A novel wide‐bandgap copolymer (PDBT‐T1) is developed and applied in organic solar cells, which yield a high efficiency of 9.74% and a high fill factor of 75%. The high photovoltaic performance is due to efficient photogenerated exciton dissociation and charge collection in PDBT‐T1‐based solar cells. The results show that PDBT‐T1 is an outstanding candidate as a wide‐bandgap material for tandem (or multi‐junction) organic solar cells.
