Problems solved by technology

However, in the manufacture of large-area battery modules, when the titanium dioxide film layer is treated with a titanium tetrachloride solution, the metal grid electrode will be severely corroded. Even if the inorganic insulating layer is prepared on the metal grid electrode, it will be corroded by the solution, resulting in electrolyte The solution penetrates the insulating layer and corrodes the metal gate electrode

Abstract

The invention discloses a method for preparing a dye-sensitized solar cell module. In order to adopt the modification technology of titanium tetrachloride, the method comprises the following steps of: manufacturing an insulating layer by using an organic material to protect a silver grid electrode, then putting the silver grid electrode into titanium tetrachloride solution to perform soaking treatment under the condition of ensuring that the silver grid electrode is not corroded during treatment, fully burning the organic insulating layer after the soaking treatment is finished, and manufacturing an inorganic insulating layer on the silver grid electrode so as to ensure long-term stability of the cell module and improve the photoelectric conversion efficiency of the series / parallel large-area cell module.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a preparation method of a dye-sensitized solar cell module. Background technique [0002] Dye-sensitized solar cells have a simple manufacturing process and relatively low price. They have potentially high photoelectric conversion efficiency, and are likely to replace traditional silicon-based solar cells and become the dominant solar cells in the future. Currently, under standard conditions, the energy conversion efficiency of dye-sensitized solar cells has exceeded 11%. [0003] The substrates used in battery production are generally glass substrates or other flexible transparent materials with transparent conductive films such as indium-doped tin oxide (ITO) or fluorine-doped tin oxide (FTO). However, ITO or FTO has a larger square resistance than metals such as silver and copper. When it is applied to the production of dye-sensitized solar cells, especially for large-are...
