Abstract

A difluorobenzoxadiazole building block is synthesized and utilized to construct a conjugated polymer leading to high-performance thick-film polymer solar cells with a V(OC) of 0.88 V and a power conversion efficiency of 9.4%. This new building block can be used in many possible polymer structures for various organic electro-nic applications.

Keywords: conjugated polymer; difluorobenzoxadiazole; open-circuit voltage; polymer solar cells.
