Incorporating a vertical BDT unit in conjugated polymers for drastically improving the open-circuit voltage of polymer solar cells

F-Substituted oligothiophenes were designed and used as nonfullerene acceptors in BHJ solar cells. With low-bandgap polymer donors, the solar cell devices reach PCEs of up to 4.5% and open-circuit voltages >1 V.
