BiVO4 Photoanode with Exposed (040) Facets for Enhanced Photoelectrochemical Performance
Nano-Micro Letters, 2017 A BiVO4 photoanode with exposed (040) facets was prepared to enhance its photoelectrochemical performance. The exposure of the (040) crystal planes of the BiVO4 film was induced by adding NaCl to the precursor solution.

ZnO Hierarchical Nanostructure Photoanode in a CdS Quantum Dot-Sensitized Solar Cell. [PDF]
PLoS ONE, 2015 A hierarchical array of ZnO nanocones covered with ZnO nanospikes was hydrothermally fabricated and employed as the photoanode in a CdS quantum dot-sensitized solar cell (QDSSC). This QDSSC outperformed the QDSSC based on a simple ZnO nanocone photoanode

Ultrathin Hematite Photoanode with Gradient Ti Doping [PDF]
Research, 2020 The poor photoelectrochemical (PEC) performance derived from insufficient charge separation in hematite photoanode crucially limits its application. Gradient doping with band bending in a large region is then considered as a promising strategy, facilitating the charge transfer ability due to the built-in electric field.

An n-Si/n-Fe2O3 Heterojunction Tandem Photoanode for Solar Water Splitting [PDF]
CHIMIA, 2013 Few metal oxide photoanodes are able to reduce protons to hydrogen because their conduction band minimum is located at too positive potentials. This can be remedied by biasing the photoanode with a photovoltaic cell placed behind the photoanode.

Photocorrosion of WO3 Photoanodes in Different Electrolytes [PDF]
ACS Physical Chemistry Au, 2021 Photocorrosion of an n-type semiconductor is anticipated to be unfavorable if its decomposition potential is situated below its valence band-edge position. Tungsten trioxide (WO3) is generally considered as a stable photoanode for different photoelectrochemical (PEC) applications.
