Abstract Organic‐inorganic hybrid perovskites have emerged as highly promising candidates for photovoltaic applications, owing to the exceptional optoelectronic properties and low cost. Nonetheless, performance stability of solar cells suffer from defect states perovskite films aroused by non‐optically active phases non‐centralized crystal orientation. Herein, a versatile organic molecule, Hydantoin, modulate crystallization perovskite, is developed. Benefiting diverse functional groups, more spatially oriented with high crystallinity are formed. This enhancement accompanied conspicuous reduction in density, yielding efficiency 25.66% (certified 25.15%), superb environmental stability. Notably, under standard measurement conditions (ISOS‐L‐1I), maximum power point (MPP) output maintains 96.8% initial 1600 h exhibits excellent ion migration suppression. The synergistic regulation spatial orientation offers novel avenues propelling cell (PSC) development.

Enhancing Efficiency of Industrially‐Compatible Monolithic Perovskite/Silicon Tandem Solar Cells with Dually‐Mixed Self‐Assembled Monolayers

Advanced Functional Materials, Год журнала: 2024, Номер 34(46)

Опубликована: Июнь 22, 2024

Abstract The antisolvent‐assisted spin‐coating still lags behind the thermal evaporation method in fabricating perovskite films atop industrially textured silicon wafers making monolithic perovskite/silicon solar cells (P/S‐TSCs). inhomogeneity of hole‐selective self‐assembled monolayers (SAMs) often arises from insufficient bonding between hygroscopic phosphonic acid anchors and metal oxide. To address this, a mixed‐SAM strategy (Mx‐SAM) is proposed to enhance adsorption energy SAMs on ITO surface, facilitate formation dense humidity‐resistant layer (HSL) substrates, improve hole transport capabilities. With aid Mx‐SAM strategy, optimized wide‐bandgap PSCs achieved an impressive power conversion efficiency (PCE) 22.63% with exceptionally high fill factor ( FF ) 86.67% using 1.68 eV perovskite. Moreover, they exhibited enhanced stability under damp‐heat conditions (ISOS‐D‐3, 85% RH, 85 °C) T 90 900 h for encapsulated PSCs, representing one best performances PSCs. When further extending P/S‐TSCs industry, remarkable 28.07% reached while upholding outstanding reproducibility. This holds significant promise feasibility industrially‐compatible P/S‐TSCs.

Spatially Isomeric Fulleropyrrolidines Enable Controlled Stacking of Perovskite Colloids for High‐Performance Tin‐Based Perovskite Solar Cells

Angewandte Chemie International Edition, Год журнала: 2025, Номер unknown

Опубликована: Янв. 3, 2025

Abstract The advancement of tin‐based perovskite solar cells (TPSCs) has been severely hindered by the poor controllability crystal growth and energy level mismatch between fullerene‐based electron transport layer (ETL). Here, we synthesized three cis‐configured pyridyl‐substituted fulleropyrrolidines (PPF), specifically 2‐pyridyl (PPF2), 3‐pyridyl (PPF3), 4‐pyridyl (PPF4), utilized them as precursor additives to regulate crystallization kinetics during film formation. spatial distance two pyridine groups in PPF2, PPF3, PPF4 increases sequentially, enabling interact with more colloidal particles. These interactions effectively enlarge colloid size decelerate rate perovskite, resulting high‐quality PPF4‐based films reduced defect density lower exciton binding energy. Additionally, incorporated a well‐defined fullerene bis‐adduct, C 60 BB, an interlayer PCBM layers optimize alignment. Through synergistic effects our champion device achieved efficiency 16.05 % (certified: 15.86 %), surpassing 16 bottleneck setting new benchmark for TPSCs. Moreover, devices exhibited outstanding stability, retaining 99 their initial after 600 hours maximum power point tracking under 1 sun condition.
