By controlling the polymer/polymer blend self‐organization rate , all‐polymer solar cells composed of a high‐mobility, crystalline, naphthalene diimide‐selenophene copolymer acceptor and a benzodithiophene‐thieno[3,4‐ b ]thiophene copolymer donor are achieved with a record 7.7% power conversion efficiency and a record short‐circuit current density (18.8 mA cm −2 ).
