“…The first advantages were connected with antireflectance properties of an NRs array. In 2012 a paper was published on the growth of ZnO NRs on a ZnO/textured c-Si photovoltaic device through the hydrothermal method [80]. The reflectance spectra and I-V characteristics indicated that the ZnO/textured c-Si photovoltaic device with ZnO NRs had the lowest reflectance among the tested devices, especially in the range of UV and green light (350 nm to 590 nm).…”

This paper contains a review describing the various potential applications of ZnO nanorods in many different devices such as light emitters (light emitting diodes and lasers) and detectors (on single nanorod or nanorods matrices), photovoltaic cells (dye-sensitized, perovskite-based, thin film, organic and silicon solar cells), photocatalytic applications, field emitters, field effect transistors, chemical and biological sensors, and electric nanogenerators. The review describes state of art in this field from more than twenty years perspective, presenting problems and challenges to be solved.

“…Nanostructures (NSs) in a semiconductor reduce the refraction ratio of incident light due to light scattering and trapping and thus increase the absorption efficiency . ZnO nanowires (NWs) show excellent UV absorption efficiency, but their surface exhibits oxygen absorption and desorption under UV irradiation, leading to a slow response and recovery. , The surface of ZnO NWs has been covered with a sheet layer of NiO, which isolates the oxygen, and thus speeds up the response and recovery.…”

Chemical solutions consisting of NiO/ZnO p–n heterojunction nanowires (NWs) decorated with Pd nanoparticles on a glass substrate were used to fabricate an ultraviolet (UV)/visible photodetector. The photodetector was composed of ZnO hexagonal wurtzite and NiO cubic crystalline structures. A few NiO nanograins were found to epitaxially grow on the ZnO NW surface. The current–voltage curve for the photodetector exhibited rectification in the dark and under green and blue light-emitting diode (LED) illumination, whereas an approximately linear current–voltage curve was found under UV LED illumination. The I green/I dark, I blue/I dark, and I UV/I dark ratios for the photodetector were 91.4, 403.2, and 1.25 × 105, respectively. Multilayer structures of the photodetector are sensitive toward the UV and visible bands.

“…Studies have found that zinc oxide (ZnO) is a promising material for application in a variety of devices because it is a chemically and thermally stable n‐type semiconductor with a large exciton binding energy (60 meV) and a large band gap energy (3.37 eV) at room temperature . Compared with planar thin film devices, nanostructure devices are expected to have a larger response to light, especially from ultraviolet (UV) to green light in the solar spectrum , which can increase the light absorption of the top cell for short wavelengths.…”

ZnO nanowire (NW) grown on triple-junction (TJ) solar cells via the hydrothermal growth method to enhance efficiency is investigated. In this paper, experimental results indicate that TJ solar cells with ZnO NW as an antireflection (AR) coating have the lowest reflectance in the short wavelength spectrum, as compared with those of bare TJ solar cells (without AR coating) and solar cells with SiN x and TiO 2 /Al 2 O 3 AR coatings. ZnO NW has the lowest light reflection among all experimental samples, especially in the range of ultraviolet to green light (300-500 nm). It was found that ZnO NW could enhance the conversion efficiency by 6.92%, as compared with the conventional TJ solar cell. In contrast, SiN x and TiO 2 /Al 2 O 3 AR coatings could only enhance the conversion efficiency by 3.72% and 6.46% increase, respectively. The encapsulated results also suggested that the cell with ZnO NW coating could provide the best solar cell performances. Furthermore, all samples are measured at tilt angles of 0 -90 and results show that the solar cells with ZnO NW have the highest efficiency at all tilt angles. Furthermore, a small NW diameter increases light absorption.
