The new visible-light operated CO2-glucose biofuel cell consisting of chlorin-e6immobilized on TiO2thin layer film onto optical transparent conductive glass electrode (OTE) as an anode, formate dehydrogenase (FDH) and viologen with long alkyl chain co-immobilized OTE as a cathode, and the solution containing glucose, glucose dehydrogenase (GDH) and NAD+as a fuel was developed. The short-circuit photocurrent and the open-circuit photovoltage of this cell are 37 μA.cm-2and 390 mV, respectively. The maximum power is estimated to be 57 μW.cm-2. The overall photoenergy conversion efficiency is estimated to be 0.057%. After 2 h irradiation to this cell, 0.65 μmol of formic acid was produced. During irradiation, the photocurrent was constant value of 32 ± 10 μA.cm-2in the cell. Thus, CO2reduces and formic acid produces while generating electricity with visible light irradiation to this biofuel cell.
