Abstract The rapid crystallization process of perovskite produces a large number defects that remain critical factor disturbs the performance solar cells (PSCs). In this research, these challenges are mitigated by introducing multifunctional 2,6‐pyridinedicarboxylic acid chloride (PAC) as an additive into perovskite. During thermal annealing process, predominant accumulation PAC occurs at upper and buried interfaces film. possesses multiple passivating sites facilitate anchoring lead iodine defects, thereby enhancing quality material across both its dual grain boundaries. With unique property, combined with advantages enhanced crystallization, reduced non‐radiative recombination, boosted charge carrier mobility, optimal energy level alignment, PSC achieved power conversion efficiency (PCE) 25.60% maintained more than 90% after 3000 h under one equivalent light 1400 dark high temperature (85 °C). interface passivation strategy provides sustainable solution to stability environmental for commercialization cells.

Self‐Assembled Charge Bridge Path at the Sn‐Pb Perovskite/C₆₀ Interface for High‐Efficiency All‐Perovskite Tandem Solar Cells

Small, Год журнала: 2025, Номер unknown

Опубликована: Янв. 31, 2025

Narrow bandgap mixed tin-lead perovskite solar cells (PSCs) have garnered substantial research interest owing to their remarkable optoelectronic properties. However, non-radiative recombination and carrier transport losses at the interface between layer charge (C60) significantly reduce overall efficiency of PSCs. To address this challenge, 9-Fluorenylmethyl carbazate (9FC) is incorporated C60. The hydrazide group present in 9FC effectively mitigates oxidation Sn2+. Furthermore, can engage chemical bonding with perovskite, while outward-facing aromatic rings create effective π-π interactions C60, thereby promoting enhanced interfacial transfer. highest-performing PSCs achieve a power conversion (PCE) 23.97%, accompanied by an impressive open-circuit voltage 0.91 V. Additionally, these facilitate development highly efficient two-terminal four-terminal all-perovskite tandem cells, which demonstrate efficiencies 27.01% 28.07%, respectively.

Abstract The buried interface of wide‐bandgap (WBG) perovskite solar cells (PSCs) is crucial for effective charge transfer and device stability. In this study, 2,4‐diamino‐6‐fluoropyrimidine (DMFP) incorporated into the layer to form a molecular bridge at between MeO‐4PACZ. DMFP treatment reduces agglomeration MeO‐4PACZ, resulting in denser more uniform self‐assembled monolayers (SAMs) by inducing favorable crystal orientation. addition, strong chemical interaction films significantly defect state density promotes growth high‐quality grains. Moreover, effectively modulates energy levels perovskites, facilitating interfacial extraction. As result, WBG PSCs treated with demonstrate remarkable power conversion efficiency (PCE) 21.96%, an enhanced short‐circuit current (J SC ) 21.60 mA cm −2 high open‐circuit voltage (V OC 1.23 V. prepared retain 95.5% their initial after 1500 h aging relative humidity ≈30% air, indicating excellent This study contributes deeper understanding proposes collaborative approach developing high‐performance PSCs.

Regulating Precursor Viscosity with Inert Solvent Additives for Efficient Blade‐Coated Perovskite Solar Cells

Small Methods, Год журнала: 2025, Номер unknown

Опубликована: Фев. 24, 2025

Abstract Metal halide perovskite solar cells (PSCs) are emerging as promising candidates for next‐generation photovoltaics aimed at green energy production. However, during solution‐processed film deposition, the distinct rheological behaviors of blade coating, compared to spin result in less controlled crystallization, leading inferior quality and limiting power conversion efficiency (PCE) blade‐coated photovoltaics. In this work, ethylene glycol (EG) is introduced an inert co‐solvent precursor solutions achieve high‐quality films via coating. The high viscosity EG facilitates deposition thick ranging from 400 2000 nm, while its low vapor pressure effectively suppresses premature nucleation before vacuum flashing, with enhanced morphology. As a result, PSCs impressive champion PCE 24.10% retain 89% their initial after 600 h continuous operation.
