A series of polyfluorene-based copolymers with pyrene units have been synthesized and characterized for use in polymer solar cells. Under optimized conditions, the polymers display PCEs for the PSCs in the range 1.99–3.37% under AM 1.5 illumination (100 mW cm−2). The PCEs of polymer solar cells are improved from 2.11% for devices prepared without pyrene to 3.37% for devices prepared with pyrene.
