摘要：

We synthesized three metal-free organic dyes (H11-H13) consisting of a 3,6-disubstituted carbazole, benzothiadiazole, and cyanoacrylic acid. All the dyes exhibited high molar extinction coefficients and suitable energy levels for electron transfer from the electrolyte to the TiO2 nanoparticles. Under standard AM 1.5G solar irradiation, the device using dye H13 with co-adsorbed chenodeoxycholic acid (CDCA) displayed the best performance: an open-circuit voltage (V-oc) of 0.71 V, a short-circuit current density (J(sc)) of 12.69 mA cm(-2), a fill factor (FF) of 0.71, and a power conversion efficiency (PCE) of 6.32%. The PCE was similar to 79% of that for commercially available N719 cells (8.02%) under the same conditions. (C) 2013 Elsevier Ltd. All rights reserved.
