In　inverted　perovskite　solar　cells　(PSCs),　the　fullerene　derivative　[6,6]-phenyl-C-61-butyric　acid　methyl　ester　(PCBM)　is　a　widely　used　electron　transport　material.　However,　a　high　degree　of　energy　disorder　and　inadequate　passivation　of　PCBM　limit　the　efficiency　of　devices,　and　severe　self-aggregation　and　unstable　morphology　limit　the　lifespan　of　devices.　Here,　we　design　a　series　of　fullerene　dyads　FP-Cn　(n　=　4,　8,　12)　to　replace　PCBM　as　an　electron　transport　layer,　where　[60]fullerene　is　linked　with　a　terpyridine　chelating　group　via　a　flexible　alkyl　chain　of　different　lengths　as　a　spacer.　Among　three　fullerene　dyads,　FP-C8　shows　the　most　enhanced　molecule　ordering　and　adhesion　with　the　perovskite　surface　due　to　the　balanced　decoupling　between　the　chelation　effect　from　terpyridine　and　the　self-assembly　of　fullerene,　leading　to　lower　energy　disorder　and　higher　morphological　stability　relative　to　PCBM.　The　FP-C8/C60-based　devices　using　Cs(0.05)FA(0.90)MA(0.05)PbI(2.85)Br(0.15)　as　a　light　absorber　show　a　power　conversion　efficiency　of　21.69%,　higher　than　that　of　PCBM/C60　(20.09%),　benefiting　from　improved　electron　extraction　and　transport　as　well　as　reduced　charge　recombination　loss.　When　employing　FAPbI(3)　as　a　light　absorber,　the　FP-C8/C60-based　devices　exhibit　an　efficiency　of　23.08%,　which　is　the　champion　value　of　inverted　PSCs　with　solution-processed　fullerene　derivatives.　Moreover,　the　FP-C8/C60-based　devices　show　better　moisture　and　thermal　stability　than　PCBM/C60-based　devices　and　maintain　96%　of　their　original　efficiency　after　1200　h　of　operation,　while　their　counterpart　PCBM/C60　maintains　60%　after　670　h.
