中文摘要the effect of solvent mixtures on the morphologies of poly[n-9'-hepta-decanyl-2,7-carbazole-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)] (pcdtbt):[6,6]-phenyl c-71-butyric acid methyl ester (pc71bm) blend films is investigated. 1,2,4-trichlorobenzene (tcb) which is a good solvent for pcdtbt is selected to mix with chloroform (cf), chlorobenzene (cb) and o-dichlorobenzene (odcb) for tuning the morphology of the pcdtbt:pc71bm blend. it is found that formation of nanoscale phase separation with a fibrillar pcdtbt nanostructure of pcdtbt:pc71bm blend which is favorable for exciton separation and charge carrier transport is strongly dependent on the solubility parameters of the solvent mixtures. a clearly defined nanoscale phase separation of the pcdtbt:pc71bm blend can be obtained with tcb:cf mixture. the resulted morphology is similar to that produced with sole dcb solvent that is currently the best solvent for pcdtbt:pc71bm blend solar cells. moreover, the tcb:cf mixture demonstrates better solubility and processibility for pcdtbt:pc71bm blend and allows us to prepare thick active layer that is required in large-area roll-to-roll process. the polymer solar cells with 250 nm- thick active layer are fabricated by using tcb:cf solvent mixture and the power conversion efficiency of the devices reaches 6.45%. a highest short-circuit current of 13.6 ma/cm(2) is achieved due to enhanced optical absorption of thick active layer.
