Abstract

Four novel D-D-π-A type organic dyes (DWH1-DWH4) were designed and synthesized, in which 3,6-bis(thiophene or hexylthiophene)-disubstituted carbazole moieties were used as the electron donor, bithiophene units or their derivatives as the π-conjugated bridge, and a cyanoacrylic acid group as the electron acceptor. The photovoltaic performance data indicate that the tuning of the J_sc and V_oc values can be conveniently accomplished by incorporation of long alkyl chains into sensitizer, which not only improves the molar extinction coefficients of the absorption and enhances the solubility but also increases the electron lifetime by leading to an effective spatial separation of the charges.
