“…There are several peaks corresponding to ZnO was observed in addition to substrate peaks indicating that the ZnO thin film was successfully deposited. This result is consistent with the previously reported [5,8,11]. Moreover, no other peaks were seen on the XRD patterns.…”

Abstract. Zinc Oxide (ZnO) has been successfully electrodeposited on a fluorine doped tin oxide (FTO) coated glass substrates using a simple aqueous solution containing zinc nitrate hydrate by low temperature galvanostatic electrolysis. The solution temperature of zinc nitrate hydrate was varied from 60°C to 75°C in order to investigate the effect of solution temperature on electrodeposit-ZnO thin film. The properties of ZnO film were investigated by X-ray diffraction (XRD), Field-Emission Scanning electron microscope (FE-SEM) and Atomic force microscopy (AFM). The solution temperature shows a significant effect on structural and morphological of deposit-ZnO. The XRD patterns exhibited the increment of (002)-ZnO peak when the solution temperature increased and the highest peak was observed at 75°C. The morphology of ZnO was changed from planar to nanopillar with the solution temperature. In conclusion, ZnO nanopillar with an excellent structural properties was obtained at solution temperature of 75 o C.

“…Electrodeposition 14) has many advantages such as low cost, simple processes, and controllable thickness and structure of the films. Many studies have reported nanostructured Cu 2 O deposition, 2,15,16) particle shape, 3,11,12,17) deposition temperature, 18,19) and film orientation control 20) using electrodeposition methods. The electrodeposition of the Cu 2 O film was usually achieved at temperatures 5,10,2023) higher than room temperature to overcome the activation energy.…”

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.

“…Several groups have shown predictable effects of the crystallite orientation of the Cu 2 O films for improvements of the carrier mobility and photoelectric property [13,17,23,33]. It is well known that face-centered cubic (fcc) metals such as Pt tend to form (111) oriented film preferentially on the surface of amorphous materials by a self-assembly.…”

“…Among several Cu 2 O formation methods, such as thermal oxidation [6 -12], electrodeposition [13][14][15][16][17][18][19][20][21] and sputtering deposition [22][23][24][25][26][27], the highest conversion efficiency was obtained by the thermal oxidization method. Since the thermal oxidation progresses under a thermal equilibrium state of the Cu 2 O phase [28], it seems to be an ideal formation method.…”

Room temperature sputtering deposition and re-crystallization of the deposited thin films by rapid thermal annealing have been evaluating in detail as a formation method of Cu 2 O active layer for solar cells, which minimize thermal budget in fabrication processes. Single phase polycrystalline Cu 2 O films were obtained by a magnetron rf sputtering deposition and its crystallinity and electrical characteristics were controlled by the annealing. Hall mobility was improved up to 17 cm 2 V -1 s -1 by the annealing at 600°C for 30s. Since this value was smaller than 47 cm 2 V -1 s -1 of the film deposited under thermal equilibrium state using pulsed laser deposition at 600°C, some contrivances were necessary to compensate the deficiency. It was understood that the sputter-deposited Cu 2 O films on (111)-oriented Pt films were strongly oriented to (111) face also by the self-assembly and the crystallinity was improved by the annealing preserving its orientation. The sputter-deposited film quality was expected to become equivalent to the pulsed laser deposition film from the results of X-ray diffractometry and photoluminescence.
