Constructing low-dimensional/three-dimensional (LD/3D) perovskite solar cells can improve efficiency and stability.

Abstract [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl]phosphonic acid (Me‐4PACz) consistently exhibits inhomogeneous distribution on the substrate, which makes it a challenge for growth of high‐quality perovskite film, resulting in undesired interfacial losses at buried interfaces. Moreover, flexible alkyl chains Me‐4PACz are not conducive to intermolecular interactions and hinder charge flow.
