Forming an ideal bulk heterojunction (BHJ) morphology is a critical issue governing the photon to electron process in organic solar cells (OSCs). Complementary to the widely‐used blend casting (BC) method for BHJ construction, sequential casting (SC) can also enable similar or even better morphology...
