Photoassisted electrodeposition of a cuprous oxide (Cu 2 O) thin film was studied to find the optimum conditions lowering the deposition temperature. Cu 2 O films were electrochemically deposited on FTO by cycling the electrode potential between 0.0 V and ¹0.8 V (Ag«AgCl), in an aqueous solution. A simple deposition cell was designed to allow simultaneous thermostating and polychromic illumination. Under illumination, the Cu 2 O film deposition occurred, even at a temperature lower than the temperature observed under dark conditions. X-ray diffraction (XRD) analysis confirmed that these films were indexed as cubic symmetric structured pure Cu 2 O (JCPDS: 05-0667), and UV-visible absorption spectra show an optical band-gap energy of 2.5 eV.

“…Self-organization, self-amplification and shape evolution in microcrystalline growth of Cu 2 O has been reported recently [5,6]. Cu 2 O thin films are prepared by many deposition techniques such as thermal oxidation [7], chemical deposition [8], reactive magnetron sputtering [9], pulsed laser deposition [10], plasma evaporation [11], electrodeposition [12,13], and among them electrodeposition is attractive because of its simplicity, low cost and low-temperature process. Wijesundera et al [14] reported electronic states and local structures for Cu ions in potentiostatically electrodeposited Cu 2 O thin films.…”

The structures and the electronic states in electrodeposited semiconductor Cu -O thin films have been investigated for each annealing temperature (T A ) by X-ray diffraction (XD) and X-ray absorption spectroscopy (XAS) near the Cu K edge using synchrotron radiation. The thin films prepared as grown and annealed at T A ≤ 175 °C, 200 °C ≤ T A ≤ 300 °C, T A = 400 °C are characterized mainly by the pure Cu 2 O-type structure, the pseudo-Cu 2 O-type having a superlattice structure, and two phases of Cu 2 O-type and CuOtype structures, respectively, while the film annealed at T A = 500 °C is single-phase CuO-type. The XAS spectra suggest that there is a structural phase transition occurring at about 400 °C, which induces a modulation of the local structure around Cu ions observed in the extended X-ray absorption fine structure (EXAFS) and the occupational electronic band states of Cu-4p localized just above the Fermi level, taken from X-ray absorption near edge structure (XANES). The open-circuit voltage suggests that the photosensitivity of the Cu -O thin films strongly depends on the annealing treatment and shows a crossover from an n-type to a p-type semiconductor.

“…The physical properties like mechanical, electrical, magnetic and optical of thin films may differ from those of the bulk material and are mainly used in deposition on preferred substrate for electronics parts and superconductors 3 . In recent years, researchers have focused on cadmium oxide (CdO) for its applications, specifically in the field of optoelectronic and photovoltaic parts such as solar cells 4 . Cadmium oxide (CdO) show high transparency in the visible region of solar spectrum and has high electrical properties which were represented low ohmic resistance 5 6 .…”
