1 Introduction The emergence of organometal halide perovskite solar cells (PSCs) has defined a new era of ultra-cheap solar cell research, and achieved a certified power conversion efficiency (PCE) of 26.1% to date in single-junction devices.[1] The current design of state-of-the-art PSCs is fabricated with a 3D perovskite/2D perovskite stacking structure, in which the 2D perovskite capping layer can passivate trap defects at grain boundaries (GBs) of the 3D perovskite and form favorable band...
