Abstract
A novel AB-type copolymer for use in organic photovoltaics. The AB-type copolymer comprises a unit A, where the unit A is where R1 is a carbon chain from about 1 to about 30 units and where Y is selected from CN, F and Cl. The B unit of the AB-type copolymer is selected from is selected from: wherein X1, X2, X3, and X4 are independently selected from the group consisting of: H, Cl, F, CN, alkyl, alkylthiol, alkoxy, ester, ketone, amide and aryl groups.
