摘要

Abstract

To achieve the red-shifted absorptions and appropriate energy levels of A-D-A type non-fullerene acceptors (NFAs)

in this work

we design and synthesize two new NFAs

named TPDCIC and TPDCNC

whose electron-donating (D) unit is constructed by a thieno[3

]pyrrole-4

6-dione (TPD) core attached to two cyclopentadithiophene (CPDT) moieties at both sides

and the electron-accepting (A) end-groups are 2-(3-oxo-2

3-dihydroinden-1-ylidene)malononitrile (IC) and 2-(3-oxo-2

3-dihydro-1

-cyclopenta[

]naphthalen-1-ylidene)malononitrile (NC)

respectively. Benefiting from TPD core

which easily forms quinoid structure and O···H or O···S intramolecular noncovalent interactions

TPDCIC and TPDCNC show more delocalization of

-electrons and perfect planar molecular geometries

giving the absorption ranges extended to 822 and 852 nm

respectively. Furthermore

the highest occupied molecular orbital (HOMO) levels of TPDCIC and TPDCNC remain relatively low-lying due to the electronegativity of the carbonyl groups on TPD core. Considering that the absorptions and energy levels of the two NFAs match well with those of a widely used polymer donor

PBDB-T

we fabricate two kinds of organic solar cells (OSCs) based on the PBDB-T:TPDCIC and PBDB-T:TPDCNC blended films

respectively. Through a series of optimizations

the TPDCIC-based devices yield an impressing power conversion efficiency (PCE) of 10.12% with a large short-circuit current density (

) of 18.16 mA·cm

−2

and the TPDCNC-based ones exhibit a comparable PCE of 9.80% with a

of 17.40 mA·cm

−2

. Our work is the first report of the TPD-core-based A-D-A type NFAs

providing a good reference for the molecular design of high-performance NFAs.
