Low field magneto-tunable photocurrent in CoFe₂O₄ nanostructure films for enhanced photoelectrochemical properties.

ABSTRACT: Efficient solar to hydrogen conversion using photoelectrochemical (PEC) process requires semiconducting photoelectrodes with advanced functionalities, while exhibiting high optical absorption and charge transport properties. Herein, we demonstrate magneto-tunable photocurrent in CoFe₂O₄ nanostructure film under low applied magnetic fields for efficient PEC properties. Photocurrent is enhanced from ~1.55 mA/cm² to ~3.47 mA/cm² upon the application of external magnetic field of 600 Oe leading to ~123% enhancement. This enhancement in the photocurrent is attributed to the reduction of optical bandgap and increase in the depletion width at CoFe₂O₄/electrolyte interface resulting in an enhanced generation and separation of the ph
