Visible light-operated glucose-O2 biofuel cell consisting of chlorin-e6 metal complexes (MChl?e6, M = H2 and Zn) adsorbed on TiO2 coated onto Optical Transparent conductive glass Electrode (OTE) as an anode, platinum electrode as a cathode, and the solution containing glucose, Glucose Dehydrogenase and NAD+ as a fuel is studied. The cells using H2Chl-e6 and Zn Chl-e6 adsorbed on TiO2 coated OTEs are defined as Biofuel CellH2 and Biofuel CellZn. The closed-circuit photocurrent in Biofuel CellH2 and Biofuel CellZn are 0.067 ? 0.003 and 0.017 ? 0.007 mA cm−2, and the open-circuit photo voltages are 503 ? 10 and 559 ? 12 mV, respectively.
