“…Meanwhile, the degradation of the MB dye increased by about 76% by increasing Ni incorporation. According to these results, it was confirmed that the presence of Ni ions at the ZnO site improves the photocatalytic properties of ZnO thin films due to the shift of the optical band gap energy to the visible wavelength [15].…”

We report the effect of Ni-doped ZnO thin films on the photodegradation of methylene blue (MB) under visible irradiation. The Ni-doped ZnO thin films were deposited on a silicon substrate by ultrasonic spray pyrolysis (USP) at 450 °C for 15 minutes. The ZnO thin films are characterized by X-ray diffraction (XRD) and UV-Vis spectroscopy. The X-ray diffraction (XRD) pattern for all samples confirms that the crystalline phase of Ni-doped ZnO thin films is polycrystalline hexagonal wurtzite. However, due to the Ni incorporation into the ZnO site, there is a change in the crystal plane. All ZnO films confirmed photocatalytic properties, indicating methylene blue (MB) degradation under visible irradiation. Nevertheless, the degradation of the MB dye increased by about 76% with increasing Ni incorporation. Therefore, we confirmed that Ni incorporation affects the photocatalytic properties of the ZnO thin films.

“…Table 2 lists the photovoltaic performance parameters of the DSSCs with different photoanode structures. It is obvious in Table 2 that the photoanode with the structure of ZnO nanorods decorated TiO 2 thin film is more efficient than those with the structures of TiO 2 -ZnO core-shell nanograss [18], TiO 2 -decorated ZnO nanorod [19], and composite ZnO/TiO 2 (90/10) [20], although less efficient than the …”

By increasing the temperature of hydrothermal reactions from 70 to 100 ∘ C, vertically aligned ZnO nanorods were grown on the TiO 2 thin film in the photoanode of dye-sensitized solar cells (DSSCs) as the blocking layer to reduce the electron back recombinations at the TiO 2 /electrolyte interfaces. The length effects of ZnO nanorods on the photovoltaic performances of TiO 2 based DSSCs were investigated by means of scanning electron microscope, X-ray diffractometer, photoluminescence spectrophotometer, and the photocurrent-voltage measurement. Under the illumination of 100 mW/cm 2 , the power conversion efficiency of DSSC with ZnO nanorods decorated TiO 2 thin film as its photoanode can be increased nearly fourfold from 0.27% to 1.30% as the length of ZnO nanorods increases from 300 to 1600 nm. The enhanced efficiency of DSSC with ZnO nanorods decorated TiO 2 thin film as the photoanode can be attributed to the larger surface area and the lower defect density in longer ZnO nanorods, which are in favor of more dye adsorption and more efficient transport in the photoanode.
