A photovoltaic electroluminescent cell comprises a first electrode and a second electrode separated by dye linked block polymer molecule containing an n-type semiconductor polymer block linked via a light absorbing monomeric dye moiety to a p-type semiconductor polymer block the two polymer blocks being phase separated into distinct layers. The n-type semiconductor polymer block and the p-type semiconductor polymer block are each independently formed from selected polymers formed from terphenylenevinylene, polyaniline, polythiopene, poly (2-vinyl-pyridine), poly(NÂvinylcarbazole), poly-acetylene, poly (p-phenylenevinylene), polym-phenylene, poly-p-phenylene, poly-2,6-pyridine, or polypyrrole monomer, said polymers being substituted with electron withdrawing substituents in the case of the n-type polymer block and with electron donating substituents in the case of the p-type polymer block. |
