The photoelectric conversion device described herein includes a working electrode having a dye-supported metal oxide electrode in which a dye is supported on a metal oxide layer. The dye includes a structure represented by general formula (I) The present invention relates to a photoelectric conversion device and a photoelectric conversion device dye, and a compound.Conventionally, dyes have been widely used in various technical fields. As one example, in the field of photoelectric conversion devices, for example, a dye having photosensitization action is used in the working electrode of a dye-sensitized solar cell.A dye-sensitized solar cell generally has an electrode having an oxide semiconductor as a support for a dye. Such a dye absorbs incident light and is excited, and this excited dye injects electrons into the support to perform photoelectric conversion. In this type of dye-sensitized solar cell, high energy conversion efficiency can be theoretically expected among organic solar cells. In addition, this type of dye-sensitized solar cell can be produced at lower cost than conventional solar cells using a silicon semiconductor, and therefore is considered to be very advantageous in terms of cost.On the other hand, as dyes used in photoelectric conversion devices, organic dyes, such as ruthenium complex dyes and cyanine dyes, are widely known. Particularly, cyanine dyes have relatively high stability, and can be easily synthesized, and therefore, various studies have been made.For example, Patent Document 1 discloses a cyanine dye that has a structure in which an indolenine skeleton is bonded to both ends of a methine chain skeleton, and further has a carboxylic acid group as an anchor group to be adsorbed on an oxide semiconductor electrode.In addition, Patent Document 2 discloses a composite dye in which a plurality of component dyes having different excitation levels from each other are chemically bonded to each other, thereby forming a linear or branched ...

This layer ( 21 ), normally a TCO, have limited conductivity, implying the use of current collector lines applied in a complex manner. The conductivity of the conductive layer ( 21 ) is increased by the application of a structure, in particular a grid, of thin conductive lines ( 22 ) inserted in grooves on the glass surface ( 23 ) or directly applied on this, followed by a TCO layer coating ( 21 ). This highly conductive grid ( 22 ) collects the electricity from the TCO layer ( 21 ) and directs it to the periphery of the cell. Both glass substrates are sealed by a process employing a precursor of glass surrounding the entire perimeter of the substrate. The glass precursor is heated to its melting point, by a laser, completely sealing the two substrates of the module.
