Polyoxometalate-TiO(2) composites have been successfully introduced into the photoanode of dye-sensitized solar cells to reduce recombination electrons, which results in a longer electron lifetime. The performance with polyoxometalate-modified is better than cell pure P25 photoanode. effect polyoxometalate was studied by electrochemical impedance spectroscopy and open-circuit voltage decay measurement. show that lifetime becomes following an increase amount polyoxometalate.
