The quality of organic-inorganic hybrid perovskite films directly affects the application prospect solar cells (PSCs), where organic and inorganic cations are core elements that affect perovskite. additive strategy has been widely used to passivate cation-related defects in films. Here, precursor solution introduced 5-bromopyridine-3-sulfonic acid (BOH) with a potential all-cation passivation function. experimental results verified N atom on pyridine BOH molecular structure passivated by binding undercoordination Pb2+, sulfonic group inhibited nonradiative recombination through their interactions FA+ improving grain size crystallinity, enhancing film quality. Thanks all-cationic targeted anchoring effect BOH, efficiency BOH-treated device upgraded from 22.32 24.33%. Importantly, PSCs showed excellent stability after exposure 25% humidity for 1200 h at room temperature.

The premature reaction of PbI 2 with organic cations in perovskite (PVK) precursor solutions often leads to compromised film quality. To mitigate this, the ionic liquid (IL) pyridinium trifluoromethanesulfonate is introduced into solution. strong interaction between and promotes formation nucleation clusters, effectively lowering barrier regulating crystallization perovskite, resulting high‐quality, homogeneous PVK films. In situ characterization shows that prenucleation strategy yields films an average grain size exceeding 1 μm. hydrophobicity trifluoromethyl group modulates humidity, facilitating moist environments. This contrast typical negative effects moisture, which can induce defects structures. As a result, IL‐modified solar cells (PSCs) achieved remarkable power conversion efficiency (PCE) 25.11% under ambient conditions. These PSCs retained 80.43% their initial PCE after 820 h continuous maximum point (MPP) tracking. Furthermore, 1000 exposure air 30%–50% relative humidity (RH) at room temperature, devices maintained 87% efficiency, demonstrating excellent stability for long‐term PSC applications.

Abstract Diammonium derivatives with electron‐withdrawing cores of cyclohexyl or phenyl have demonstrated enormous potential in achieving high‐performance perovskite solar cells. Nevertheless, the critical role these diammonium passivation on device performance is yet to be elucidated. Herein, two kinds ligands 1, 4‐cyclohexyldimethylammonium diiodide (CyDMADI) and 4‐phenyldimethylammonium (PhDMADI) are introduced into precursor for bulk passivation. The PhDMADI system exhibits a stronger unit comparison CyDMADI core, thus resulting enhanced electrostatic interaction between uncoordinated Pb 2+ groups hydrogen bonds I─Pb skeleton. Such strengthened interactions effectively inhibit generation trap states therefore significantly decrease non‐radiative recombination. PhDMADI‐passivated film demonstrates mitigated microstrain decreased grain boundary grooves （GBGs） compared CyDMADI‐based counterpart. Simultaneously, treatment can efficiently slow down hot‐carriers cooling dynamics process, benefiting transfer hot‐carriers. Consequently, achieves an impressive efficiency 26.04%, along excellent operating stability which retains 90% its initial after 1100 h tracking at maximum power point under continuous one sun illumination.

Abstract The performance of perovskite solar cells has significantly improved over the years in part due to defect passivation bulk and at interfaces. While many additive molecules have been reported literature, they are commonly applicable only one particular composition. Here we investigate a multifunctional additive, 4‐amino‐5‐bromo nicotinic acid (ABrNA), for use both methylammonium (MA)‐free perovskites with different Br content (bandgaps ranging from 1.53 1.73 eV) as well MA‐containing perovskites. Significant improvements obtained all compositions, which can be attributed presence multiple functional groups capable modifying crystallization passivating defects. Exceptional features ABrNA make it promising universal passivator, leads PCE increase 23.9% 25.0% CsFAMA cells, 22.0% 23.0% MA‐free cells. passivated devices also exhibit exceptional operational stability, T 90 exceeding 1000 h under ISOS‐L‐1 testing conditions. In addition, significant improvement is observed modules conventional inverted device architectures, further confirming universality additive.

Tin perovskites are considered promising candidates for realizing high-performance, lead-free perovskite solar cells (PSCs). Despite prominent progress made through bulk optimization, unsatisfactory interfaces between tin and charge transport layers critical obstacles to boosting device performance. Herein, we address this issue by introducing piperazine dihydroiodide (PDI) ferrocene (Fc) at the interface of perovskite/C60 synergistically improve interfacial transport. Specifically, PD+ interacts with formamidinium ions (FA+) form an dipole, Fc establishes π-π conjugation C60. These effects significantly electron extraction reduce energy losses. As a result, efficiency PSCs is remarkably improved from 10.62% 13.65%, accompanied enhanced stability. This work highlights importance modulation in toward efficient eco-friendly photovoltaics.
