摘要：

Two-dimensional (2D) Dion-Jacobson (DJ) perovskite solar cells (PVSCs) with high PCE are currently predominately fabricated via a hot-casting process. While it is difficult to prepare high-quality perovskite film under mild conditions when the application of divalent ammonium. In this work, the morphology of the 2D DJ perovskite film was tuned with the aid of MASCN additive under room temperature spin-coating deposition conditions. The device with inverted planar structure presented a hero performance of JSC of 17.91 mA cm(-2), Voc of 1.19 V, FF of 0.76 and PCE of 16.25%, which is the highest PCE ever reported for hot-casting free 2D DJ PVSCs.
