Flexible perovskite solar cells (f-PSCs) have emerged as potential candidates for specific mechanical applications owing to their high foldability, efficiency, and portability. However, the power conversion efficiency (PCE) of f-PSC remains limited by inferior contact between flexible buried substrate. Here, an asymmetric π-extended self-assembled monolayer (SAM) (4-(9H-dibenzo[a,c]carbazol-9-yl)butyl)phosphonic acid (A-4PADCB) is reported a substrate efficient inverted f-PSCs. Employing this design strategy, A-4PADCB exhibits significant orientation angle away from surface normal, homogenizing distribution potentials. This enhancement improves SAM/perovskite interface quality, controlling growth favorable films with low defect density slight tensile stress.

Abstract Organic self‐assembled molecules (OSAMs) based hole‐transporting materials play a pivotal role in achieving highly efficient and stable inverted perovskite solar cells (IPSCs). However, the reported carbazol‐based OSAMs have serious drawbacks, such as poor wettability for solution spreading due to nonpolar surface, worse matched energy arrangement with perovskite, limited molecular species, which greatly limit device performance. To address above problems, novel OSAM [4‐(3,6‐glycol monomethyl ether‐9H‐carbazol‐9‐yl) butyl]phosphonic acid (GM‐4PACz) was synthesized material by introducing glycol ether (GM) side chains at carbazolyl unit.
