Molecular orientation plays a critical role in determing the performance of all‐polymer solar cells. In article number 1600504, Bumjoon J. Kim and co‐workers report an approach for tuning the molecular crystallinity and orientation of naphthalenediimide‐bithiophene‐based n‐type polymers (P(NDI2HD‐T2)) by controlling their number average molecular weights. The cover image depicts the bulk heterojunction all‐polymer solar cell with PTB7‐Th donor and P(NDI2HD‐T2) acceptor. The packing orientation of two polymers in thin film and at the interface is critical for producing high‐performance solar cells.
