Problems solved by technology

[0003] At present, the commonly used auxiliary electrode materials with high conductivity set on the conductive substrate are easily corroded by the electrolyte. Even if an inorganic insulating layer (commonly used dielectric material) is prepared on the auxiliary electrode, it can protect the electrode from electrolyte corrosion, but in titanium tetrachloride When the solution modifies the titanium dioxide film layer, the insulating layer protecting the auxiliary electrode is easily corroded by the titanium tetrachloride solution, resulting in the corrosion of the auxiliary electrode.

Abstract

The invention provides a method for preparing a dye-sensitized solar cell. The method comprises the following steps of: preparing a photo-anode conductive glass substrate printed with a silver gate electrode and a counter electrode conductive glass substrate; evaporating a transparent LaB6 layer on the silver gate electrode of the photo-anode conductive glass substrate; spraying a silane couplingagent layer on the photo-anode conductive glass substrate again; drying the silane coupling agent layer and printing a titanium dioxide thin film layer in a gap of the photo-anode silver gate electrode; sintering the photo-anode conductive glass substrate; placing the sintered photo-anode conductive glass substrate in prepared dye solution to dye-sensitize the titanium dioxide thin film layer to prepare a photo-anode; preparing an inorganic insulating layer on the counter electrode conductive glass substrate, printing a platinum electrode, and sintering the substrate to prepare a counter electrode; and finally butting the photo-anode and the counter electrode, pouring electrolyte and packaging. The method of the invention can protect the silver gate electrode from being corroded by solution of titanium tetrachloride and solution of electrolyte, so that the stability of a cell module is ensured.
