obtained after annealing. For example, the EQE maxima of
the PTB7-Th:TT-OBAR devices increased from 20 to 23%
by SVA treatment. In addition, the introduction of the third
component having complementary UV–Vis absorption
spectra could further improve device performances.
AFM images were obtained to characterize the film mor-
phologies and are shown in Figures 4 and S4. The
PTB7-Th:TT-BBAR blend film displayed a rougher sur-
face with a root-mean-square (RMS) roughness of 11.7 nm,
whereas the blend film prepared using PTB7-Th:TT-
OBAR had very smooth surface with a RMS of 1.18 nm.
TT-OBAR formed a more homogeneous film compared to
TT-BBAR. In other words, the longer alkyl chain of TT-
OBAR may have improved the small molecule solubility
and morphology, thereby providing better JSC and PCE
values for the PTB7-Th:TT-OBAR blend film.

Conclusion
We synthesized two non-fullerene small molecule accep-
tors, TT-BBAR, and TT-OBAR, containing alkyl-
substituted BAR end groups. They have sufficient solubility
and thermal stability for application in OPV devices. The
electrochemical and optical properties of TT-BBAR and
TT-OBAR were found be similar, regardless of the alkyl
chain length; however, a smoother and more homogeneous
film morphology was obtained from the TT-OBAR-based
blend film, due to the longer alkyl chain and the better solu-
bility of TT-OBAR. The PTB7-Th:TT-OBAR device
