Abstract

The invention belongs to the technical field of solar cells, and relates to a method for preparing a dye-sensitized solar cell module. The invention utilizes flat screen printing and thermal sintering technology to prepare various structural layers of the dye-sensitized solar cell module, and then encapsulates the structural layers; the various structural layers are as follows: a photo-anode consists of a transparent glass substrate, a transparent conductive film, a nanometer porous semiconductor film, a dye adsorption layer, a conductive silver grate layer, an insulating medium protective layer and an insulating medium encapsulation layer; and a cathode consists of a transparent glass substrate, a transparent conductive layer, a platinum catalysis layer, a conductive silver grate layer, an insulating medium protective layer, an insulating medium encapsulation layer, an ultraviolet curing layer and a sealing substrate; and electrolyte is poured between the photo-anode and the cathode through a cathode hole. The method has mature technology, low cost, simplicity, controllability, and easy operation, and can realize mass-production preparation of dye-sensitized solar cell modules with large areas and various internal structures.

Description

Technical field [0001] The invention belongs to the technical field of solar cells and relates to a method for preparing a dye-sensitized solar cell module. Background technique [0002] Compared with silicon solar cells, dye-sensitized solar cells have attracted worldwide attention because of their simplicity and low cost. They are considered to be the next generation solar cells that can replace silicon solar cells. The dye-sensitized solar cell includes a photoanode, an electrolyte and a cathode; among them, the photoanode and the cathode are stacked relative to each other and sealed around to form a closed cavity, which is filled with electrolyte. [0003] At present, the preparation of dye-sensitized solar cells has become one of the focuses of attention. For the industrialization of dye-sensitized solar cells, it is of great significance to achieve the structural design, manufacturing and assembly of cells with one method or process. Currently, although a variety of ...
