Two layers are better than one : The organic bilayer composed of 3,4,9,10‐perylenetetracarboxylic acid bisbenzimidazole (PTCBI, an n‐type semiconductor) and cobalt phthalocyanine (CoPc, a p‐type semiconductor) was found to act as a novel photoanode that is responsive to visible light under 750 nm to induce efficiently the photoelectrochemical splitting of water to evolve dioxygen.
