A bilayered TiO2/CuO photoelectrode was fabricated on a fluorine-doped tin oxide FTO substrate by spin-coating and pulsed laser deposition methods. The prepared bilayered system was assessed as a photoelectrode for solar water splitting. The fabricated TiO2/CuO photoelectrode exhibited a higher photocurrent density (0.022[Formula: see text]mA/cm2 at 1.23[Formula: see text]V vs. RHE) compared to bare TiO2 photoelectrode (0.013[Formula: see text]mA/cm2 at 1.23[Formula: see text]V vs. RHE). This photocurrent density enhancement was attributed to the improved charge separation combined with the improved sunlight harvesting efficiency of a bilayered structure.
