Abstract: 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 Cell_H2 and Biofuel Cell_Zn. The closed-circuit photocurrent in Biofuel Cell_H2 and Biofuel Cell_Zn 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.
