A 4% efficient dye-sensitized solar cell fabricated from cathodically electrosynthesized composite titania films
Cathodically electrosynthesized TiO2 films (see Figure) containing occluded Degussa P-25 titania particles can yield short-circuit current densities as high as 10.5 mA cm(-2), an open-circuit photovoltage of 690 mV, a fill factor of 57.3 %, and a photovoltaic efficiency of 4.13 % under simulated air mass 1.5 (100 mW cm(-2)) sunlight in a dye-sensitized solar cell device.
