Abstract

Crystallographic orientation control is an effective method to improve the photoelectrochemical water splitting efficiency of BiVO₄ photoanodes. Herein, textured and transparent Mo-BiVO₄ photoanodes are fabricated by spin-coating Mo-doped BiVO₄ nanoparticles on FTO. The photoelectrodes exhibit a current density of 4.15 mA cm^-2 and 2.50 mA cm^-2 for sulfite and water oxidation, respectively. By connecting the photoelectrode with a CsPbBrI₂ perovskite solar cell, a stand-alone tandem water splitting device with a current density of 2.13 mA cm^-2 and an STH of 2.43% can be achieved.
