摘要
钙钛矿太阳能电池(PSCs)因其性能优异、成本低廉和制备工艺简单,在环境、生态和能源结构调整方面具有重要意义.其中空穴传输材料(HTMs)有效调节电池界面势垒、促进空穴传输和收集、降低电荷复合、优化钙钛矿层与电极界面以及改善钙钛矿光吸收层的性质,在PSCs中发挥重要的作用.氟取代材料具有独特的电荷传输特性和光电性能,向有机分子中引入具有诱导效应和共轭效应的氟原子可以降低分子能级,提高HTMs的空穴迁移率,进而提高PSCs的性能.此综述对氟取代有机空穴传输材料对PSCs光电性能的影响及其作用机制进行了梳理和总结.
Abstract
Perovskite solar cells(PSCs)are of significant importance in the fields of environment,ecology,and energy struc-ture adjustment due to their exceptional performance,cost-effectiveness,and straightforward preparation process.Among them,hole transport materials(HTMs)play a crucial role in PSCs by effectively regulating the battery interface barrier,facili-tating hole transport and collection,reducing charge recombination,optimizing the perovskite layer-electrode interface,and enhancing the properties of perovskite light absorption layer.Fluorine-substituted materials possess unique charge transport and photoelectric properties.The introduction of fluorine atoms into organic molecules through induction and conjugation effects can lower molecular energy levels,improve HTM hole mobility thereby enhancing PSCs performance.This paper pro-vides a comprehensive review and summary on the impact of fluorine-substituted organic hole transport materials on the pho-toelectric properties of PSCs as well as their underlying mechanisms.
