Abstract

We report two novel small-molecule non-fullerene acceptors,
IF-TN and IDT-TN, with indenofluorene (IF) and indacenodithiophene
(IDT) as their respective central electron-rich cores and naphthyl-fused
indanone (N) as the electron-withdrawing end-groups. By pairing these
non-fullerene acceptors with a widely used polymer PBDB-T, the fabricated polymer solar cells
based on PBDB-T:IDT-TN obtain a power conversion efficiency up to
5.89%, associated with a relatively high open-circuit voltage of 0.97 V
and a remarkably low non-radiative open-circuit voltage loss of 0.23 V.
These findings provide an effective approach for the rational molecular
design of small-molecule acceptors with low non-radiative open-circuit voltage loss.
