Abstract Synergistic morphology and defects management at the buried perovskite interface are challenging but crucial for further improvement of inverted solar cells (PerSCs). Herein, an amphoteric organic salt, 2‐(4‐fluorophenyl)ethylammonium‐4‐methyl benzenesulfonate (4FPEAPSA), is designed to optimize film energy level alignment interface. 4FPEAPSA treatment promotes growth a void‐free, coarse‐grained, hydrophobic by inducing crystal orientation. Besides, dual‐functional can chemically interact with film, passivate iodine formamidine vacancies, tending revert fermi its defect‐free state. Meanwhile, formation p‐type doping facilitate interfacial charge extraction transport PerSCs reduced carrier recombination loss. Consequently, improves efficiency devices 25.03% better storage, heat, humidity stability. This work contributes strengthening systematic understanding interface, providing synergetic approach realize precise control, effective defect suppression, efficient PerSCs.

Abstract Inverted perovskite solar cells (IPSCs) have attracted unprecedented attention due to their negligible hysteresis, long‐term operational stability, low temperature, and cost‐effective fabrication process, as well wide applications. The power conversion efficiency (PCE) of IPSCs has skyrocketed from 3.9% in 2013 certified 26.1% 2023, which is over the 25.8% regular counterpart, benefiting emergence a great number organic hole‐transporting materials (HTM). This review provides an overview recent development stability IPSCs, including small molecules conjugated conductive polymers. effective strategies for charge‐transport layer films are also discussed. Finally, prospective further outlined, developing novel fabricating techniques meet requirements commercial application.

Inverted perovskite solar cells based on weakly polarized hole-transporting layers suffer from the problem of polarity mismatch with precursor solution, resulting in a nonideal wetting surface. In addition to bottom-up growth polycrystalline halide perovskite, this will inevitably worse effects residual strain and heterogeneity at buried interface interfacial carrier transport localized compositional deficiency. Here, we propose multifunctional hybrid pre-embedding strategy improve substrate wettability address unfavorable heterogeneities. By exposing interface, it was found that films markedly reduced because presence organic polyelectrolyte imidazolium salt, which not only realized halogen compensation coordination Pb 2+ but also morphology defect recombination were well regulated. Benefitting above advantages, power conversion efficiency targeted inverted devices bandgap 1.62 eV 21.93% outstanding intrinsic stability. addition, coembedding can be extended 1.55 eV, champion device achieved 23.74%. optimized retained 91% their initial (960 h) when exposed an ambient relative humidity 20%, T80 680 h under heating aging 65 °C, exhibiting elevated durability.

Despite the fact that perovskite solar cells (PSCs) are widely popular due to their superb power conversion efficiency (PCE), further applications still restricted by low stability and high-density defects. Especially, weak binding ion–electron properties of crystals make them susceptible moisture attack under environmental stress. Herein, we report an overall sulfidation strategy via introduction 1-pentanethiol (PT) into film inhibit bulk defects stabilize Pb ions. It has been confirmed thiol groups in PT can uncoordinated ions passivate iodine vacancy forming strong Pb–S bonds, thus reducing nonradiative recombination. Moreover, favorable passivation process also optimizes energy-level arrangement, induces better crystallization, enhances charge extraction full cells. Consequently, PT-modified inverted device delivers a champion PCE 22.46%, which is superior control (20.21%). More importantly, retains 91.5% its initial after storage air for 1600 h over 85% heating at 85 °C 800 h. This work provides new perspective simultaneously improve performance PSCs satisfy commercial applications.

Perovskite solar cells (PSCs) have gained tremendous research interest recently owing to several advantages, including low material cost, facile solution processability, bandgap tunability, and alluring device efficiency. The organic formamidinium (FA) cation‐based perovskites are mainly considered as one of the potential candidates for charge carrier generation due their excellent properties, such thermal stability than traditional perovskites. However, inevitable unfavorable polymorphism (i.e., α δ ) at room temperature still forms basis numerous works allow fabrication a high‐quality absorber enhances PSCs performance. studies resolve contemporary techniques (e.g., passivation strategy) with recent novel methods presented in this review form essence improvements PSCs. morphology also influences charge‐transfer behavior device's lifetime.

Abstract The fabrication of perovskite solar cells (PSCs) under full‐air conditions accelerates their scalable production and industrialization. However, ambient moisture interacts with perovskites during the film formation that disturbs crystallization triggers structural imperfections. Here, a formamidine (FA) active addition reaction (FAAR) strategy is devised to intercept deleterious chemical coordination. simultaneous incorporation 2, 6‐bis(aminomethyl)pyridine (BAMPy) molecule into tin oxide surface bulk ameliorates interface contact interior. It found tail amino group from BAMPy selectively reacts FA cation, occupying A site crystals, increasing binding energy H 2 O even in defective surface, thereby strengthening tolerance. This effectively modifies air, favors uniformity, forms compressive‐strained films. FAAR‐modified PSC devices fabricated deliver highest efficiencies 24.11% 21.68% aperture areas 0.06 1 cm , respectively. favorable impediment property contributes enhancement maintaining 90.8% initial performance for encapsulated after 2400 h storage accelerating damp‐heat measurements (85 °C 85% relative humidity).
