A plasmonic black absorber is developed by X. Zhang and co‐workers in article number 1600399 by sandwiching a 150‐nm TiO 2 layer between a layer of random Au nanoparticles and a rough Au surface (200 nm thick). The combined plasmonic effect of the Au nanoparticles and the Au rough surface enables a strong absorption (72%–91%) over 400–900 nm and enhances the photocurrent by 20 fold.
