A double-fibril network of the photoactive layer morphology is recognized as an ideal structure facilitating exciton diffusion and charge carrier transport for high-performance organic solar cells (OSCs). However, in layer-by-layer processed OSCs (LbL-OSCs), polymer donors small molecule acceptors (SMAs) are separately deposited, it challenging to realize a fibril pure SMAs with absence tight interchain entanglement polymers. In this work, crystalline (SMDs), named TDZ-3TR SeDZ-3TR, were designed introduced into L8-BO acceptor solution, forcing phase separation molecular fibrilization. SeDZ-3TR showed higher crystallinity lower miscibility than TDZ-3TR, enabling more driving force favor better fibrilization L8-BO.
