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 derived from at least one 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. Additionally, the density of the conductive polymer layer is in the range of 1.15 to 1.80 g/cm 3 . The dense conductive polymer layer including the anion as a dopant exhibits excellent heat resistance.

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.

The present invention provides a polarizable electrode for an electrical double layer capacitor which has good high-temperature storage characteristics and can prevent a decrease in electrostatic capacity and increase in internal resistance, and also provides an electrical double layer capacitor using the electrode. A polarizable electrode is formed by mixing Ketjen black, active charcoal and a polytetrafluoroethylene (PTFE) aqueous solution. An etched aluminum foil is used for the collector, and this etched aluminum foil is dipped in a phosphoric acid aqueous solution or an ammonium phosphate or other phosphate aqueous solution to thereby retain 15 to 115 mg/m 2 of phosphorus on the surface of the etched aluminum foil. The electrostatic capacity per unit area on the surface of this etched aluminum foil is 50 to 350 µF/cm 2 .

摘要:
A capacitor element (10) fabricated by winding an anode foil (1) and a cathode foil (2) via a separator (3) is impregnated with a 3,4-ethylenedioxythiophene and an oxidizing agent to form poly(ethylenedioxythiophene) by chemical polymerization. A nonwoven fabric composed chiefly of a synthetic fiber is used as a separator, enabling a solid electrolyte to be favorably formed without being reacted with the oxidizing agent. Preferably, the capacitor element is dipped in water at 80 to 100 DEG C for 1 to 20 minutes to dissolve and remove the binder in the separator in order to preclude adverse effects on the electric characteristics caused by the binder. The oxidizing agent is used at a concentration in excess of 40 % by weight with respect to the solvent, so that the degree of polymerization is high and a dense and homogeneous solid electrolytic layer is formed. To form the electrolytic layer, the capacitor element is impregnated with a monomer solution prepared by mixing 3,4-ethylenedioxythiophene and a volatile solvent at a volume ratio of 1:1 to 1:3. Then, the capacitor element is heat-treated and impregnated with a solution of oxidizing agent to form a dense and homogenous solid electrolytic layer.
摘要:
Feature quantities such as an area, a circumferential length, end points, the center of gravity, and a moment are extracted for each image area. When one of the pixel immediately preceding the detected pixel on the same line and the pixel that is on the immediately preceding line and right above the detected pixel belongs to a prescribed image area after a pixel having a prescribed density is detected in scanning one line, the area number of the image area is inherited. The processing is performed sequentially on the succeeding pixels to store resulting image data are stored in a line buffer. When consecutive pixels belong to respective image areas but have different area numbers after the scanning of the one line has completed, the image buffer is scanned in the reverse direction and the different area numbers are modified to the same number to store feature quantities for each image area.
