| 英文摘要 | A novel oligothiophene-cyanoacrylic acid photosensitizer with two triphenylamine side chains (7T-2TPA) is designed and synthesized for dye-sensitized solar cells. 7T-2TPA exhibits broad (250-600 nm) and strong absorption (epsilon = 5.0 x 10(4) L mol(-1) cm(-1) at 496 nm). The optical band gap (E-g) is estimated from the onset absorption edge to be 2.07 eV. The oxidation potential E-ox and reduction potential E-red vs NHE of the dye is 0.93 and -1.14 V. respectively. Dye-sensitized solar cell (DSSC) based on 7T-2TPA exhibits an open-circuit voltage (V-oc) of 724 mV, a short-circuit current density (J(sc)) of 16.28 mA cm(-2), a fill factor (FF) of 0.684 and a power conversion efficiency of 8.06%. The efficiency of 8.06% is similar to that for widely used N719-based cell fabricated and measured under the same conditions. (C) 2012 Elsevier B.V. All rights reserved. |
