Abstract Self‐assembled monolayers (SAMs), particularly those molecules composed of carbazole and phosphonic acid, are widely employed as effective hole‐selective layer (HSL) in inverted perovskite solar cells (PSCs). However, the insufficient chemical bond formation with metal oxides (ITO) self‐aggregation solvents acid SAM led to non‐uniform HSL, which turn affect power conversion efficiency (PCE) stability PSCs. Herein, a series benzoic materials (BAs), including p‐fluorobenzoic (FBA) p‐methylbenzoic (MBA), used post‐assembly effectively fill voids between [4‐(3,6‐dimethyl‐9H‐carbazole‐9‐yl)butyl]phosphonic (Me‐4PACz) form denser facilitates passivation buried interface. In addition, post‐assembled BAs different dipole moments can adjust work function Me‐4PACz facilitating transport extraction charge carriers. Consequently, PSCs based on Me‐4PACz/FBA HSL realize champion PCE 25.58%. Moreover, unencapsulated devices maintain 82% 94% after 800 h outdoor storage (RH≈60%) 2000 glove box, respectively. This technique enhances both device, blazing simple pathway for further development

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. Here, novel molecule with 4‐Methoxy‐N‐(4‐methoxyphenyl)‐N‐phenylaniline (TPA) carbazole backbone, named CzTPA is designed, constituted Co‐SAM Me‐4PACz.

Abstract The performance of perovskite solar cells (PSCs) is often constrained by significant open‐circuit voltage ( V OC ) losses attributed to non‐radiative recombination processes induced detrimental trap states. Surface treatments using passivating ligands typically involve single active binding sites on perovskite, posing challenges for effective passivation.
