The Back Cover shows a three‐layer membrane used to house a solar‐driven water splitting system consisting of rod‐shaped semiconductor absorbers. The central layer, consisting of semi‐reduced graphene oxide, conducts charge for efficient and wireless connection and catalyzes water dissociation. It is sandwiched between two ion‐exchange layers that are selective towards either protons or hydroxide. This membrane system, therefore, allows oxidation and reduction to occur under basic and acidic conditions (i.e., in a steady‐state pH gradient) and can thus stabilize inexpensive and earth‐abundant conversion materials used for the widespread generation of solar fuels. More details can be found in the Full Paper by McDonald et al. on page 2645 in Issue 16, 2015 . (DOI: 10.1002/cssc.201500538 ).
