Solution-processable organic photovoltaic cells (OPVs) have attracted considerable interest.Over the past twenty years, fullerene and its derivatives have been predominately used as the electron acceptor materials to fabricate OPV devices.In recent few years, non-fullerene organic photovoltaic cells (NF-OPVs), consisting of polymers as the donors and the non-fullerene (NF) materials as the acceptors, have been developed rapidly, and the highest power conversion efficiencies of NF-OPVs exceed those of fullerene-based OPVs.In these NF-OPVs, both polymeric donor materials and NF acceptors play critical roles in achieving outstanding efficiencies, and hence, the molecular design of the polymer donors has been deemed a very important topic of research in the field.In this review, we will present an introduction of the specific requirements for polymer donors in NF-OPVs and summarize the recent progress related to polymer donors for the applications in highly efficient NF-OPVs.
