摘要

电子传输层（ETL）和钙钛矿活性层（PVK）之间的埋藏界面是实现高性能钙钛矿太阳能电池（PSCs）的关键。能级不匹配和界面接触不良影响了效率和稳定性。本研究引入6-（三氟甲基）吡啶-3-氨基盐化物（TFPCl）建立偶极子界面。TFPCl的引入不仅通过其偶极子特性优化了能级，便于载流子的提取和输运，而且通过双锚定加强了ETL和PVK之间的界面接触，从而增强了稳定性。钙钛矿质量的提高以及对SnO2和钙钛矿缺陷的有效钝化优化了器件的光伏性能。因此，tfpcl调制的PSC实现了25.10%的功率转换效率（PCE），并证明了1500 h的环境存储稳定性。本研究通过在ETL/PVK埋藏界面中引入偶极子分子来提高PSC的光伏性能和稳定性，这是一种简单而有效的方法。

Double-anchored dipole buried interface enabling high-performance perovskite solar cells

A robust buried interface between electron transport layer (ETL) and perovskite active layer (PVK) is essential for achieving high-performance perovskite solar cells (PSCs). Energy level mismatches and poor interfacial contact hinder both efficiency and stability. In this study, we introduce 6-(trifluoromethyl)pyridine-3-amidine hydrochloride (TFPCl) to establish a dipole interface. The introduction of TFPCl not only optimizes the energy levels through its dipole characteristics, facilitating the extraction and transportation of carriers, but also reinforces the interfacial contact between ETL and PVK through dual anchoring, thereby enhancing stability. The improved perovskite quality and effective passivation of defects in SnO₂ and perovskite optimized the device's photovoltaic performance. Consequently, the TFPCl-modulated PSC achieves a power conversion efficiency (PCE) of 25.10% and demonstrates environmental storage stability of 1500 h. This study demonstrates a simple yet effective approach for enhancing the photovoltaic performance and stability of PSCs by introducing a dipole molecule into the ETL/PVK buried interface.
