Title:
PHOTOELECTRIC CONVERSION ELEMENT, METHOD FOR MANUFACTURING PHOTOELECTRIC CONVERSION ELEMENT, AND POLYMER ELECTROLYTE SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2011/102423
Kind Code:
A1
Abstract:
Disclosed is a low-cost photoelectric conversion element, which does not use a transparent conductive substrate or titanium oxide, and wherein a metal layer is formed to have a nano structure and thus to have an increased surface area (effective area) as an electrode in order to improve the dye sensitization efficiency by increasing the amount of dye molecules adsorbed and fixed onto the metal layer. In addition, the photoelectric conversion element has increased photoelectric conversion efficiency due to a surface plasmon resonance (SPR) effect. Also disclosed are a method for manufacturing the photoelectric conversion element; and a polymer electrolyte solar cell using the photoelectric conversion element. Specifically disclosed is a photoelectric conversion element comprising a polymer electrolyte, a metal layer and dye molecules, which is characterized in that: the metal layer is in contact with the polymer electrolyte; the metal layer is formed on the surface of and/or inside the polymer electrolyte; and the dye molecules are adsorbed on the metal layer.
