A non-fullerene acceptor based on alkylphenyl substituted benzodithiophene for high efficiency polymer solar cells with a small voltage loss and excellent stability
In this work, a new non-fullerene small molecule acceptor (NF-SMA) named BP-4F , based on benzo[1,2- b :4,5- b ′]di(cyclopenta[2,1- b :3,4- b ′]dithiophene) with 4-(2-ethylhexyl)phenyl conjugated side chains (BDTP) as an electron-donating core, flanked with a strong electron-withdrawing 2-(5,6-diflu...

-inden-1-ylidene)-malononitrile (2FIC) unit, is designed and synthesized for polymer solar cell applications.
BP-4F
exhibits strong absorption in the 550 to 830 nm region with a narrow optical band gap of 1.49 eV, suitable energy levels with a lowest unoccupied molecular orbital (LUMO) of −3.90 eV and an effective electron mobility of 2.10 × 10

. When blended with the wide bandgap polymer
PM6
as the active layer, the polymer solar cells (PSCs) achieve an average power conversion efficiency (PCE) of 13.9% with an energy loss (
E

) as low as 0.59 eV, which is of benefit to overcome the trade-off between

and

. Furthermore, the
BP-4F
-based PSCs achieve an excellent PCE of 12.3% with a device area of 1.10 cm

. Notably, the devices show an excellent storage stability and photo-stability by retaining nearly 90% of the initial PCE in air under dark conditions and 93.5% in a glovebox under continuous illumination for 720 hours, respectively. These results indicate that
BP-4F
is an effective electron acceptor for high efficiency and stable polymer solar cells.
A new small molecule acceptor named BP-4F is developed. The optimal PSC based PM6:BP-4F achieves an excellent average PCE of 13.9% with an

of 0.59 eV and outstanding stability. |
