In article number 1908492, Jungki Ryu, Byeong‐Su Kim, and co‐workers describe an approach to enhance the charge separation efficiency of water oxidation photoanodes by the interfacial dipole layer created by modifying their surface with polyelectrolyte multilayers assembled via a layer‐by‐layer technique. This approach is effective regardless of the pH and type of photoelectrodes, and potentially provides insights into the design and fabrication of efficient solar‐to‐chemical energy conversion devices.
