Small molecular materials were synthesized to investigate the effect of donor molecular crystallinity on solar cell performance in small molecular solar cells. The photovoltaic properties of solar cells made of these new donor molecules are systemically studied with the [6,6]- phenyl-C71-butyric acid methyl ester (PC71BM) fullerene acceptor and the O-IDTBR non-fullerene acceptor to study the aggregation behavior and crystallinity of the donor molecules in both blends. Morphological analyses and a charge carrier dynamics study are carried out simultaneously to derive structure−property relationships and address the requirements of all-small-molecule solar cells.
