All‐Polymer Solar Cells In article number 2103239, Bumjoon J. Kim, Yun‐Hi Kim and co‐workers develop a series of polymer acceptors with controlled backbone regioregularities and side chain structures. All‐polymer solar cells based on a RRg‐C20 acceptor which has a regioregular backbone and optimal side chain length achieve a high power conversion efficiency of 15.12%, attributed to high electron mobility and optimal blend morphology.
