Low-Dimensional Ligand-Driven Design of 2D/3D Perovskite Heterojunctions: Achieving Mitigated Nonradiative Recombination and Robust Stability for Next-Generation Solar Cells

Nano Letters, Journal Year: 2025, Volume and Issue: unknown

Published: May 5, 2025

Achieving efficient and stable perovskite solar cells (PSCs) is challenging due to nonradiative recombination, ion migration, film instability. This study designs low-dimensional (LD) ligands─benzimidazole (BIZ), 1H-benzimidazole, 6-methyl-, (6-MeBIm), 6-(trifluoromethyl)-, (6-TFBIm)─to construct LD/3D heterojunctions. Compared with BIZ 6-MeBIm (constructing 1D/3D heterojunction), the 2D/3D heterojunction constructed by 6-TFBIm successfully passivated different defects, resulting in a significant reduction recombination improved carrier transport, leading power conversion efficiency (PCE) of 25.25%, outperforming control devices (PCE: 22.97%). The PSCs exhibit superior humidity thermal stability, maintaining structural integrity under harsh conditions. These results underscore role tailored LD ligands optimizing quality, charge paving way for high-performance durable PSCs.
