Abstract

<jats:title>Abstract</jats:title><jats:p>The optical and photoelectrochemical (PEC) properties of semiconductors can be manipulated by varying the deposition time and the solvent used. In this work, the study investigates the influence of organic solvent (methanol and ethanol) on accelerating deposition time for the efficient optical and photoelectrochemical performance of the fabricated α-Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> thin film photoanode below 10 minutes. The α-Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> film was fabricated via aerosol-assisted chemical vapor deposition (AACVD). The study discovered that the solvent with high polarity enhanced the crystal growth direction of <jats:italic>α</jats:italic>-Fe2O3 on the (110) orientation. The UV-vis showed that all deposited <jats:italic>α</jats:italic>-Fe2O3 films exhibit the absorption band in the visible-light region with the estimated energy bandgap of 2.10 eV. Furthermore, the PEC performance exhibited good photoanodic responses with excellent charge transfer behavior and photostability. These findings show that the choice of solvent could influence the rapid deposition time, thus, would be reliable to accelerate the fabrication process of photoelectrochemical water-splitting photoanode.</jats:p>
