High‐efficiency solution‐processed organic solar cells based on narrow‐bandgap π‐conjugated oligomers are demonstrated by Takuma Yasuda, Chihaya Adachi, and co‐workers in article number 1400879. Well‐organized donor/acceptor bulk‐heterojunction domains with pronounced mesoscopic phase segregation are spontaneously formed in a photoactive binary blend layer. A high power conversion efficiency of 5.9% is achieved for small‐molecule organic solar cells.
