Coumarin dyes with D-low band gap chromophore (ethylenedioxythiophene)-A containing coumarin moiety as the electron donor and cyanoacetic acid moiety as electron acceptor were developed for use in dye-sensitized solar cell. Their chemical structures were characterized by 1H-NMR, FT-IR, UV-vis absorption, and EI-mass spectroscopies. Their electrochemical properties were studied by cyclic voltammetry measurement. These coumarin derivatives have been used to fabricate dye-sensitized solar cells based on I-/I2 liquid electrolytes as dye sensitizers and their device performances were evaluated by comparing with that of Ru dye and NKX-2677 dye. |
