Problems solved by technology

[0003] In practical applications, if the internal structure of the cell is exposed to the air for a long time, it will absorb moisture in the air and cause the electrolyte to fail
Oxygen in the air will oxidize the organic matter in the electrolyte, resulting in a decrease in the photoelectric conversion efficiency of the cell

Embodiment Construction

[0013] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0014] Place all-solid-state dye-sensitized solar cells, hot-melt adhesive film (preferably EVA), polyester film (preferably PET) in the working area of ​​the laminator layer by layer, heat the heating plate to 70-120°C, and vacuum for 4~ 6 minutes, pressurize and maintain for 4-8 minutes. Naturally cool to room temperature. Then, apply glass glue on the sides of the battery sheet, add a resin frame and fix it, and cure for 48 hours at room temperature to complete the packaging of the all-solid-state dye-sensitized solar cell.

[0015] The hot-melt adhesive in this embodiment is a solvent-free, moisture-free, 100% solid-melt polymer, which is solid at room temperature and becomes fluid and viscous when heated and melted to a certain extent. A liquid adhesive whose main component is a copolymer of ethylene and vinyl acetate.

Abstract

The invention discloses an encapsulating method for an all-solid-state dye-sensitized solar cell. A laminating machine is used, a waterproof oxygen-insulation anticorrosive back film is bonded on the back surface of a cell plate through hot melt adhesive, a resin side frame is installed around the cell plate and glass cement is used for sealing and fixation. The invention has the advantages that the technology of the method is simple, the cost is low, the trouble that the all-solid-state dye-sensitized solar cell absorbs water and oxygen is particularly solved, and the stability of the all-solid-state dye-sensitized solar cell is effectively improved.

Description

technical field [0001] The invention relates to a packaging method of a solar cell, in particular to a packaging method of an all-solid-state dye-sensitized solar cell. Background technique [0002] So far, the reported efficiency of dye-sensitized solar cells has reached 11.5%. Its high photoelectric conversion efficiency, low cost and non-polluting characteristics make the third-generation photovoltaic industry attract more and more people's attention and support. In the process of realizing the industrialization of solar cells, the stability of solar cells has always been one of the most concerned issues for researchers. Liquid dye-sensitized solar cells are composed of two pieces of conductive glass, which are bonded with a hot-pressed film in the middle. This structure has very high requirements for the precision of the packaging process, and the cost is high, which is not conducive to the realization of industrial production. In addition, there are many practical prob...
