要約
(EN)
Provided is a lightweight dye-sensitized solar cell which is provided with a positive electrode that has excellent catalytic ability and heat resistance. A dye-sensitized solar cell according to the present invention is provided with: a negative electrode which has a semiconductor layer that contains a dye; an electrolyte layer which is laminated on the semiconductor layer of the negative electrode and contains an oxidizing species and a reducing species that form a pair with each other; and a positive electrode which is laminated on the electrolyte layer and has a conductive polymer layer that serves as a catalyst which converts the oxidizing species into the reducing species. The conductive polymer layer is formed on a tin-doped indium oxide conductive layer of a base, wherein the conductive layer is formed on a plastic film, and contains a polymer which is configured from a thiophene that has substituents at the 3-position and the 4-position and anions which are generated from a non-sulfonic acid-based organic compound and serve as a dopant for the polymer. In addition, the conductive polymer layer has a density within the range of 1.15-1.80 g/cm3. The surface of the conductive layer, said surface facing the conductive polymer layer, has a root mean square roughness of 5.0 nm or more.

L'invention concerne une cellule solaire sensibilisée par un colorant légère qui comporte une électrode positive dont la capacité catalytique et la résistance à la chaleur sont excellentes. Une cellule solaire sensibilisée par un colorant selon la présente invention comporte : une électrode négative qui comprend une couche semi-conductrice qui contient un colorant ; une couche d'électrolyte qui est stratifiée sur la couche semi-conductrice de l'électrode négative et contient une espèce oxydante et une espèce réductrice qui ensemble forment une paire ; et une électrode positive qui est stratifiée sur la couche d'électrolyte et qui a une couche conductrice polymère qui sert de catalyseur qui convertit l'espèce oxydante en l'espèce réductrice. La couche polymère conductrice est formée sur une couche conductrice d'oxyde d'indium dopée à l'étain d'une base, la couche conductrice étant formée sur une pellicule plastique, et contient un polymère qui est constitué d'un thiophène dont la position 3 et la position 4 comportent des substituants et des anions qui sont générés à partir d'un composé organique à base d'acide non sulfonique et qui servent de dopant pour le polymère. De plus, la couche polymère conductrice a une densité comprise entre 1,15 et 1,80 g/cm3. La rugosité moyenne quadratique de la surface de la couche conductrice, ladite surface faisant face à la couche polymère conductrice, est supérieure ou égale à 5,0 nm.
