“…They found that the surface morphological of the film was a plate-like structure. However, most of those reported works utilized a threeelectrode system, including working, counter, and reference electrodes for coating the films [17][18][19] . This a three-electrode system has several disadvantages such as more complicated set-up and maintenance.…”

ZnO material possesses a huge potential to be utilized as the photoanode in Dye Sensitized Solar Cells (DSSC) application. In this work, we prepared ZnO thin films with different zinc concentrations by a simple and low-cost electroplating technique. XRD analysis reveals that all ZnO thin films with different zinc concentrations have a hexagonal wurtzite crystal structure with crystallite sizes ranging from 19.37 to 32.96 nm. The SEM analysis demonstrated that particle size of the ZnO thin films increased from 46 ±12 to 78±28 nm as the zinc concentration increased from 0.1 to 0.4M. The optical properties analysis revealed the transmittance value of the ZnO thin film for all coating solution concentrations greater than 80%. The band gap energy of the ZnO thin films slightly decrease from 3.20 to 3.16 eV with increasing zinc concentrations from 0.1 to 0.4 M.

Either metal/metal or metal/non-metal co-doping is one of the most effective methods to modulate the visible emission of ZnO. In this paper, ZnO, aluminum-doped ZnO (Al-ZnO), aluminum and silver co-doped ZnO (Al/Ag-ZnO), and aluminum and nitrogen co-doped ZnO (Al/N-ZnO) are deposited. Combining the substitution of zinc ions using Al and/or Ag doping and the substitution of oxygen ions using N doping is expected to introduce more interstitial zinc and oxygen vacancy defects related to visible light emission in ZnO films. The results indicate that the PL spectrum of ZnO shows a violet emission peak at 406 nm and other weak visible emission peaks. After Al doping, we observe a strong blue emission at 421 nm, and its intensity is further enhanced and attains the maximum for Al/N-ZnO. However, for Al/Ag-ZnO, the blue emission shifts toward a longer wavelength, and the intensity of the blue emission conversely decreases. Then, the band structures, the density of states (DOS), the partial density of states (PDOS), and the optical constant of doped ZnO are calculated using density functional theory (DFT). Based on the experimental and theoretical results, the enhancement mechanism of visible light is discussed.
