TLDR
Direct water electrolysis was achieved with a novel, integrated, monolithic photoelectrochemical-photovoltaic design that splits water directly upon illumination; light is the only energy input.Abstract:
Direct water electrolysis was achieved with a novel, integrated, monolithic photoelectrochemical-photovoltaic design. This photoelectrochemical cell, which is voltage biased with an integrated photovoltaic device, 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.read more
