Hole transport materials (HTMs) exhibiting suitable electronic properties, fast hole transport, high hydrophobicity and good oxygen resistance are critical for realizing perovskite solar cells (PSCs) that are stable and exhibit high-performance. Manipulating the length of alkyl chains is a widely adopted strategy that can fine tune the properties of organic materials in order to enhance their performance for various applications. Yet, a systematic exploration of the influence of chain length on those properties most relevant to highly performing HTMs in PSCs is lacking. Multiscale simulations, along with morphological analyses, uncover relationships between alkyl chain length and HTM properties that provide important insights for the optimization of future organic materials.

烷基链长如何改变基于三苯胺的空穴传输材料的性能？†

空穴传输材料（HTM）表现出合适的电子性能，快速的空穴传输，高疏水性和良好的抗氧性对于实现稳定且具有高性能的钙钛矿太阳能电池（PSC）至关重要。操纵烷基链的长度是一种广泛采用的策略，可以微调有机材料的性能，以增强其在各种应用中的性能。然而，缺乏对链长对那些与PSC中高性能HTM最相关的特性的影响的系统研究。多尺度模拟以及形态分析揭示了烷基链长度与HTM性能之间的关系，这为优化未来的有机材料提供了重要的见识。
