A co-adsorbents modified nanocrystalline TiO₂ thin-film electrode was studied for application in dye-sensitized solar cells. The effects of di(3,3-dimethylbutyl) phosphoric acid and chenodeoxycholic acid modification on the flat band potential and the passivation of the TiO₂ thin-film electrode were investigated by determining the flat-band potential and undertaking electrochemical impedance spectroscopy (EIS). The results suggest that di(3,3-dimethylbutyl) phosphoric acid is more effective in passivating the TiO₂ film surface and in shifting the flat-band potential negatively. For the dye-sensitized solar cells, EIS measurements indicate that the use of di(3,3-dimethylbutyl) phosphoric acid as a co-adsorbent may be more effective in increasing the electronic lifetime and the open-circuit voltage of the device than chenodeoxycholic acid.
