ELECTRODE FOR SOLAR CELL, MANUFACTURING METHOD THEREFOR, AND SOLAR CELL PROVIDED WITH ELECTRODE

摘要

The present invention provides an electrode 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 for a solar cell is provided with: a substrate that has a conductive section on at least the surface thereof; and a conductive polymer layer that is laminated on the conductive section of the substrate. The conductive polymer layer includes: a polymer configured from at least one type of monomer selected from the group consisting of thiophene having a substituent in the third position and fourth position; and an anion generated, as a dopant to the polymer, from at least one type of compound that is a non-sulfonic acid organic compound, with the molecular weight of the anion thereof being at least 200. Additionally, the density of the conductive polymer layer is in the range of 1.15 to 1.80 g/cm3. The abovementioned dense conductive polymer layer including a supporting electrolyte anion as a dopant exhibits excellent heat resistance.
