The Cover picture shows the scale up of photoelectrodes for photoelectrochemical water splitting from lab size over demonstrator size to a full‐size panel with a network of busbars. To move further towards practical implementation in solar hydrogen production, it is mandatory to propose scalable energy‐ and cost‐saving fabrication processes. One promising design principle are particle‐based photoelectrodes. These electrodes are versatilely made of photocatalytically active semiconductor particles, in this case LaTiO 2 N, immobilized on a conducting substrate and linked by conducting connectors. Scale up from lab size (1 cm 2 ) to demonstrator size (40 cm 2 ) is shown. The observed scale up‐related performance losses might be mitigated by the incorporation of a tight network of bias contact points similar to busbars.
