Organic photovoltaic cells(OPVs) have attracted considerable attention due to their unique features such as low cost, low weight, and capability to be fabricated into flexible large area devices by solution process. Recently, D-A polymers with conjugated side groups has been developed by several research group because normal D-A copolymers may suffer from lower hole mobility. This type of polymers feature high hole mobility benefiting from the overlapping of the conjugated side chain interactions with the conjugated main chains. Quinacridone, which is known as electron donor, has a high crystallinity, self-assembled characteristics and high hole mobility. Quinoxaline is thought to be a acceptor unit due to the electron withdrawing properties of the two imine nitrogen atoms. In this work, we synthesized and characterized D-A polymers with conjugated side group by Suzuki coupling reaction. We investigated the physical, optical, electrochemical and photovoltaic properties. |
