dc.description.abstract | In this study, the photoelectrochemical performance of Cu2O-based photoanodes is evaluated in terms of photoactivity and stability. The electrodes are based on the p-n junction consisting of Cu2O/Ga2O3, on which an Au layer is deposited, followed by the formation of Ni-based co-catalysts. The Au layer increases the light absorption in the entire wavelength range from 300 to 800 nm and leads to upward band bending at the Cu2O/Au interface; thus, more photogenerated hole charges are transported to the electrolytes. The electrodeposited FeNiOx thin layer significantly decreases the overpotential and increases the photoactivity; thus, the photoelectrochemical cell consisting of the Cu2O-based photoanode and platinum yields a photocurrent density of about 5.15 mA cm(-2) at 1.23 V vs. RHE with a small dark current density of 16 mu A cm(-2). | - |
