| 英文摘要 | A new ultra-narrow bandgap and 2D-conjugated D-A copolymer, PBDTT-TIID, based on bithienyl-benzodithiophene (BDTT) donor unit and (E)-4,4'-bis(2-ethylhexyl)-[6,6'-bithieno[3,2-b]pyrrolylidene]5,5'(4H,4'H)-dione (TIID) acceptor unit was designed and synthesized for the application as donor material in polymer solar cells (PSCs). The polymer demonstrates two absorption peaks at around 450 nm and 900 nm respectively, and possesses a very narrow bandgap (E-g) of 1.17 eV and a higher hole mobility of 4.48 x 10(-3) cm(2)/V s. The PSCs based on PBDTT-TIID:PC71BM (1:1, w/w) demonstrate a higher V-oc of 0.59 V even though the polymer has a very narrow E-g of 1.17 eV, which is corresponding to a low energy loss (E-loss) of 0.58 eV. In addition, an optimal PCE of 2.40% was achieved with 1% DIO as additive. (C) 2016 Elsevier B.V. All rights reserved. |
