Abstract

The invention provides an organic conducting film layer, a manufacturing method of the organic conducting film layer, a dye-sensitized battery flexible photocathode containing the flexible organic conducting film layer and a dye-sensitized battery, and belongs to the technical field of solar battery. The problems that an existing organic conducting film layer and the dye-sensitized battery flexible photocathode manufactured by the organic conducting film layer are large in mass per unit, incapable of being bent and high in cost are solved. The organic conducting film layer comprises a metal conducting net used as a skeleton, and a transparent conducting polymer fixed on the metal conducting net. The organic conducting film layer has the advantages of being light in mass per unit (with the same thickness), having flexibility and being low in cost. Meanwhile, the conducting metal net is used as the skeleton, conductivity of the organic conducting film layer is strengthened, and sheet resistance of the organic conducting film layer is reduced. A piece of conducting glass of a platinum plating layer is replaced by the organic conducting film layer, and the quality and the cost of the photocathode on the unit area are both reduced by more than 50 percent.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a preparation method of an organic conductive film layer of a flexible photocathode of a dye-sensitized cell and a dye-sensitized cell. Background technique [0002] Due to the increasingly serious global energy crisis, human beings are eager to find a sustainable green energy source. As an inexhaustible natural energy source, solar energy has become one of the important choices for people. As a new type of battery, dye-sensitized batteries have the advantages of low cost, green environmental protection, and simple production compared with traditional batteries. [0003] Dye-sensitized cells are mainly composed of the following parts: conductive base layer, nano-TiO2 film layer, dye-sensitized layer, electrolyte and photocathode. Among them, conventional dye-sensitized cells mainly use platinum-coated conductive glass as the photocathode. Due to the nature of th...
