Unlocking the dynamics of the evolution of the excited state at the complicated titania/dye/electrolyte interface in organic dye-sensitized solar cells is crucial to provide a basis for the rational design of low-energy-gap organic photosensitizers. By constructing two organic donor-acceptor dyes composed of benzothiadiazole-benzoic acid (BTBA) and pyridothiadiazole-benzoic acid (PTBA) as electron acceptors, we have identified the images of multiple-step relaxations of the excited state and multiple-state electron injections at the titania/dye/electrolyte interface using ultrafast transient absorption spectroscopic measurements in conjunction with theoretical simulations. Density functional theory and time-dependent density functional theory calculations indicate that there should be torsion-induced excited state relaxations from an optically generated ?hot? excited state to the equilibrium excited state characteristic of a more planar conjugated backbone and a quinonoid structure for dye molecules on the titania surface, suggesting the probable presence of multiple-state electron injections at the titania/dye/electrolyte interface. In virtue of a target analysis of femtosecond transient absorption spectra, we have found that the dye with PTBA features a much lower overall electron injection yield with respect to the dye with BTBA owing to the sluggish electron injection and short lifetime of the excited state, accounting for a lower maximum of external quantum efficiencies of the device made from the dye with PTBA as an acceptor.
