The Front Cover shows the crystal structure of a Ruddlesden‐Popper quasi‐2D perovskite with chemical formula (PEA) 2 MA 39 Pb 40 I 121 (with PEA: phenylethylammonium and MA: methylammonium). The subscript 40 indicates the number of PbI6 octahedra separated by a double layer of PEA cations. Such quasi‐2D perovskites exhibit efficient photovoltaic performances and higher stability with respect to the pure 3D counterpart (MAPbI 3 ). More information can be found in the Communicaton by G. Grancini, M. K. Nazeeruddin, and co‐workers.
