dc.description.abstract | A series of coumarin dyes containing a low-band-gap chromophore of ethylenedioxythiophene (EDOT), which comprises a coumarin moiety as the electron donor and a cyanoacrylic acid moiety as electron acceptor in D-pi-A chromophores, were developed for use in dye-sensitised solar cells (DSSCs). These coumarin dyes have been used to fabricate DSSCs using I-/I-3(-) liquid electrolytes and their device performances were compared with that of NKX-2677 as a standard dye. Even though HKK-CM2 and HKK-CM3 have more extended aromatic units than HKK-CM1, the degree of pi-conjugation in HKK-CM2 and HKK-CM3 is less efficient than that of HKK-CM1, due to the relatively larger torsion angle between the plane of the donor and that of the acceptor. It is also in a good agreement with Density Functional Theory (DFT) calculations. As a result, a solar cell based on HKK-CM1 sensitiser shows better photovoltaic performance with J(SC) 0114.2 mA cm(-2), V-OC of 0.60 V, and a fill factor of 0.70, corresponding to an overall conversion efficiency eta of 6.07% under the standard AM 1.5 irradiation, than HKK-CM2 and HKK-CM3-based solar cells.
