TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: The light harvesting dye is not bonded to the electron acceptor by a chemical bond. The multicomponent blend is adapted to generate photocurrent in response to incident light across the entire solar spectrum. It generates a photocurrent in response to incident light within a predetermined wavelength range.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compound: The electron acceptor may be titanium dioxide.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The multicomponent blend contains the electron acceptor in a weight ratio of greater than 2 relative to the semiconductor polymer and the light harvesting dye. It contains the semiconductor polymer, the electron acceptor and the light harvesting dye(s) in a weight ration of 1:8:1, respectively. Preferred Compounds: The light harvesting dye is tetranitrogen macrocycles, tetrapyrollic macrocycles, phthalocyanines, metallated tetracyanoporphyrins, or preferably porphyrins with different Q-band absorption spectra from one another. It is methyl-2-cyano-3-(2'-(5',10',15',20'-tetraphenylporphyrinyl)) acrylate, methyl-2-cyano-3-(2'-(5',10',15',20'-tetraphenylporphyrinato zinc(II)yl)) acrylate, or a diprotonated bistriflate salt of methyl-2-cyano-3-(2'-(5',10',15',20'-tetraphenylporphyrinyl)) acrylate. The electron acceptor may be fullerene, fullerene derivative, pyrene, pyrene derivative, naphthimide, naphthimide derivative, viologen, viologen derivative, nicotinamide, nicotinamide derivative, 7,7',8,8'-tetracyanoquinodimethane, 7,7',8,8'-tetracyanoquinodimethane derivative, perylene, or perylene derivative. It is (6,6)-phenyl-C61-butyric acid methyl ester.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compound: The electron acceptor may be titanium dioxide.    TECHNOLOGY FOCUS - POLYMERS - Preferred Polymers: The semiconducting polymer may be a polymeric material containing extended pi-systems for charge conduction.
