摘要	The rapid development of all-small-molecule solar cell has recently gained recognition within the photovoltaic research community. Well-defined structure and less batch-to-batch variation empowered it great application prospects. In this perspective, we review the development of small molecule donors based on benzodithiophene (BDT) and its derivatives, with a focus on the relationship between molecule structure, stacking characteristics and device performance. By analyzing successful cases in the BDT series of small molecules, we aim to clarify the link between molecule structure, solid-state aggregation and device performance. We hope this discussion can be the minnow to catch the whale of highly efficient molecules in the future.
