POLYMERS CONTAINING 3' -(ALKOXY)-[2,2'-BITHIOPHENE] -3- CARBONITRILE FOR HIGH PERFORMANCE ORGANIC PHOTOVOLTAICS

Abstract:

A novel AB-type copolymer for use in organic photovoltaics. The AB-type copolymer comprises a unit A, where the unit A is ##STR00001## where R.sub.1 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: ##STR00002## wherein X.sub.1, X.sub.2, X.sub.3, and X.sub.4 are independently selected from the group consisting of: H, Cl, F, CN, alkyl, alkylthiol, alkoxy, ester, ketone, amide and aryl groups.
