Abstract The interface modification between perovskite and electron transport layer (ETL) plays a crucial role in achieving high performance inverted photovoltaics (i‐PPVs). Herein, non‐fullerene acceptors (NFAs), known as Y6‐BO Y7‐BO, were utilized to modify the perovskite/ETL i‐PPVs. Non‐polar solvent‐soluble NFAs can effectively passivate surface defects without structural damage of underlying films. Additionally, improved phenyl‐C61‐butyric acid methyl ester (PCBM) ETL induced by significantly accelerates electrons extraction. As result, both Y7‐BO exhibit more effective effects compared traditional PI molecules. power conversion efficiency (PCE) solar cell (i‐PSC) modified with reaches 25.82 %. Moreover, adoption non‐polar solvents superior semiconductor properties molecules also enable modules (i‐PSM) areas 50 cm 2 , 400 1160 achieve record efficiencies 23.05 %, 22.32 21.1 % (certified PCE), respectively, making them best PCE reported literature.

Molecular materials with high structure-design freedom are used as new interface passivators to reduce nonradiative recombination in inverted perovskite solar cells (PSCs). However, most molecular modifiers unable achieve a long-term passivation effect due self-aggregation. Here, the modifier 1-methyl-2-thiomethyl-1H-imidazole-5-carboxylate (SMC) ester and thiol groups is carefully developed. The weaken self-aggregation triggered by intermolecular hydrogen bonds, making such aggregations easier disassemble during heating form net-like insulating layer random openings, which dramatically increase charge transport. More importantly, electron transfer between disulfide can accelerate elimination of Pb0 I2 redox reactions prevent phase separation. Ultimately, optimized PSCs bandgaps 1.68 1.55 eV showed surprising fill factors 84.83% 86.18%, resulting champion efficiencies 23.45% (certified 22.98%, highest date for wide-bandgap) 25.71% 25.28%), respectively. Remarkably, both unencapsulated devices maintained over 94% their initial efficiency under maximum power point tracking 600 h (50 °C) 1000 (65 °C), respectively, confirming impressive operational stability.

Abstract The integration of organic dyes in perovskite solar cells (PSCs) to utilize near‐infrared (NIR) photons remains a challenge. In this study, selenium‐incorporated ortho‐benzodipyrrole‐based NIR dye CB‐2Se was developed. CB‐2Se, featuring lower bandgap 1.35 eV, blended with PCBM form bulk‐heterojunction layer PSCs for electron extraction and transport. Compared Y6‐16 acceptor, the removal Tz unit suppresses self‐aggregation, improving its compatibility PCBM. A CB‐2Se:PCBM‐incorporated PSC achieved remarkable power conversion efficiency (PCE) 25.18% V OC 1.164 V, J SC 25.71 mA/cm 2 , Fill Factor 84.15%, outperforming that PCBM‐only reference device (24.35%) PCBM:Y6‐16‐based (24.49%). PCBM:CB‐2Se enhanced long‐term stability PSCs, retaining 88% initial after 1000 h under ambient air thermal conditions. photophysical interactions between have been comprehensively investigated by using femtosecond transient absorption spectroscopy. Ultrafast exciton separation into free charges occurs within 200 femtoseconds at interfaces CB‐2Se. For first time, transfer holes from back detected, providing valuable insights charge dynamics utilizing dyes.

Abstract Despite the promise of self‐assembled organic hole‐transport layers (HTLs) in inverted perovskite solar cells, critical concerns persist about their structural stability under external fields such as bias and illumination, which have been regarded a potential threat to device's longevity. To address this issue, instead using molecules, intrinsically stable p‐type, wide bandgap CuCrO 2 colloidal nanocrystals with high monodispersity are synthesized them into HTL via simple dip‐coating method. By further HCl‐mediated ligands exchange, ‐HTL creates thermally chlorinated surface that can not only enhance electronic coupling inter but also provide contact passivation on defects. These merits eventually endow constructed buried interface favorable contact, thus facilitating efficient hole transfer. Consequently, an impressive power conversion efficiency 25.35% is achieved, accompanied by greatly improved longevity different accelerated‐aging tests.

Abstract Semi‐transparent perovskite solar cells (STPSCs) have shown great potential in Building Integrated Photovoltaics (BIPVs). Inverted STPSCs with nickel oxide (NiO x ) hole transport layer are preferred for BIPVs due to their excellent stability and transparency. However, performance is limited poor NiO /perovskite interface leading non‐radiative recombination degradation. Here, the study uses different fluorinated benzoic acids viz. 4‐fluorobenzoic acid, 3,4‐di‐fluorobenzoic 3,4,5‐tri‐fluorobenzoic improve effect of fluorine substitution on acid. Chemical interaction between these molecules can remove hydroxyl groups from surface, mitigating defect states which results reduced recombination. modified acid demonstrate a champion power conversion efficiency (PCE) 15.12% an average visible transmittance (AVT) ≈30%. Modified unencapsulated device maintains 90% its initial PCE after 1500 hours, stored 30–35% humidity, demonstrating superior stability. This emphasizes role buried interfacial passivation development building facades, windows, or skylights.
