In article 1500877, Thuc‐Quyen Nguyen, Harald Ade, and co‐workers demonstrate the connection between device performance and morphological parameters in organic photovoltaics. The results demonstrate the complex correlation between domain purity, size, and molecular ordering, and highlight the requirement of achieving sufficient average phase purity of donor and acceptor domains to diminish charge recombination losses in solution‐processed small‐molecule bulk heterojunction solar cells.
