In spite of its solidity, the oligomer electrolyte has high ionic diffusion and good permeability into the nanopores of a TiO2 electrode. The electron diffusion coefficient and lifetime in a photoelectrocle are largely affected by the adsorptive interaction between cations and the TiO2 surface. The energy-conversion efficiency of DSSCS using the oligomer electrolyte is greater than 4.5%. Long-term storage at room temperature demonstrates that the stability of the oligomer electrolyte system is superior to that of a volatile solvent electrolyte. (C) 2008 Elsevier B.V.
