Abstract:
The present invention concerns an organic dye comprising a photochromic entity, a segment -eD representing an electron donor segment and a segment -L-A with -L- representing a covalent bond or a spacer segment and particularly a pi-conjugated spacer segment, and -A representing an electron attractor segment able to form a covalent bond with a semi-conductor. The present invention concerns the use thereof as photosensitizer in a photovoltaic device and said photovoltaic device.
