Photoelectrochemical biofuel cells based on H2-mesoporphyrin IX or Zn-mesoporphyrin IX sensitizer on titanium dioxide film electrode

► A new two-compartment photoelectrochemical biofuel cell is fabricated. ► This cell is based on H2-mesoporphyrin IX or Zn-mesoporphyrin IX sensitizer. ► H2-mesoporphyrin IX shows a better performance than Zn-mesoporphyrin IX.
