Cathodically electrosynthesized TiO 2 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.
