, electrical and optical properties of these films were investigated. X-ray diffraction (XRD) study of the Cu 2-x Se films annealed at 523K suggests a cubic structure with a lattice constant of 5.697Å. Chemical composition was investigated by X-ray photoelectron spectroscopy (XPS). It reveals that absorbed oxygen in the film decreases remarkably on annealing above 423K. The Cu/Se ratio was observed to be the same in as-deposited and annealed films. Both as-deposited and annealed films show very low resistivity in the range of (0.

“…Various applications such as solar cells [2], optical filter, superionic conductors [3,4], thermoelectric converters [5], photo-detectors, electro-conductive electrodes, microwave shielding coating [6], photovoltaic cells and Shottkydiodes are associated with these metal chalcogenide compound [1,7,8]. These have resulted in a great deal of research being done to study the production and characterization of the chalcogenide thin films [9].…”

Abstract:Thin films of copper selenide (CuSe) were physically deposited layer-by-layer up to 5 layers using thermal evaporation technique onto a glass substrate. Various film properties, including the thickness, structure, morphology, surface roughness, average grain size and electrical conductivity are studied and discussed. These properties are characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), ellipsometer and 4 point probe at room temperature. The dependence of electrical conductivity, surface roughness, and average grain size on number of layers deposited is discussed.
