“…In Table 1, even though it was observed that the film made with ZnO has the highest performance, ZnO/NiO composite nanoparticles can provide large surface areas for the dye adsorption. The photovoltaic performances of obtained DSSCs employing ZnO nanoparticles are comparable to published literature [29,30]. In addition, the sc and the cell efficiency of the solar cell constructed using NiO are in good agreement with the literature [31,32].…”

The mixture of ZnO and NiO effect on solar cell has been investigated. ZnO and NiO particles were produced by hydrothermal method and the produced particles were annealed at 500°C for 1 hour. Crystal structure and morphological properties of particles were examined by X-ray diffraction (XRD) and scanning electron microscope (SEM). XRD measurements showed that ZnO particles have a hexagonal wurtzite structure and NiO particles have a cubic structure. SEM results show that both ZnO and NiO particles are the form of nanoparticles. Dye-sensitized solar cells were fabricated by N-719 (Ruthenium) dyes and mixing ZnO/NiO particles in different ratios, 100/0, 50/50, and 0/100. It was observed that the solar cells made with ZnO have the highest performance with the efficiency of 0.542%. In addition, it was observed that when amount of NiO ratio increases in the mixture of ZnO/NiO, the efficiencies of DSSCs were observed to decrease.

“…As revealed in the figures, the photovoltaic performances of our DSSCs employing ZnO NRs are comparable to published literature [22,23,24]. A higher amount of dye was adsorbed on longer NRs than on shorter NRs, indicating that longer NRs improve photon absorption and carrier generation.…”

In this study, aligned zinc oxide (ZnO) nanorods (NRs) with various lengths (1.5–5 µm) were deposited on ZnO:Al (AZO)-coated glass substrates by using a solution phase deposition method; these NRs were prepared for application as working electrodes to increase the photovoltaic conversion efficiency of solar cells. The results were observed in detail by using X-ray diffraction, field-emission scanning electron microscopy, UV-visible spectrophotometry, electrochemical impedance spectroscopy, incident photo-to-current conversion efficiency, and solar simulation. The results indicated that when the lengths of the ZnO NRs increased, the adsorption of D-719 dyes through the ZnO NRs increased along with enhancing the short-circuit photocurrent and open-circuit voltage of the cell. An optimal power conversion efficiency of 0.64% was obtained in a dye-sensitized solar cell (DSSC) containing the ZnO NR with a length of 5 µm. The objective of this study was to facilitate the development of a ZnO-based DSSC.

ZnO photoanodes for dye sensitized solar cell were sythesized by using sol-gel spin coating method. XRD pattern confirmed that ZnO film was crystalline in nature and crystallite size calculated was 45.8 nm. The grain size measured form SEM image of ZnO film was 66.6 nm. Transmission of thin film was observed 75-92% in wavelength range from 400-800nm. The photon to electron conversion effieciency for dye loaded 6 and 12 hours time were obtained 0.38% and 0.44% respectively. In case of electrolytes ratio, the maximum effieciency and fill factor of DSSCs were found 0.44% and 0.49 respectively.
