Abstract
Synthesis and photovoltaic properties of two donor–acceptor
polymers containing benzodithiophene with 3,3′,5-trihexylbithienyl
substituents are reported. Benzo[<i>c</i>][1,2,5]thiadiazole
and 5-hexylthieno[3,4-<i>c</i>]pyrrole-4,6-dione were used
as acceptor building blocks for the synthesis of donor–acceptor
polymers. The photovoltaic properties of the synthesized donor–acceptor
polymers were investigated in bulk heterojunction solar cells with
[6,6]-phenyl-C<sub>61</sub>-butyric acid methyl ester (PCBM) acceptor
