Enhanced photoelectrochemical water splitting efficiency: Increasing the photo anode’s properties by doping on the fluorine doped tin oxide glass surface

Аннотация

The recent accomplishments in using Sn or Ge, Mn and Ti-doped hematite photoanodes for solar water splitting are highlighted in this paper. Magnetron sputtering and hydrothermal methods were applied for depositing the alloyed films on Fluorine doped Tin Oxide (FTO) glasses. Results were compered by structural and morphology analysis using scanning electronic microscopy (SEM) images and XRD. Similarly, a comparison was done by using optical properties and photocatalytic activities. Doping elements for all samples illustrated higher photocurrent density to compare un-doped hematite. This research confirms that doped elements enhance the charge carriers and reduce the recombination losses, and it emphasizes that these treatment results in better photoelectrochemistry performance of Fe₂O₃ nanostructured photoanodes.
