Abstract The large open‐circuit voltage ( V OC ) losses limit the enhancement of power conversion efficiency (PCE) in printable mesoscopic perovskite solar cells (p‐MPSCs). These primarily result from high defect density at grain boundaries within mesoporous scaffold, which promotes non‐radiative recombination. In this study, crystallization improvement and modulation is promoted by adopting a multifunctional ionic liquid, 1‐butyl‐2,3‐dimethylimidazolium trifluoromethanesulfonate (BMMIm[OTF]). imidazolium ions BMMIm[OTF] form hydrogen bonds with PbI 6 4− framework coordinate under‐coordinated lead through S═O bonds. interactions synergistically improve crystallinity films optimize energy level alignment perovskite/carbon electrode interface. This improved interface facilitates more efficient charge transfer extraction while reducing As result, champion p‐MPSCs incorporating achieve PCE 20.02% 1.055 V, significantly outperforming control devices 0.965 V. Furthermore, hydrophobic nature enhances device stability. research provides practical strategy for developing durable p‐MPSCs.

Abstract Mesoporous electron transport layer (ETL) in printable mesoscopic perovskite solar cells (p‐MPSCs) enables rapid and selective extraction of photogenerated electrons facilitates device fabrication without a hole (HTL). However, the inherent mesoporous architecture introduces abundant interfacial defects that promote undesired non‐radiative recombination, limiting power conversion efficiency (PCE). To address this challenge, an interface field‐effect passivation strategy is implemented, leveraging spatially cation extrusion. By incorporating tetraphenylphosphonium cations, sterically bulky organic ions migrate to perovskite/ETL during crystallization, robust electrostatic field introduced. This simultaneously suppresses recombination by inducing enhances charge through optimizing energy alignment. The synergistic effects yield PCE enhancement from 19.4% 21.0%. work underscores potential cation‐engineered fields improve performance HTL‐free carbon‐electrode photovoltaics.
