A wide-bandgap D-A copolymer donor based on a chlorine substituted acceptor unit for high performance polymer solar cells
Realizing the triple functions of simultaneously improved open circuit voltage ( V oc ), short circuit current density ( J sc ) and fill factor (FF) enabled by material design is a vital challenge for achieving efficient and stable polymer solar cells (PSCs). Herein, we developed a new wide-bandgap...

| description | Realizing the triple functions of simultaneously improved open circuit voltage (
V
oc
), short circuit current density (
J
sc
) and fill factor (FF) enabled by material design is a vital challenge for achieving efficient and stable polymer solar cells (PSCs). Herein, we developed a new wide-bandgap donor-acceptor (D-A) copolymer, J101, with a down-shifted highest occupied molecular orbital (HOMO) level by chlorine substitution on its 2-alkyl-benzo[
d
][1,2,3]triazole (BTz) unit. The PSCs fabricated by combining the J101 donor with the indenoindene-containing fused-ring electron acceptor ZITI demonstrated a remarkable power conversion efficiency (PCE) of 14.43% with a high
V
oc
of 0.937 V, a high
J
sc
of 21.25 mA cm
−2
and a high FF of 72.48%, benefitting from the low HOMO level of the donor, suitable nanoscale morphology, efficient charge transport properties and reduced recombination losses. Furthermore, semitransparent PSCs based on the optimized J101:ZITI blend exhibited the best PCE of 11.04% with an average visible transmittance (AVT) of 21.69%. This work demonstrates that the chlorine substituted BTz unit is an excellent electron-accepting building block for high-performance opaque and semitransparent PSCs.
A new wide-bandgap chlorinated polymer, J101, was synthesized and successfully used as the donor polymer for application in non-fullerene PSCs, and the PSCs fabricated by combining the J101 donor with the electron acceptor ZITI demonstrated a remarkable PCE of 14.43%. |
