Theoretical and experimental scientists collaborate in the study of (A1‐D)‐(A2‐D) type random copolymers for organic photovoltaics. In the article on page 2792, Ali Cirpan and colleagues investigate the effectiveness of single‐atom replacement and altering the electronegativity of the substituents. Additionally, incorporating an additive can further improve the power conversion efficiency of random copolymer solar cells. (DOI: 10.1002/pol.20200513)
