“…But the electrodeposition technique is an inexpensive, simple and low temperature method that could produce films of high quality for the device applications such as heterojunction devices, switching devices etc. [6]. However, it is known that it is difficult to obtain the active layer available to solar cells with high efficiency by this method, because the electrodeposited films consists of very small crystallites [7] and hence many surface states which act as a recombination centers are present [8].…”

Indium Selenide (InSe) thin films were deposited from a mixture of Indium chloride and selenium dioxide in aqueous solution by electrodeposition technique on Indium Tin oxide coated glass substrates. The effects of the parameters during deposition such as current density, deposition potential versus saturated calomel electrode, pH value and concentration of source material were studied. X-ray diffraction studies were carried out on the films to analyze the microstructure using an x-ray diffractometer and were examined by RAMAN spectroscopy. The Raman peak position did not change much with chemical concentrations. Raman scattering due to the (LO) phonon was observed at 211 cm -1. Optical absorption studies were performed with a double beam ultra violet-visible -NIR spectrophotometer in the wavelength 300 -1100 nm. The surface morphology of the layer was examined using a scanning electron micrograph. The composition of the films was studied using an Energy Dispersive Analysis by X-Rays (EDAX).

“…CuInSe 2 thin film with a direct band gap of about 1.0 eV [1][2][3] and a large absorption coefficient in the range of 10 4 -10 5 cm --1 [2,4] is one of the promising absorbing materials for heterojunction solar cells. CuInSe 2 thin films have been prepared by various techniques, viz., close-spaced vapour transport [5], electrodeposition [6][7][8][9], three-source evaporation [10], selenization [11], molecular beam deposition [12], spray pyrolysis [13], pulsed excimer laser ablation [14], flash evaporation [15] and chemical bath deposition [16][17][18][19][20].…”

Subject classification: 68.55.Jk; 68.55.Nq; 78.66.Li; S8.12 Copper indium diselenide thin films of different thicknesses were prepared by the chemical bath deposition technique onto well-cleaned glass substrates at room temperature. The thickness of the deposited films has been determined by gravimetry. The structural characterization was carried out by X-ray diffraction and scanning electron microscopic studies. These studies confirm the polycrystalline nature of the films with chalcopyrite structure. The structural parameters such as lattice constants, axial ratio, tetragonal distortion, crystallite size, dislocation density and number of crystallites per unit area have been evaluated. The composition of the various constituents in CuInSe 2 films has been determined by energy dispersive X-ray analysis. The optical properties have been studied in detail in the wavelength range 4000-14500 A and the optical band gap has been found to be direct and allowed.

“…Electrodeposition has been studied as an alternative because it offers a convenient and an inexpensive synthetic way for the preparation of cadmium chalcogenides from aqueous or nonaqueous solutions of the appropriate precursors [34,35]. Electrodeposition has the advantage of being a low-temperature method so it can be used in systems containing thermal unstable materials.…”

Electrodeposition is a key technique to create nanostructures of metals and inorganic semiconductors. Unlike the electrodeposition of metals, the fabrication of nanostructures of binary semiconductors with desired crystallinity and stoichiometry is not straightforward. Herein, we describe the optimization of conditions for the electrodeposition of stoichiometry and crystalline cadmium selenide (CdSe), cadmium telluride (CdTe), and CdSe/CdTe nanostructures. We first identified the optimal conditions for the electrodeposition of CdSe and CdTe with 1:1 stoichiometry by varying the concentrations of Cd 2+ and SeO 2 (or TeO 2 ) and optimizing the electrodeposition potential. We then optimized the pH of the electrolysis solution for increasing the crystallinity of the deposited structures. We then tested the efficacy of our electrodeposition conditions on substrates such as gold, nickel, and indium tin oxide. We used the optimized conditions to electrodeposit semiconductors within anodic aluminum oxide (AAO) membranes to create oriented CdSe and CdTe nanorods, CdSe/CdTe segmented nanorods, and CdSe/CdTe coaxial nanorods. These optimized electrodeposition conditions add a valuable tool in the synthetic toolbox for the synthesis of crystalline semiconductor nanostructures for solar cell applications.
