“…A V OC around 700 mV was further revealed at low power illumination conditions [87]. Additional reports investigating the ZnO/ZnSe core-shell NW heterostructures by other deposition techniques claimed that the type II interfacial transition has been demonstrated, but only by focusing on absorption measurements [88] [89].…”

As an abundant and non-toxic wide band gap semiconductor with a high electron mobility, ZnO in the form of nanowires has emerged as an important electron transporting material in a vast number of nanostructured solar cells. ZnO nanowires are grown by low-cost chemical deposition techniques and their integration into solar cells presents, in principle, significant advantages including efficient optical absorption through light trapping phenomena and enhanced charge carrier separation and collection. However, they also raise some significant issues related to the control of the interface properties and to the technological integration. The present review is intended to report a detailed analysis of the state-of-the-art of all types of nanostructured solar cells integrating ZnO nanowires, including extremely thin absorber solar cells, quantum dot solar cells, dye-sensitized solar cells, organic and hybrid solar cells, as well as halide perovskite-based solar cells.

Pure and Ag-decorated ZnO nanowires (ZnO NWs) were grown by electrodeposition technique onto ITO conductive glass substrate. A new contribution to the knowledge of Ag dependence of morphological, structural, optical properties is reported, as well as the electrochemical behavior of the ITO/Ag-ZnO NWs electrode/Na 2 SO 4 electrolyte solution interface. X-ray diffraction revealed that the all samples are mainly crystallized in wurtzite ZnO phase. The scanning electron microscopy images show that in the absence or presence of Ag, nanowires appear uniform and stand perpendicular onto substrate with hexagonal shape implying the occurrence of the wurtzite ZnO crystal structure. The presence of Ag nanoparticles is clearly envisioned by EDX spectra. The obtained results According to optical measurements the band gap for undoped ZnO NWs is about 3.25 eV, close to that of ZnO (films, powder and nanorods) 3.36 eV. Optical absorption shows a surface Plasmon resonance effect at 400 nm and 550 nm. Microanalysis confirmed that the amount of Ag in thin solid films is proportional to the Ag content in the starting electrolyte. The increase of Ag-doping results in a decrease of the photoluminescence intensity and blue shift and has been assigned to the Plasmon effect of Ag. Photoelectrochemical measurements showed that the photocurrent increases from 0.05 mA for undoped ZnO NWs to 0.14 mA for the 3% Agdecorated ZnO NWs.

“…An increment of 5% in the maximum absorbance was observed in the case of ZnO/ZnS core/shell nanowires compared to ZnO nanowires 161 . A reduction of 20% in the transmittance was obtained in the case of ZnO (80%) nanowires respect to ZnO/ZnSe (60%) core/shell nanowires 162 . A high reduction in the band gap, from 3.34 to 1.7 eV, was reported when ZnO nanowires were compared with ZnO/Cu2O core/shell nanowires 163 .…”

Recent progress in the electrochemical deposition of ZnO nanowires: Synthesis approaches and applicationsIn the last decade, nanostructuration is a demanding research topic due to the observation of interesting properties and, in consequence, applications on these nanostructures. This review collects the synthesis and possible applications of ZnO nanowires grown by electrodeposition and electroless methods. Respect to the synthesis of ZnO nanowires, growth mechanism and parameters are analysed depending on the technique used, electrodeposition or electroless. The mechanism growth of the nanowires using templateless and hard-templates is analysed resulting in different architecture of the ZnO nanowires. Moreover, ZnO nanowires and hybrid materials based on ZnO are also considered. Depending on the architecture of ZnO nanowires, the properties and applications are different.This review also studies the properties and applications in which ZnO nanowires can be used and how these applications are different depending on the architecture of the nanostructure. This review gives a complete perspective referent to the synthesis, properties and application of ZnO nanowires grown by electrosynthesis techniques.
