    • In a ball-milling apparatus was placed 1.3 g of TiO2 (Degussa P-25, 80% anatase, 20% rutile, To this was added deionized water (1.86 mL) in 6 portions and the mixture was ground and mixed at ambient temperature at 300 rpm for 10 min every after the addition. Then, the mixture was further mixed with 80 mg of PEG and 3-5 drops of nitric acid by ball-milling at 300 rpm for 2-3 h to give a TiO2 slurry. The TiO2 (5 × 5mm 2) layer was prepared on a FTO glass plate by casting the slurry, and the plate was sintered at 500 °C for 30 min. The TiO2-coated FTO glass plate was immersed in a chloroform solution of a polymer with or without irradiation in an argon atmosphere. After being washed with chloroform several times until the chloroform became colorless, the plate was air-dried at room temperature. Finally, a DSSC was fabricated with a thin liquid layer of an acetonitrile solution containing LiI (0.5 M)/I2 0.05 M
    • 2/FTO and Pt counter electrodes. The DSSC thus prepared was irradiated with a monochromatic light from the FTO side and the photocurrent was monitored as a function of wavelength by a digital electrometer (Advantest TR-8652).
