In this study
wide bandgap (WBG) two-dimensional (2D) copolymer donors (
DZ1
DZ2
and
DZ3
) based on benzodithiophene (BDT) on alkoxyphenyl conjugated side chains without and with different amounts of chlorine atoms and difluorobenzotriazole (FBTZ) are designed and synthesized successfully for efficient non-fullerene polymer solar cells (PSCs). Three polymer donors
DZ1
DZ2
and
DZ3
display similar absorption spectra at 300−700 nm range with optional band-gap (
E
g
opt
) of 1.84
1.92
and 1.97 eV
respectively. Compared with reported
DZ1
without chlorine substitution
it is found that introducing chlorine atoms into the
meta
-position of the alkoxyphenyl group affords polymer possessing a deeper the highest occupied molecular orbital (HOMO) energy level
which can increase open circuit voltage (
V
OC
) of PSCs
as well as improve hole mobility. Non-fullerene bulk heterojunction PSCs based on
DZ2
:MeIC demonstrate a relatively high power conversion efficiency (PCE) of 10.22% with a
V
OC
of 0.88 V
a short-circuit current density (
J
SC
) of 17.62 mA/cm
2
and a fill factor (FF) of 68%
compared with PSCs based on
DZ1
:MeIC (a PCE of 8.26%) and
DZ3
:MeIC (a PCE of 6.28%). The results imply that adjusting chlorine atom amount on alkoxyphenyl side chains based on BDT polymer donors is a promising approach of synthesizing electron-rich building block for high performance of PSCs.
