Problems solved by technology

[0002] In solar cells, thin-film cells have the advantages of low production cost, easy large-scale continuous production, and good weak light effect, but have disadvantages such as low cell conversion efficiency.
In thin-film batteries, laser scribing plays a very important role in thin-film batteries. In order to increase the conversion efficiency of thin-film batteries, it is necessary to scribe multiple parallel grooves on the substrate. The existing device structure for parallel scribing complex, difficult to adjust

Abstract

The embodiment of the invention provides a method and a device for realizing parallel rit of large-format multi-path laser and relates to the field of laser grooves. The device comprises a laser transmitting module, a laser diffraction module and laser focusing module sequentially arranged, wherein the laser diffraction module is used for dividing laser into at least two sub laser beams; the laserfocusing module is used for focusing the at least two sub laser beams; and the focused at least two sub laser beams are used for substrate grooves. The method and the device can realize parallel processing of multi-path laser and facilitate the efficiency improvement of engraving parallel grooves through laser.

Description

technical field [0001] The invention relates to the field of laser scribing, in particular to a method and device for realizing large-scale multi-channel laser parallel scribing. Background technique [0002] In solar cells, thin-film cells have the advantages of low production cost, easy large-scale continuous production, and good weak light effect, but have disadvantages such as low cell conversion efficiency. In thin-film batteries, laser scribing plays a very important role in thin-film batteries. In order to increase the conversion efficiency of thin-film batteries, it is necessary to scribe multiple parallel grooves on the substrate. The existing device structure for parallel scribing Complicated, not conducive to adjustment. Contents of the invention [0003] The purpose of the present invention includes, for example, providing a method and device for realizing large-scale multi-channel laser parallel scribing, which has the characteristics of simple structure and ...
