A highly crystalline and low bandgap donor polymer, EI-PFDTBT, is developed by inserting ethylene bridging units to ensure a coplanar configuration between the side chains and the main chain. Polymer solar cells based on the EI-PFDTBT and PC71BM blends spincoated at elevated temperatures exhibit a power conversion efficiency of 5.1%.
