Embodiment

[0252] Hereinafter, the present invention will be described in more detail based on examples, but the present invention should not be interpreted as being limited thereto.

Synthetic example

[0254] Intermediate D4-5 was synthesized using the route shown in Scheme 1.

[0255] [chem 22]

[0256]

[0257] Dye 4 was synthesized in the same manner as in the literature "Chem.Commun.", 2009, 5844. using intermediate D4-5.

[0258] The dyes 1 to 3 and the dyes 5 to 11 were synthesized in the same manner.

Embodiment 1

[0260] Various pastes for forming the semiconductor layer or the light scattering layer of the semiconductor electrode constituting the photoelectrode are prepared, and the dye-sensitized solar cell is fabricated using the paste.

[0261] [Preparation of paste]

Abstract

The invention provides a photoelectric conversion element, a photoelectrochemical cell and a pigment used therein. A photoelectric conversion element, which is a photoelectric conversion element having a laminated structure in which a photoreceptor layer having a layer of semiconductor fine particles adsorbed with a pigment, a charge moving body layer, and an opposing The layered structure of electrodes, the photoelectric conversion element is characterized in that a metal complex dye represented by the following formula (1) is used as the dye. ML1L2X(1) [wherein, M represents a transition metal selected from ruthenium, osmium, iron, rhenium, and technetium. X represents NCS-, Cl-, Br-, I-, CN-, NCO-, H2O, or NCN2-. L1 represents a specific 3-dentate ligand, and L2 represents a specific 2-dentate ligand].

Description

technical field [0001] The invention relates to a photoelectric conversion element, a photoelectrochemical cell, and a pigment used therein. Background technique [0002] Photoelectric conversion elements are used in various photosensors, copiers, solar cells, and the like. The photoelectric conversion element has been put into practical use in various forms such as a photoelectric conversion element using a metal, a photoelectric conversion element using a semiconductor, a photoelectric conversion element using an organic pigment or a pigment, or a combination of these photoelectric conversion elements. Among them, a solar cell utilizing non-exhaustive solar energy does not require fuel, and its full-scale practical application is largely expected as a photoelectric conversion element utilizing inexhaustible clean energy. Among them, research and development of silicon-based solar cells has been conducted for a long time. Countries also have policy considerations to popul...
