| 英文摘要 | three low bandgap conjugated polymers based on 7-fluorinated isoindigo (iid1f) and dithieno[3,2-b;6,7-b]carbazole (dtc), i.e., poly[n-dodecyldithieno[3,2-b;6,7-b]carbazole-alt-7-fluoro-n,n-di(2-octyldodecyl)isoindigo] (p1), poly[n-dodecyldithieno[3,2-b;6,7-b] carbazole-alt-7-fluoro-n,n-di(3-octyltridecyl)isoindigo] (p2) and poly[n-dodecyldithieno[3,2-b;6,7-b] carbazole-alt-7-fluoro-n,n-di(4-octyltetradecyl)isoindigo] (p3), were synthesized. all three polymers are soluble in non-chlorinated solvent o-xylene owing to regio-random distribution of f-atoms along the conjugated backbone. the position of the alkyl-branching point has a negligible influence on energy levels and absorption spectra of the polymers, but has a small effect on their charge transport properties. bulk heterojunction (bhj) polymer solar cells (pscs) of the polymers were fabricated with phenyl-c-61-butyric acid methyl ester (pc61bm) as an electron acceptor. when o-xylene was used as a solvent, all three polymers delivered power conversion efficiencies (pces) above 7%. p2 exhibited the best device performance with a pce of 7.5%. the devices processed with o-xylene showed higher device efficiency than those fabricated with o-dichlorobenzene (o-dcb) since the films of polymer: pc61bm blends prepared with o-xylene exhibited better morphology and higher and more balanced charge-carrier mobilities, leading to less recombination loss and higher fill factor (ff). |
