Packaging material and packaging method for dye sensitized solar cell

Abstract

The invention relates to a packaging material and a packaging method for a dye sensitized solar cell. The packaging material consists of the following components in percentage by weight: 70 to 95 percent of organic silicon gel and 5 to 30 percent of reinforced material, wherein the reinforced material is glass microspheres or polystyrene microspheres with particle size of 5 to 80 mu m. The packaging method comprises the following steps of: weighing 70 to 95 weight percent of organic silicon gel serving as a packaging body material; adding 5 to 30 weight percent of glass microspheres or polystyrene microspheres with particle size of 5 to 30 mu m into the organic silicon gel and blending the materials; printing the mixture onto a packaging side of the cell; and solidifying the whole cell at the temperature of between 20 and 60 DEG C for 12 to 72 hours after an upper substrate and a lower substrate of the cell are abutted so as to package the cell. The method of the invention has the advantages of simple operation and no need of high-temperature treatment.

Description

technical field [0001] The invention belongs to the field of dye-sensitized solar cells, and relates to a packaging material for dye-sensitized solar cells and a packaging method using the packaging material. Background technique [0002] With the increasing severity of the global energy crisis, people are eager to find a sustainable clean energy source. Solar energy, as an inexhaustible natural energy source, has increasingly attracted the attention of countries all over the world. Compared with traditional silicon solar cells, dye-sensitized solar cells have low cost and simple fabrication, and have become a research hotspot of scholars from all over the world. [0003] At present, the photoelectric conversion efficiency in the dye-sensitized solar cell laboratory has reached more than 11%, and the efficiency of related battery components developed by Sony, Sharp and other companies has reached 8.5%, but this technology has not yet achieved real industrialization. , one ...

Problems solved by technology

However, in actual operation, this encapsulation method requires precise control of temperature and pressure, otherwise it is very easy to cause cracks and damage to the battery, and high temperature will damage the organic dyes that provide electrons in the battery, reducing the performance of the battery. When the temperature is high, the polymer film will melt or age, and lose the function of protection and packaging, thus greatly limiting the application of dye-sensitized solar cells
