Abstract:
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.
