Embodiment Construction

[0038] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] Such as figure 1 shown, and refer to Figure 2-5 , the method of the embodiment of the present invention includes the following steps:

[0040] S1. Using screen printing technology to print TiO 2 The nanoparticle paste is printed on the conductive substrate (preferably F-doped tin oxide conductive glass (FTO conductive glass 1)) used to prepare the working electrode, so that the TiO 2 The nanoparticle paste was printed as several isolated TiO 2 Rectangular sheet film (may be referred to as TiO 2 film). TiO on each conductive substrate 2 Leave a gap between the films (for figure 2 The space between the four films) for easy packaging.

[0041] Among them, befor...

Abstract

The invention is directed to the field of dye sensitization solar energy cell production technology and particularly relates to a vacuum automatic packaging method used for a dye sensitization solar energy cell. According to the method, a screen printing method is adopted to prepare a TiO2 film, automatic gluing equipment is employed to form a required figure and a procuring is carried out, electrolyte is dripped into the figure formed by the packaging glue with an automatic dripping apparatus, leveling and stitching are carried out in a vacuum atmosphere and finally the packaging process of the cell is completed. The invention is characterized by simple technology, high controllability on technological parameter, short packaging time, good packaging reliability and high yield. The thickness of the cell and the amount of electrolyte are controlled through doping a cushion in the liquid state glue and the working electrode and the counter electrode are separated. The invention can be used for the packaging of a high efficiency large acreage dye sensitization solar energy cell.

Description

technical field [0001] The invention belongs to the technical field of dye-sensitized solar cell production technology, and in particular relates to a vacuum automatic packaging method for dye-sensitized solar cells. Background technique [0002] With the increase of the global population in recent years, energy depletion and global pollution have become problems that cannot be ignored. As an inexhaustible renewable energy source, solar energy plays an irreplaceable and important role in the process of human beings seeking new energy sources. A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Because solar cells only consume sunlight, do not need moving parts, operate very reliably, and have no impact on the environment, they naturally become the most ideal energy source for human beings. [0003] The phenomenon of photoelectric conversion was first observed by French scientist Henri...
