TECHNOLOGY FOCUS - ELECTRONICS - Preferred Transducer: The optoelectric transducer further has a molecular thin film of acceptor property, provided between the electrodes. The molecular thin film consisting of fullerene is laminated on the organic dye thin film.Preferred Properties: Similarly, the work function of electrodes (2,3) is different from each other. The photoelectric current of the optoelectric transducer, when light is incident from the side of electrode (2) differs from the photoelectric current of the optoelectric transducer, when light is incident from the side of electrode (3). Preferably, the photoelectric current of the optoelectric transducer, when light is incident from the side of electrode (2) having less work function is larger than the photoelectric current of the optoelectric transducer, when light is incident from the side of electrode (3) having more work function. The product of permeability of organic dye thin film and electrode (2) is larger than the product of permeability of organic dye thin film and electrode (3), where the permeability is measured in a region in which the organic dye thin film has absorption at 400 nm or more. Similarly, the product of permeability of molecular thin film and electrode (2) is larger than the product of permeability of molecular thin film and electrode (3).Preferred Electrodes: The electrode (2) has transparency and the electrode (3) consists of platinum.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Film: The organic dye thin film has bis-azomethine dye of formula (I or II) as a main component. The film thickness of the organic dye thin film is 1200-1800 Angstrom .R = methyl, ethyl, hydroxyethyl, cyanoethyl, n-propyl, iso-propyl, n-butyl, 2-valeryl ethyl, 2-(butyryl-oxyethoxycarbonyl) ethyl or pyrrolidinyl group; andX = ethyl carbonyl amide, thiomethoxy, thio-n-butoxy, phenyl sulfonyl, methyl sulfonyl, chlorine, nitro, hydroxyl, ethoxy, cyano, acetamide, benzyloxy, biphenyl carboxyl, fluorine, methyl, pyridine carboxyl, bromine, methoxy or 9-ethyl carbazole-3-yl.
