Abstract Perovskite solar cells (PSCs) have garnered significant attention for their outstanding optoelectronic properties, yet surface defects remain a major obstacle to achieving optimal performance, especially in scalable hybrid evaporation‐solution fabrication methods. Conventional passivation techniques often struggle with shallow penetration of agents, limiting effectiveness. Here, an advanced post‐treatment strategy is introduced that synergistically combines 2‐thiopheneethylammonium chloride trace amount ethylenediamine achieve superior passivation. acts as “penetration facilitator,” mildly etching the perovskite and enabling deeper infiltration chloride, which results formation uniformly distributed pure‐phase 2D layer. This deeply penetrating layer effectively suppresses nonradiative recombination at perovskite/electron transport interface. As result, inverted PSCs fabricated using method achieved power conversion efficiency 24.20%, accompanied by open‐circuit voltage 1.189 V deficit 0.36 V. Additionally, this demonstrates broad performance enhancements across various bandgaps methods, offering versatile promising pathway boost both stability PSCs.

Abstract Although p‐i‐n type inverted perovskite solar cells (PSCs) achieve excellent photoelectric efficiencies, the nonradiative recombination at perovskite/C 60 interface is still key factor affecting overall efficiency of PSCs. Herein, a synergistic passivation strategy (meta‐fluoro‐phenylethylammonium iodide and piperazine iodide) developed to modify in This facilitates situ reconstruction film obtain smooth flat surface. Furthermore, two molecules work synergistically passivate surface defects, adjust energy levels, bolster electric field, all which reduce losses interface.

The typical anisotropic crystal orientation in Ruddlesden–Popper perovskites (RPPs) is not conducive to carrier transport, resulting a reduced power conversion efficiency (PCE) compared three‐dimensional perovskites. Here, we present novel method for manipulating the by introducing self‐assembled molecular layer, MeO‐2PACz ([2‐(3,6‐dimethoxy‐9H‐carbazol‐9‐yl)ethyl] phosphonic acid), as an interlayer between PTAA (poly[bis(4‐phenyl)(2,4, 6‐trimethylphenyl) amine]) and perovskite. phosphate group of bonds with Pb 2+ RPP, promoting vertical formation perovskite facilitating efficient charge transport within RPP materials. Additionally, grain size increased, boundary defects are passivated, which contributes suppressed nonradiative recombination carriers. incorporation significantly improves PCE optimized device 17.80%, without MeO‐2PACz, has approximately 15.68%. This presents highest MA‐based RP solar cell (PSC) utilizing 4FPEA (4‐fluoro‐phenethylammonium) spacer cation. Furthermore, unencapsulated devices demonstrate superior thermal stability. proposed optimization offers new insights into manipulation growth orientation.

The limited operational stability of perovskite solar cells (PSCs) remains the primary obstacle to their commercialization. Introducing organic molecules with coordination and hydrogen bonding has been demonstrated as an effective strategy for enhancing PSCs. Herein, we introduced acrylamides into precursor solution, enabling in situ polymerization form polyacrylamide at grain boundaries without sacrificing crystal quality films. -C = O -NH2 functional groups bonds uncoordinated Pb2+ I- boundaries, respectively. nonradiative recombination obviously suppressed, efficiency improved from 24.55to 25.85%.
