Abstract

Although buckminsterfullerene (C₆₀) is usually the electron transport layer (ETL) in inverted perovskite solar cells (PSCs), its molecular nature leads to weak interfaces that result in nonideal interfacial electronic and mechanical degradation. In this study, we synthesized an ionic salt from C₆₀, 4-(1′,5′-dihydro-1′-methyl-2′H-[5,6] fullereno-C₆₀-I_h-[1,9-c]pyrrol-2′-yl) phenylmethanaminium chloride (CPMAC), and used it as the electron shuttle in inverted PSCs. The CH₂-NH₃⁺ head group in the CPMA cation improved the ETL interface, and the ionic nature enhanced the packing, leading to a ~threefold increase in the interfacial toughness compared with that of C₆₀. Using CPMAC, we obtained ~26% power conversion efficiencies (PCEs) with ~2% degradation after 2100 hours of 1-sun operation at 65°C. For minimodules (four subcells, 6 square centimeters), we achieved a PCE of ~23% with <9% degradation after 2200 hours of operation at 55°C.

高性能倒置钙钛矿太阳能组件用c60基离子盐电子穿梭

虽然c60通常是倒置钙钛矿太阳能电池中的电子传递层（ETL），但其分子性质导致弱界面，导致非理想的界面电子和机械退化。本文以c60,4 -（1',5 '-二氢-1'-甲基-2' H -[5,6]富勒烯- c60,4 - I H -[1,9- C]吡咯-2'-基）苯基甲基氯化铵（CPMAC）为原料合成了离子盐，并将其用作反向PSCs的电子穿梭体。CPMA阳离子中的ch2 - nh3 +头基团改善了ETL界面，离子性质增强了填料，使界面韧性比c60提高了约3倍。使用CPMAC，我们在65°C下1太阳运行2,100小时后获得了~26%的功率转换效率（pce）和~2%的退化。对于微型模块（四个亚电池，6厘米平方），在55°C下运行2200小时后，我们实现了~23%的PCE和<；9%的降解。

期刊介绍： Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
