  • PHOTOELECTROCHEMICAL CELL AND ENERGY SYSTEM USING SAME
    Publication number: 20120156578
    Abstract: A photoelectrochemical cell (100) includes: a semiconductor electrode (120) including a conductor (121) and semiconductor layers (122, 123) disposed on the conductor (121); a counter electrode (130) connected electrically to the conductor (121); an electrolyte (140) in contact with surfaces of the semiconductor layer (123) and the counter electrode (130); and a container (110) accommodating the semiconductor electrode (120), the counter electrode (130) and the electrolyte (140). A band edge level ECS of a conduction band, a band edge level EVS of a valence band, and a Fermi level EFS in a surface near-field region of the semiconductor layer, and a band edge level ECJ of a conduction band, a band edge level EVJ of a valence band, and a Fermi level EFJ in a junction plane near-field region of the semiconductor layer with the conductor satisfy, relative to a vacuum level, ECS-EFS>ECJ-EFJ, EFS-EVS<EFJ-EVJ, ECJ>?4.44 eV, and EVS<?5.67 eV.

  • PHOTOELECTROCHEMICAL CELL AND ENERGY SYSTEM USING THE SAME
    Publication number: 20120028141
    Abstract: A photoelectrochemical cell (100) includes: a semiconductor electrode (120) including a substrate (121), a first n-type semiconductor layer (122) disposed on the substrate (121), and a second n-type semiconductor layer (123) and a conductor (124) disposed apart from each other on the first n-type semiconductor layer (122); a counter electrode (130) connected electrically to the conductor (124); an electrolyte (140) in contact with surfaces of the second n-type semiconductor layer (123) and the counter electrode (130); and a container (110) accommodating the semiconductor electrode (120), the counter electrode (130) and the electrolyte (140).
