Herein the synthesis of ZnO nanorods (NRs) by means of the one‐ and two‐step electrochemical deposition (ECD) process is focused upon. A comparison of the crystal structure, morphology, optical properties, and photoelectrocatalytic (PEC) activities of nanostructured ZnO cultivated by the two methods is conducted. X‐ray diffraction (XRD) analysis reveals that all samples annealed at 300 °C are polycrystalline and have a hexagonal (wurtzite) structure and significant improvement in the crystallinity of the sample deposited by the two‐step process. The morphological characterizations show that the NRs are well hexagonal and well oriented in the same sample. The optical spectra show a transmittance higher than 70% and direct bandgaps of 3.12 and 3.04 eV for the samples synthesized by one‐step and two‐step electrodeposition, respectively. The PEC properties of the films obtained are studied and reveal an efficient and rapid rhodamine B (RhB) azo dye degradation. In addition, the scavengers of reactive species as well as the kinetics during degradation are also studied and show that the superoxide radicals contribute significantly in degradation.

Dye-sensitized solar cells (DSSCs) are a feasible option for photovoltaic energy. Zinc oxide is an n-type semiconductor employed as photoanode on DSSCs. ZnO thin films were electrodeposited to study the effects of different potentials applied during deposition. SEM images, XRD and UV-Vis analysis were conducted to reveal the morphologic, structural and optical properties of the films at three potentials. DSSCs were assembled and the photovoltaic parameters were obtained through J-V plots. DSSC with 0.031% of efficiency was demonstrated at -1.4 V of deposition potential.

Abstract. ZnO thin layer has a broad potential application in electronic and optoelectronic devices. In this study, vertically align ZnO layers were deposited on ITO glass using wet chemistry method. The seed layers were prepared using electrodeposition technique at 3°C. The growing process was carried out using chemical bath deposition at 90°C. To improve the structural properties, two different hydrothermal treatment variations were applied separately. From the experiment, it is shown that the hydrothermal process using N2 gas has given better results, compared to the conventional treatment.
