NOVEL BLOCK COPOLYMERS, METHODS OF PREPARATION AND THEIR USE IN HETEROJUNCTION DEVICES

摘要

The invention relates to novel block copolymers having both electron donor and electron acceptor monomer units and to methods for their preparation. A further aspect of the invention relates to the use of the novel block copolymers in the fabrication of polymer film based heterojunction devices. In one form the devices display high conversion efficiencies in solar cell applications.
