Two D-π-A conjugated molecules, and , were developed through facile synthetic approaches for dye-sensitized solar cells. The investigation of the photophysical properties of and both in dilute solutions and in thin films indicates that their absorption exhibits a wide coverage of the solar spectrum. The absorption features for and commence at about 710 nm in solution, and at about 800 nm in the solid state. The absorption maxima (λmax) for both and on TiO2 film are almost the same as those in dilute solution. Their HOMOs and LUMOs were found to partly overlap at the center of these dyes, which guarantees appreciable interactions between the donors and acceptors. The investigation of the performance of dye-sensitized solar cells fabricated from and indicated that the power-conversion efficiencies are 6.04 % and 4.68 %, respectively, which could be comparable with the normal sensitizer N3. BzTMCA showed lower incident photon-to-electron conversion efficiency (IPCE) and Jsc values relative to , which is probably because of the weaker driving force of dye regeneration and electron injection process of . The IPCE responsive area reached nearly 800 nm, which provides great potential for further improvement of the photocurrent density and power-conversion efficiency. Our investigations demonstrate that both dyes and could be promising candidates for dye-sensitized solar cells.
