Abstract

The design of photoelectrochemical (PEC) cell structures that mitigate challenges related to mass transfer is the key to achieving efficient hydrogen production. A PEC cell based on an integrated photoelectrode incorporating (ZnSe)_0.85(CuIn_0.7Ga_0.3Se₂)_0.15 strips and BiVO₄ strips exhibited 1.0% solar-to-hydrogen energy conversion efficiency even without stirring the electrolyte solution.
