Description
Technical Field
A laminating device for manufacturing a solar cell module belongs to the technical field of solar cells, and particularly relates to a manufacturing technology of the solar cell module.
Background
With the development of economic society, the use of a large amount of conventional fossil energy causes serious environmental pollution, and the development and utilization of clean energy has become a common consensus of people. The solar energy is inexhaustible, clean and pollution-free, and is the most ideal and sustainable renewable energy source in the future. Solar cells directly convert light energy into electrical energy, which is an important way of solar energy utilization. At present, the most commonly used solar cell is formed by cleaning and texturing, PN junction preparation, antireflection film preparation and metal electrode preparation on the basis of a silicon wafer.
The silicon heterojunction solar cell is based on crystalline silicon, and is formed by cleaning and texturing, sequentially depositing an intrinsic amorphous silicon layer and an N-type amorphous silicon layer on a first light-receiving surface on the front surface of the crystalline silicon, and sequentially depositing an intrinsic amorphous silicon layer on a second light-receiving surface on the back surface of the crystalline siliconThe silicon heterojunction solar cell comprises a silicon layer and a P-type amorphous silicon layer, Transparent Conductive Oxide (TCO) is deposited on a first light receiving surface and a second light receiving surface at the same time, and finally metal electrodes are prepared on the first light receiving surface and the second light receiving surface by using a silk-screen printing technology and adopting thermosetting low-temperature resin slurry to obtain the silicon heterojunction solar cell. In the silicon heterojunction solar cell, the amorphous silicon layer contains a large number of hydrogen bonds and silicon dangling bonds, so that the amorphous silicon layer can play a role in passivating the crystalline silicon interface well, and the open-circuit voltage (V) of the solar cell is improvedOC) And photoelectric conversion efficiency. Highest temperature of silicon heterojunction solar cell in whole preparation process<At 250 ℃, the passivation effect of amorphous silicon can be damaged by high temperature after the deposition of the amorphous silicon layer, so that the conversion efficiency of the battery is deteriorated. For a silicon heterojunction solar cell, under the condition of a temperature less than 200 ℃, 1-60 sunlight intensities (suns) are applied to the solar cell, so that the passivation effect of an amorphous silicon layer on a crystalline silicon interface can be obviously improved, and the conversion efficiency of the solar cell is further improved, wherein the process is called light-soaking treatment (light-soaking), and the light-soaking treatment is usually carried out immediately after the preparation of the cell is finished.
In order to generate electricity by using solar cells on a large scale, the solar cells need to be combined in series and parallel to prepare a solar cell module.

The silicon heterojunction solar cell is subjected to long-time high-temperature incomplete destruction, the microstructure of amorphous silicon in the silicon heterojunction solar cell can be changed, the hydrogen content is reduced, the lattice order is increased, the passivation effect of the amorphous silicon on the heterojunction solar cell is weakened, and the cell conversion efficiency is reduced.
