| 英文摘要 | The selection of sensitizer and its existence in the blend films are important to the performance of all-polymer ternary solar cells. herein, all-polymer ternary solar cell devices, which used poly[4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b'] dithiophene-alt-3-fluorothieno[3,4-b]thiophene-2-carboxy-late] (ptb7-th) as donor, poly[[n,n-bis (2-octyldodecyl)-napthalene-1,4,5,8-bis(dicarboximide) 22,6-diyl]-alt-5,5'-(2,2'-bithiophene)] (n2200) as acceptor and poly[n-900-hepta- decanyl-2,7-carbazole-alt-5,5-(40,70-di-2-thienyl-20,10,30-benzothiadiazole) (pcdtbt) as sensitizer, are successfully demonstrated. the intermolecular interaction between donor ptb7-th and sensitizer pcdtbt may lead to aggregation of ptb7-th which decreases domain sizes and enlarges d/a effective interface area. in addition, the pcdtbt molecules also extend light absorption and cascaded energy levels of the ternary blend system. as a result, with 15% pcdtbt we get a power conversion efficiency of 5.11%, almost 20% higher than control device due to more favored exciton dissociation and higher charge transport efficiency. this study reveals a promising way to achieve high efficiency all-polymer solar cells using a low-band gap polymer pcdtbt.
