In article number 1900194 , Jooho Moon and co‐workers report a novel method for boosting visible‐light harvesting in the CuFeO 2 photocathode. The introduction of an inverse opal structure allows for exceptional near‐bandgap photon harvesting owing to the multiple scattering together with the short diffusion distance. The CuFeO 2 ‐based photocathode exhibits a record‐breaking photocurrent density for water reduction among p‐type ternary oxide‐based photocathodes.
