In article number 1801601 , Hae Jung Son and co‐workers develop donor‐acceptor‐type random copolymers. Nonfullerene polymer solar cells (PSCs) that utilize the resulting polymer achieve a high efficiency of 11.14%. Furthermore, the plastic substrate‐based flexible PSC using a random copolymer PBDB‐T73 shows much higher efficiency of 10.02% compared to 7.2% of the corresponding PBDB‐T device due to low‐temperature processability of the PBDB‐T73 polymer.
