, the bridging group B, and the polycyclic core Cor
2
form a molecular system selected from the list comprising donor-bridge-acceptor-bridge-donor and acceptor-bridge-donor-bridge-acceptor in which a dissociation of excited electron-hole pairs is carried out. A solution of the organic compound or its salt forms a solid photovoltaic layer on a substrate.
