“…ZnO should attain higher efficiency to be used in DSSCs. In this regard, the DSSCs contained nanostructural zinc oxide showed significantly improved efficiency in comparison to thin films of zinc oxide because of the large surface area, improved light collecting, and abilities to light scattering [82]. A schematic overview of a usual DSSC is presented in Fig 3 . 1D nanostructure ZnO composites with different morphologies, such as nanorods, nanotubes, nanowires, and nanofibers, have been widely investigated to be applied in DSSC, and extensive studies have been performed about it in the literature compared to the other morphologies.…”

Zinc oxide (ZnO) is used for various purposes because of its special physico-chemical properties, including large band gap, high binding energy of exciton, nontoxicity, high chemical and thermal stability, large piezoelectric constants, and wurtzite crystal structure with various and widespread applications in electronics, optoelectronics, biochemical sensing, biomedical, and energy-saving systems. This review mainly aimed to present the recent improvement in ZnO-based composite materials with utilization in energy storage systems with a specific focus on lithium-ion batteries, dye-sensitized solar cells, and supercapacitors. The first part of this paper looks at the structure and properties of ZnO and then describes some of the most common synthesizing methods of ZnO composites, including electrochemical, chemical, solvo/hydrothermal, and physical deposition methods. Finally, the recent advancement of ZnO-based composite materials applied in energy storage systems was discussed.

“…Also, different morphologies such as nanoparticles, nanowires and nano owers in DSSCs afford improved light absorption and electron collecting e ciency in the devices [7,8]. Thus, this made extensive research work to focuss on the metal oxide nanocomposite photoanodes using TiO 2 , ZnO, SnO 2 etc., than individual metal oxide semiconductors (MOS) [9]. Among these MOS, zinc oxide (ZnO), tin oxide (SnO 2 ) and vanadium oxide (V 2 O 5 ) has been chosen in this present work to carry out studies on DSSC.…”

In this present work, zinc - tin - vanadium oxide (ZTVO) nanocomposite was prepared using hydrothermal route and was subjected to calcination at 600 0 C. The sample was systematically characterized by Powder X-ray Diffractometer (XRD), Attenuated Total Reflectance (ATR), Field Emission Scanning electron Microscope (FE-SEM), Transmission Electron Microscope (TEM) and Ultraviolet- Diffuse Reflectance Spectroscopic techniques. From the investigations, it is observed that this composite possess the combination of both individual and binary phases. The elongated nanostructures obtained due to the binary phases and spherical shaped nanostructures obtained due to the individual phase were observed from the FE-SEM image. The formation of the nanocomposite has further been confirmed from TEM and HRTEM images. ZTVO nanocomposite possess large surface area of 167.3 m2/g and pore size value around 11 nm. Also, the band gap of the material has been found to be 1.97 eV. Dye-sensitized solar cell (DSSC) has been fabricated using this ZTVO nanocomposite as the photoanode and betalain dye extracted from beetroot (Beta vulgaris) as the natural dye. This simple protocol was formulated at a low cost for the first time for DSSC fabrication and it has attained the efficiency of 3.41%. This better efficiency of ZTVO might be due to larger surface area, presence of pores in addition to smaller band gap.

Dye-sensitized Solar Cell (DSSC) based on ZnO nanostructures has been fabricated using mangosteen peel extract as dyes using the Yonekawa method and the Grätzel method. This research synthesized ZnO nanostructures with nanoparticles, nanorods, nanoflower, and nanotree morphologies. Two different morphological structures of ZnO were mixed with the ratio of 25:75, 50:50, and 75:25, and the performance of the DSSC was investigated. The dye used in the DSSC was extracted from mangosteen peel of different varieties obtained from Blitar, Purwakarta, and Gede Bage. The highest anthocyanin levels were obtained from the Gede Bage sample with a value of 105.774 mg L−1. The results of the I-V curve measurement showed that the most stable values of open-circuit voltage (Voc) and short circuit current (Isc) were obtained from the dye extracted from the Blitar sample with the value of 0.312 V and 3 μA respectively for the Yonekawa method (0.001 28 % efficiency) as well as 0.222 V and 5.5 μA respectively for the Grätzel method (0.00264 % efficiency). The best efficiency was obtained from the mixtures of nanoparticles (75) : nanotrees (25) with the value of 0.034 77 % (0.285 V Voc, 27.5 μA Isc, and FF 26.5 %) using the Yonekawa method.
