Abstract

This work reports the development of a photoelectrode composed of a copper-foam-supported Cu₂O@NiMn₂O₃ (CF@Cu₂O@NiMn₂O₃) heterostructure with a porous texture that can enhance supercapacitor performance through effective photo-responsive behaviour. Across a range of current densities, the photo-induced capacitance increased from 8.22% to 19.8%, delivering a maximum areal capacitance of 3032.5 mF cm⁻². The device exhibited exceptional stability in cycle testing, with a capacitance retention of 111.1% and coulombic efficiency retention of 100%.
