The development of excellent electron transport layers (ETLs) is crucial for high-performance organic solar cells (OSCs). In this work, we have developed a novel, versatile ETL composed zinc oxide (ZnO) and fluorescent agent to enhance the photovoltaic performance photostability OSCs. Unlike bulk doping ZnO interlayer, use conjugated small-molecule agent, sodium 2,2'-([1,1'-biphenyl]-4,4'-diyldivinylene)-bis(benzenesulfonate) (CBS), modify surface thus construct ZnO/CBS bilayer structure. shows lower work function, which beneficial extraction. Moreover, photoinduced transfer from CBS increases conductivity ZnO. Notably, fluorescence generated by can also be quenched active layer, indicating existence exciton or charge between layer. bidirectional layer synergistically improves enhances performance. Consequently, PM6:eC9 PM6:L8-BO based OSCs with as achieve power conversion efficiencies 17.42 18.16%, respectively, are among highest levels in inverted thickness insensitivity PM6:eC9-based still exhibit high PCE 15.66% at thick-film 130 nm 20 CBS. addition, modification efficiently blocks ultraviolet light reduces catalytic activity thereby enhancing
