Abstract: The present invention relates to a photoelectric conversion device sensitized by supporting a methine based dye represented by the following formula (1): (in the above formula, n represents an integer of 0 to 7; X and Y each represent a hydrogen atom, an optionally substituted aromatic residue, an optionally substituted aliphatic hydrocarbon residue and the like. In addition, X and Y may combine together to form an optionally substituted ring. A1, A2 and A3 represent each independently an optionally substituted aromatic residue, an optionally substituted aliphatic hydrocarbon residue and the like. In addition, when n is other than 0, a plural number of A1 and/or A2 and/or A3 may form an optionally substituted ring.

Abstract: A dye-sensitized solar cell module comprising dye-sensitized solar cells arranged on a flat surface. Each dye-sensitized solar cell comprises a first substrate on which a first conductive layer having a photoelectric conversion layer forming part and an extension part is provided, a second substrate as the counter electrode on which a second conductive layer having a photoelectric conversion layer provided on the photoelectric conversion layer forming part on the first conductive layer is provided, a charge transfer layer contact part and an extension part, a third conductive layer provided on the extension part of the first and/or the extension part of the second conductive layer, a partition wall separating the dye-sensitized solar cell from an adjacent dye-sensitized solar cell, and a charge transfer layer. Part or whole of the partition wall contains conductive particles having conductive layers on their surfaces.

Abstract: Disclosed is a solar cell characterized by using in combination at least two or more different photoelectric converters for specific wavelength ranges, each of which photoelectric converters is obtained by loading a thin film of oxide semiconductor particles formed on a substrate with a dye having a maximum absorption wavelength in a specific wavelength range or a salt of the dye.
