摘　　要：All-small-molecule organic solar cells (ASM OSCs) are promising for commercial application due to the well-defined chemical structures, convenient purifying process and low batch-to-batch variation. However, the similarity of molecule structures between small molecule donors and acceptors makes a hard regulation of their blend morphology, which will limit the efficiency.
