目前,广泛用于正型有机太阳能电池的空穴提取层(HEL)材料是PEDOT:PSS.然而, PEDOT:PSS的酸性会腐蚀氧化铟锡(ITO)电极,降低器件的稳定性.本文采用中心氟化策略,设计合成了一种双膦酸型自组装单分子层(SAM)材料3BPIC-cF.与PEDOT:PSS相比, 3BPIC-cF修饰的ITO基底具有更高的光透过率和更好的界面相容性.氟原子的引入使得3BPIC-cF具有更大的偶极矩和更深的最高占据轨道能级,导致ITO/3BPIC-cF基底具有比ITO/PEDOT:PSS基底更大的功函数.这些优势有利于空穴的提取,降低界面阻抗并抑制界面处的非辐射复合.使用3BPIC-cF作为HEL的有机太阳能电池实现了19.34%的光伏效率,优于PEDOT:PSS器件(PCE=18.64%).此外,基于3BPIC-cF的光伏器件具有比基于PEDOT:PSS的器件更高的稳定性.本研究为面向高效有机太阳能电池中SAM分子的设计与合成提供了有价值的指导.
