Abstract:
PROBLEM TO BE SOLVED: To provide a photoconductor which can prevent the carriers excited by light from disappearing by recombination while enhancing photoelectric conversion efficiency, and to provide a photoelectric conversion element using the photoconductor.SOLUTION: The photoconductor is formed of a composite of a conductive polymer and/or a polymer semiconductor 11, and one or a plurality of proteins 12 containing at least one dye 12a having a long life excited state. The dye 12a becomes a luminescence center. The conductive polymer and/or a polymer semiconductor 11 is formed in network. The conductive polymer and/or a polymer semiconductor 11 and the protein 12 are bonded by non-covalent bond or covalent bond. A photoelectric conversion element is configured by connecting first and second electrodes electrically to different parts of the conductive polymer and/or a polymer semiconductor 11 in network of the photoconductor.
Abstract:
PROBLEM TO BE SOLVED: To provide a novel protein which has extremely high stability to the irradiation with light and has a long-lasting photoelectric conversion function, and also to provide a protein photoelectric conversion element which is stably used over a long period of time using the same. SOLUTION: Iron, which is a metal located at the center of a heme of horse heart cytochrome c, is substituted by tin to produce tin-substituted horse heart cytochrome c. Iron, which is a metal located at the center of a heme of bovine heart cytochrome c, is substituted by tin to produce tin-substituted bovine heart cytochrome c. A protein 22 comprising the tin-substituted horse heart cytochrome c or the tin-substituted bovine heart cytochrome c is immobilized on an electrode 21 to produce a protein-immobilized electrode. A protein photoelectric conversion element is formed by using the protein-immobilized electrode. COPYRIGHT: (C)2011,JPO&INPIT
