Manipulated photocurrent generation from pigment-exchanged photosynthetic proteins adsorbed to nanostructured WO3-TiO2 electrodes

A novel photoelectrode (PE) consisting of the pigment-exchanged photosynthetic reaction center (RC) trapped on the mesoporous WO3 TiO2 film was fabricated to facilitate biophotoelectric conversion by manipulating the excitation relaxation of the proteins.
