Abstract
Direct water electrolysis was achieved with a novel, integrated, monol ithic photoelectrochemical-photovoltaic design. This photoelectrochemi cal cell, which is voltage biased with an integrated photovoltaic devi ce, splits water directly upon illumination; light is the only energy input. The hydrogen production efficiency of this system, based on the short-circuit current and the lower heating value of hydrogen, is 12. 4 percent.
