In article number 1703070, Won Suk Shin, Bumjoon J. Kim, and co-workers describe the importance of the design of polymer donor-polymer acceptor pair to achieve complementary light absorption in all-polymer solar cells (all-PSCs). Synthetic donor-acceptor random copolymers with tunable light absorption characteristics were developed, which resulted in high performance all-PSC with a power conversion efficiency of 6.8%.
