摘　　要：Photoelectrochemical(PEC)overall water splitting(OWS)represents a highly promising strategy to directly harvest solar energy and store it in the form of fuels,offering unique benefits such as mitigating issues connected to the intermittent nature of sunlight.The electrical voltage required for OWS may be,in principle,separated into different components:the thermodynamic driving force of generating oxygen and hydrogen at standard temperature and pressure(E^(0)_(cathode)−E^(0)_(anode)=−1.23 V),the overpotentials necessitated to surmount the kinetic barriers for the oxygen evolution reaction(OER)and hydrogen evolution reaction(HER)at practically meaningful current densities and the losses due to ohmic resistance within the cell.
