Abstract

Molecular tailoring of self-assembled hole-transporting monolayers (SAMs) has been proven as an efficient approach for improving the device performance of inverted perovskite solar cells. Herein, a novel SAM with extended conjugation is designed and synthesized, named NaPh-4PACz. Compared to Ph-4PACz, NaPh-4PACz exhibits a larger adsorption energy with the ITO substrate, enabling the formation of a more uniform and dense film, thereby preventing direct contact between the perovskite and ITO. Additionally, NaPh-4PACz also has a stronger interaction with the perovskite, which can reduce buried interface defects and suppress non-radiative recombination. Consequently, NaPh-4PACz-based devices achieved a power conversion efficiency of 25.48 % due to their interfacial “adhesive” ability. Importantly, the stability of the NaPh-4PACz-based devices was significantly improved.

采用具有增强界面相互作用的自组装空穴传输单层的高效稳定的倒钙钛矿太阳能电池

自组装空穴传输单层（SAMs）的分子定制已被证明是提高倒置钙钛矿太阳能电池器件性能的有效途径。本文设计并合成了一种新型扩展共轭SAM，命名为NaPh-4PACz。与Ph-4PACz相比，NaPh-4PACz对ITO底物具有更大的吸附能，能够形成更均匀致密的薄膜，从而防止钙钛矿与ITO直接接触。此外，NaPh-4PACz还与钙钛矿具有较强的相互作用，可以减少界面埋藏缺陷，抑制非辐射复合。因此，基于naph - 4pacz的器件由于其界面“粘合”能力，实现了25.48%的功率转换效率。重要的是，基于nph - 4pacz的器件的稳定性得到了显著提高。
