N2 - In this work, an alcohol-soluble, low-temperature processable and relatively thickness insensitive electron-transporting layer (ETL) comprising a planar coronene derivative, CDIN, was exploited to effectively enhance the photovoltaic performance of various inverted organic photovoltaics (OPVs). Besides the decent charge-transporting property, such CDIN ETL was manifested to facilitate the face-on orientation of atop bulk-heterojunction (BHJ) layers as evidenced by GIWAXS analysis, which might benefit from its discotic geometry endowed with strong face-on π–π stacking in solid-states and better compatibility to the constituent organic photoactive components. Consequently, an enhancement of over 9% in PCE can be achieved in the state-of-the-art fullerene-based OPVs to yield a PCE of 11.2% while over 13% enhancement can be realized in the representative non-fullerene OPVs to yield a PCE of 9%.
