Five thieno[3,4-c]pyrrole-4,6-dione (TPD)-terthiophene copolymers, PHT, P1F3HT, P1F1HT, P3F1HT, and PFT, having 0, 25, 50, 75, and 100% of fluorine substituents on the center of terthiophene exhibit a progressive increase of open-circuit voltage (VOC), short-circuit current density (JSC), and hence a power conversion efficiency (PCE) up to 9.68% of PC61BM-blended copolymer photovoltaics, which is the highest PCE reported for TPD-based polymer solar cells with fullerene derivatives as the...

High efficiency of 10.7% achieved by novel isoindigo copolymers and fullerene-based thick (> 300 nm) photovoltaics with extended nano-fibrillar network and high face-on ratio of the copolymers Chin-Ti Chen, Song-Fu Liao, Chun-Fu Lu, Adane Desta Fenta, Chi-Yang Chao  and Wei-Fang Su Abstract Three D-A π-conjugated copolymers PnTIF (where n = 2, 4, or 6), composed of isoindigo electron acceptor unit and difluorinated bithiophene (BTF) electron donor unit, have been synthesized and characterized.
