摘要： Disclosed is an electrode body for a solar cell, which is capable of being used as a component of both an organic thin-film solar cell and a dye-sensitized solar cell, and has excellent heat resistance. This electrode body for a solar cell is provided with a substrate with a conductive part at least on the surface and a conductive polymer layer located on the conductive part of the substrate, in which the conductive polymer layer includes: a polymer which is obtained by polymerizing a monomer selected from the group consisting of 3,4-disubstituted thiophenes; and an anion as a dopant to the polymer generated from at least one organic non-sulfonate compound having an anion with the molecular weight of 200 or more. Since the anion of the organic non-sulfonate compound is included as a dopant in the conductive polymer layer, the heat resistance of the conductive polymer layer is improved.

摘要： Disclosed is a polymerization fluid for electropolymerization which exhibits a reduced environmental burden and excellent economic efficiency and which can yield a conductive polymer film that has high conductivity and that is dense and highly transparent. The polymerization fluid includes at least one monomer selected from the group consisting of 3,4-disubstituted thiophenes which is dispersed as oil drops in surfactant-free water, and the polymerization fluid is transparent. The polymerization fluid can be produced by a method which includes: an addition step of adding the monomer to surfactant-free water to prepare a phase separation fluid where water and the monomer are phase-separated; a first dispersion step of irradiating the phase separation fluid with ultrasonic waves to make the monomer dispersed in the form of oil drops and thus prepare an opaque dispersion, and a second dispersion step of irradiating the opaque dispersion with ultrasonic waves having a frequency higher than that of the ultrasonic waves used in the first dispersion step to reduce the mean size of the oil drops of the monomer and thus prepare a transparent dispersion.

摘要： A solid electrolytic capacitor is impregnated with a conductive polymer dispersion solution comprising sorbitol. In the capacitor, the hydroxyl group of sorbitol acts as the oxygen source necessary for the anodic oxidation of anodic oxide film when voltage is applied to the solid electrolytic capacitor. Consequently, the oxide film is repaired and withstand voltage property is improved, which is thought to be due to the anodic oxidation that repairs the damage on the oxide film. Superior electric capacitance can further be attained by specifying the sorbitol content in the dispersion solution to be at 60-90 wt %.
