A high molecular weight donor–acceptor conjugated polymer is synthesized using the Suzuki polycondensation method. Using this polymer, a single‐junction bulk‐heterojunction solar cell is fabricated giving a power conversion efficiency of 9.4% using a fullerene‐modified ZnO interlayer at the cathode contact.
