In this contribution, phenyl‐C61‐butyric acid methyl ester (PCBM) and α‐Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> synergistically worked together as the electron transport layer (ETL) in planar heterojunction perovskite solar cells. The introduction of fullerene at the top of the α‐Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> ETL improved the crystallinity of CH<jats:sub>3</jats:sub>NH<jats:sub>3</jats:sub>PbI<jats:sub>3</jats:sub> perovskite and facilitated electron extraction. As a consequence, a substantially retarded charge recombination largely boosted the short‐circuit current density and power conversion efficiency of perovskite solar cells. The optimized perovskite solar cells with α‐Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>/PCBM ETL showed a competitive power conversion efficiency of 14.2 %, which is 20 % higher than that of pristine α‐Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>‐based solar cells. Moreover, α‐Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>/PCBM‐based perovskite solar cells exhibited improved stability compared to the pristine α‐Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>‐based devices, retaining over 95 % of their initial values after 45 days storage in dark in humid air.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381418520151346305","@type":"Researcher","foaf:name":[{"@value":"Qinzhi Hou"}],"jpcoar:affiliationName":[{"@value":"State Key Laboratory of Electronic Thin Film and Integrated Devices University of Electronic Science and Technology of China  Chengdu 610054 P.R.
