摘要

Abstract

To design high efficiency polymer solar cells (PSCs)

it is of great importance to develop suitable polymer donors that work well with the low bandgap acceptors

providing complementary absorption

forming interpenetrating networks in the active layers and minimizing energy loss. Recently

we developed a series of two-dimension-conjugated polymers based on bithienylbenzodithiophene-

alt

-benzotriazole backbone bearing different conjugated side chains

generally called

-series polymers. They are medium energy bandgap (

) polymers (

. 1.80 eV) with strong absorptions in the range of 400−650 nm

and exhibit ordered crystalline structures

high hole mobilities

and more interestingly

tunable energy levels depending on the structure variations. In this feature article

we highlight our recent efforts on the design and synthesis of those

-series polymer donors

including an introduction on the polymer design strategy and emphasis on the crucial function of differential conjugated side chain. Finally

the future opportunities and challenges of the

-series polymers in PSCs are discussed.
