The Back Cover picture shows a solution‐processed thin film of semi‐conducting CuFeO 2 held in front of the sun. An impressive performance is reported using this material as a photocathode for the reduction of water molecules to hydrogen (as depicted in the bottom right corner) under solar radiation. In addition to being fully solution processable, the copper‐based delafossite (crystal structure is shown in the top right corner) is a class of material known for being stable in aqueous environments. Moreover, it is only composed of earth‐abundant materials, as suggested by the delafossite ore shown in the bottom right corner. Overall, these properties make p‐type CuFeO 2 a very attractive material in the quest for inexpensive, sustainable, and stable direct solar water splitting for the generation of carbon‐free hydrogen.
