A direction modulation of intramolecular electric field (IEF) strategy is demonstrated to be a crucial factor to improve the charge transport capabilities of conjugated molecules. Furthermore, we obtain a set of empirical formulas to provide a potential approach to rapidly assess the hole transport properties based on molecular structure. Such a modulation results in a record performance of 23.41 % for perovskite solar cells based on phthalocyanine as dopant-free hole transport material. The greatly improved device stability is also obtained.

分子内电场的方向调制促进了钙钛矿太阳能电池酞菁中的空穴传输

分子内电场（IEF）的方向调制策略被证明是提高共轭分子电荷传输能力的关键因素。此外，我们获得了一组经验公式，提供了一种基于分子结构快速评估空穴传输特性的潜在方法。这种调制导致基于酞菁作为无掺杂空穴传输材料的钙钛矿太阳能电池的性能达到创纪录的 23.41%。器件稳定性也得到了大大提高。
