Dual Potassium Salts Modulation of Perovskite Quality for Efficient Perovskite Photovoltaics

Ziming Yin, Sanwan Liu, Yifei Xu, Tianyin Miao et autres

ABSTRACT Solution processing of mixed‐halide perovskites inevitably leads to inferior crystallinity and introduces undesired defects, arising from inhomogeneous ion mixing in the precursor solution or rapid solvent evaporation and uncontrollable nucleation/growth, thereby impairing both the power conversion efficiency (PCE) and long‐term stability …

Molecular Suppression of PCBM Dimerization in Inverted Perovskite Solar Cells

Qiuhan Yu, Mubai Li, Tianyin Miao, Yixuan Zheng et autres

Inverted perovskite solar cells require robust electron‐transport layers (ETLs) to fully realize their potential in both efficiency and operational stability. The widely used ETL material phenyl‐C 61 ‐butyric acid methyl ester (PCBM) is intrinsically vulnerable to photo‐induced [2 + 2] cycloaddition, which …

Bisphosphonate‐Anchored Self‐Assembled Molecule with Halogen Functionalization for Wide‐Bandgap Perovskite Solar Cells and Tandems

He Zhu, Xiaodong Wang, Yi-Xiang Wang, Yafeng Xu et autres

ABSTRACT Wide‐bandgap (WBG) top subcells used in all‐perovskite tandems commonly suffer from substantial open‐circuit voltage ( V OC ) deficits, primarily caused by interfacial defects and non‐ideal energy alignment. Here, we develop bisphosphonate‐anchored indolocarbazole derivatives, bis‐4PACz and bis‐4PACz‐Br, as self‐assembled monolayer (SAMs) …

4‐Methylpyridine‐Mediated Homogenization of Wide‐Bandgap Perovskite Films for Efficient All‐Perovskite Tandem Solar Cells

Yi-Xiang Wang, Shijie Zheng, He Zhu, Tianyin Miao et autres

ABSTRACT Mixed‐halide wide‐bandgap (WBG) perovskites are promising top‑cell materials for multi‐junction photovoltaics owing to their tunable bandgap and excellent photoelectronic properties. However, their solution processing often suffers from mismatched crystallization kinetics between iodine and bromine species, leading to compositional inhomogeneity and limited …

An entropy-regulating molecular lock stabilizes formamidinium lead halide perovskite

Tianyin Miao, Sanwan Liu, Xia Lei, Yong Zhang et autres

A critical limitation of formamidinium lead iodide (FAPbI 3 ) perovskite solar cells (PSCs) lies in the intrinsic instability of the ionic–covalent Pb–I octahedral lattice, relative to the unfavorable hexagonal δ-phase under operating conditions. We report an entropy-regulating molecular-lock strategy using 1-pyridin-3-ylmethyl-piperazine …

Progress in High-Efficiency Inverted Perovskite Solar Cells: Charge Transport, Interface Engineering, and Stability

Sanwan Liu, Tianyin Miao, Yalan Zhang, Zonghao Liu et autres

Inverted (p-i-n) perovskite solar cells (PSCs) have emerged as a focal point in photovoltaic research, combining high efficiency with long-term stability and offering a strong potential for tandem integration. Their quasi-steady-state certified power conversion efficiencies (PCEs) now exceed 27%, surpassing those of …

Asymmetric Self‐Assembled Molecule With High Dipole Moment for Efficient Wide‐Bandgap Perovskite Solar Cells and Tandems

Jinhua Wang, Yixuan Hao, He Zhu, Shijie Zheng et autres

ABSTRACT Self‐assembled monolayers (SAMs) have shown considerable promise as hole‐transport layers (HTLs) in wide‐bandgap (WBG) perovskite solar cells (PSCs) and tandems. However, conventional SAM materials often face limitations such as substantial energy‐level misalignment and inefficient charge transport, which limit device performance. Here, …
