摘要

Four selenium-fused NIR-absorbing acceptors were developed by tailoring the molecular photoelectric properties

via

end-group and side-chain dual engineering. Among them

Y-SeNF-2ClO with linear side chains and asymmetric end groups showed favorable molecular packing and energy levels

which optimized the active layer morphology and suppressed energy loss

achieving a high device efficiency of 20.08%.

Abstract

Although near-infrared (NIR)-absorbing acceptors tend to capture more photons to boost the photocurrent (

) of polymer solar cells (PSCs)

they often suffer from significant energy loss (

loss

)

resulting in a low photovoltage (

)

which limits further improvement of the power conversion efficiency (PCE). Herein

we developed four selenium-fused NIR-absorbing acceptors (Y-SeNF

Y-SeNF-2ClO

Y-SeBNF

and Y-SeBNF-2ClO) by regulating the molecular photoelectric properties

via

end-group and side-chain dual-engineering. Among them

Y-SeNF-2ClO with linear side-chains and asymmetric end-groups showed favorable molecular packing and energy leve

achieving an optimized active layer morphology and suppressed energy loss. Therefore

among the binary PSCs with a polymer donor D18

the Y-SeNF-2ClO device achieved the minimized

loss

and the highest product of

leading to a champion PCE of 17.41%

outperforming other devices based on acceptors with branched side-chains and/or symmetric end-groups. Encouraged by the above success

NIR-absorbing Y-SeNF-2ClO was also introduced into the classic D18:L8-BO host system to fabricate efficient ternary PSCs. Notably

the D18:L8-BO:Y-SeNF-2ClO device offered a further improved PCE of 20.08%

ranking among the highest values reported for asymmetric acceptors. This work provides a feasible molecular design strategy for end-group and side-chain dual-engineering to develop NIR-absorbing acceptors for constructing efficient PSCs.
