Abstract

Abstract : In article number1803699, Ulrich W. Paetzold and co‐workers develop a novel 2D Ruddlesden–Popper perovskite interlayer by solution processing n‐butylammonium bromide on wide‐bandgap double‐cation perovskite absorber layers (EG ≈ 1.72 eV). The devices with this 2D/3D heterostructure induce a high open‐circuit voltage of up to 1.31 V, which leads to very high stable power output efficiencies of up to 19.4% for wide bandgap perovskite solar cells.
