“…Zinc oxide (ZnO) is an n-type semiconductor highly employed in different devices, such as sensors, biosensor, solar cells, supercapacitor and catalysis fields [1][2][3][4] thanks to its interesting properties, including its wide band gap of 3.37 eV [4], resistivity control, high electrochemical stability, good electron transfer features and transparency in the visible wavelength region [1] in addition to being an abundant non-toxic and low-cost material.…”

In this paper, ZnO electrodeposition was studied with the presence of graphene oxide (GO) exploited as a possible structure-directing agent. The effect of deposition potential and duration on the morphology and structure of ZnO was analyzed. The morphology and structure of the hybrids was analyzed by Raman spectroscopy, X-ray diffraction (XRD), and Scanning Electron Microscopy (SEM). The Raman results indicate a successful modification of ZnO with GO sheets and a hybridization threshold of 10 mg L−1 by the evolution of the defect related band of ZnO at 580 cm−1. The morphology results show that a low GO content only slightly influences the morphology and orientation of ZnO nanostructures while a high content as 10 mg L−1 changes the morphology in nanoplates and growth orientation to lateral. The results show that while GO participated in the deposition reaction, it has a two-fold role, also by structure-controlling ZnO, indicating that the approach is valid for the use of GO as a structure-directing agent for the fabrication of ZnO nanostructures by electrodeposition with varying morphologies and orientations.

“…The semiconductor heterojunction solar cells (SCs) attracted increased interest because of the advantages such as high efficiency [26], easy fabrication, and low cost [27]. Among the different heterojunction solar cells such as intrinsic thin-layer, silicon, CdTe/CdS, CIGS/CdS [28], it was indicated that the ZnO/Cu 2 O [29,30] ones show a great absorption in the UV-visible region [31], their components being non-toxic and earth-abundant [32]. Furthermore, the alignment of ZnO/Cu 2 O heterojunction allows the separation and transportation of electro-hole pairs [33,34].…”

Electrodeposition of ZnO/Cu2O Heterojunctions on Ni-Mo-P Electroless Coating

et al. 2020

Electroless Ni-Mo-P coatings were deposited onto ceramic tiles in order to be employed as electrodes for the electrodeposition of ZnO and Cu2O heterojunction layers. Varying conditions, such as duration, annealing of the electroless coating and applied potential, and duration for ZnO electrodeposition were studied in order to optimize the properties of the ZnO/Cu2O heterojunctions toward improved photoelectrical performance. The coatings were evaluated in terms of morphology, crystalline structure, and by electrochemical and photoelectrical means. The obtained results indicated that a prolonged annealing treatment at low temperature is beneficial to improve the roughness and electrical conductivity of the Ni-Mo-P coating to further enhance the electrodeposition of ZnO. The morphology analysis revealed continuous and homogeneous Ni-Mo-P coatings. The formation of cube-like Cu2O crystals with larger grain size was induced by increasing the deposition duration of ZnO. The properties of ZnO layer are much improved when a higher cathodic potential is applied (−0.8 V) for 1 h, resulting in optimum photoelectric parameters as 1.44 mA·cm−2 for the JSC and 760.23 µV for the VOC value, respectively, for the corresponding heterojunction solar cell.
