Description

Technical Field

[0001] The invention relates to the technical field of texturing of silicon substrates of PERC cell slices, and in particular to a texturing device for silicon substrates of PERC cell slices. Background Art

[0002] With the continuous development of PERC cell technology, the requirements for silicon substrate texturing technology are becoming higher and higher. By forming a velvet structure on the surface of the silicon substrate, the reflectivity of the silicon wafer surface to sunlight can be effectively reduced, thereby increasing light absorption and improving the photoelectric conversion efficiency of the cell. Generally, the reflectivity can be reduced from about 30% of the flat silicon wafer surface to less than 10%. In the future, the texturing process will pay more attention to improving the uniformity of the velvet surface, reducing the reflectivity and reducing surface damage.

[0003] The existing PERC cell silicon substrate texturing equipment cannot stably take out materials, because most of the PERC cells are now stacked together. When taking the upper PERC cell, it is easy to cause the lower PERC cell to shift, which will affect the next material taking, making it difficult to quickly and stably feed the PERC cell. Secondly, only one side of the PERC cell can be texturized, and secondary processing is required, which affects the overall processing economic benefits and product quality, and it is difficult to meet actual processing needs. Therefore, we propose a PERC cell silicon substrate texturing equipment. Summary of the invention
