The incorporation of bulky organic cations into metal-halide perovskites, forming 2D–3D heterojunctions, has dramatically improved the stability of perovskite solar cells (PSCs). Nevertheless, the power conversion efficiencies (PCEs) of these PSCs are typically sacrificed because the formed 2D struc...
