Although ${\alpha}$-Fe$_2$O$_3$ has been investigated extensively in photoelectrochemical (PEC) systems, however, producing efficient and practical photoelectrodes remains a challenge. Here, we demonstrate the ${\alpha}$-Fe$_2$O$_3$ photoanodes fabricated by employing two different organic solvents (ethanol and methanol) via aerosol-assisted chemical vapour deposition. The idea is to show that using different solvents could influence the overall performance of the fabricated photoanode. It is observed that the solvent with higher polarity enhanced the crystal growth direction of ${\alpha}$-Fe$_2$O$_3$ on the (110) orientation of the rhombohedral structure and the solution with lower polarity resulted in superior grain growth. The light absorption improved with the energy bandgap reduced significantly due to the enhancement of morphological formation. The PEC performance exhibited good photoanodic responses with photocurrent density increased graduallyfrom 29 to 75 ${\mu}$A cm$^{–2}$ at 1.23 V (
vs . RHE), resulting in good charge transfer behaviour and stability. This provides valuable information on the possible strategy in producing efficient optoelectronic devices.
