The present invention relates to an organic colorant corresponding to one of the following structures (I) or (II):
eD-pi-conjugated chromophore-L-A (I)
A-L-pi-conjugated chromophore-eD (II)
in which eD represents an electron donor segment; L represents a covalent bond or a spacer segment; A represents an electron attractor segment able to form a covalent bond with a semi-conductor; the pi-conjugated chromophore comprising at least two aromatic rings, at least one of which is a thiophene, selenophene or furan type ring. The present invention relates to the use thereof as photosensitizer in a photovoltaic device and said photovoltaic device.
Disclosed are an organic dye having a specific structure, a photoelectric conversion material containing the dye, a semiconductor electrode formed of a substrate having an electrically conductive surface, a semiconductor layer coated on the electrically conductive surface and the above dye adsorbed on the surface, and a photoelectric conversion device to which the above dye is applied.
The present invention uses the above dye and can therefore provide a photoelectric conversion device excellent in photoelectric conversion efficiency, and the photoelectric conversion device is suitable for use in a solar cell or the like.
