Abstract

The invention relates to a method for preparing an energy storage electrode of a dye-sensitized solar battery, comprising the following steps of: adding 5%-15% by mass of poly-p-styrene sulfonate or the water solution of hydrochloric acid to a conducting polymer and mixing, wherein the additon is preferably to reach the effect of immersing the conducting polymer; soaking, drying, and then adding one or the mixture of some of alcohol, terpineol, isopropanol or naphthol to the well-mixed conducting polymer, wherein the mass ratio of the well-mixed conducting polymer is 20%-50% in a system; dripping a polytetrafluoroethylene bonder, ultrasonically oscillating for 30 min-60 min, and then statically placing for later use; and fixing a Pt slice by using an adhesive tape, dripping the solution on the Pt slice by using a dropper, uniformly coating and dispersing, then taking out after drying for 10 min-30 min at 80 DEG C, and repeatedly the operations to obtain the energy storage electrode with the coating thickness of 15-100 mu m. By adopting the method, the dye-sensitized solar battery can store energy under the condition of light irradiation without influencing the normal work, and release the energy in the dark, thereby realizing the energy storage process of the dye-sensitized solar battery.

Description

technical field [0001] The invention relates to the technical field of conductive polymers and novel solar cells, and belongs to the technical fields of new materials and new energy sources. Background technique [0002] As a new type of solar cell, dye-sensitized solar cells have attracted widespread attention because of their simple preparation process, high photoelectric conversion efficiency, and low manufacturing cost. However, in the absence of light, dye-sensitized solar cells cannot work normally. Therefore, the development of energy storage dye-sensitized solar cells has become one of the hotspots, but there is no related report on the preparation method of energy storage electrodes of dye-sensitized solar cells under the two-electrode system. Contents of the invention [0003] The object of the present invention is to provide a method for preparing a counter electrode of a dye-sensitized solar cell capable of storing energy, so that the cell can work normally wh...
