At present, lasers are usually used to cut battery cells. However, the intensity and density of the laser are different, and the degree of damage to the battery cells is different. In severe cases, the leakage current of the cut battery cells is too large, causing widespread harm.
Laser cutting is the most widely used laser processing technology. Its principle is that the laser is focused and irradiated onto the material, causing the temperature of the material to rise sharply to melt or vaporize. With the relative movement of the laser and the material being cut, the material is cut. A slit is formed on the material to achieve the purpose of cutting.
Laser cutting occupies a large proportion in laser processing applications (currently laser cutting accounts for more than 70% of laser processing), and its application in the photovoltaic industry is becoming more and more widespread. Compared with traditional cutting methods, laser cutting has incomparable advantages, mainly in:
①. High cutting precision, narrow slit, good quality, small heat-affected zone, and the cutting end face is flat and smooth;
②. Fast cutting speed and high processing efficiency;
③. It is a non-contact cutting. It has no mechanical processing force, no deformation, and no pollution problems such as processing chips, oil stains, noise, etc. It is a green and environmentally friendly processing;
④. Strong cutting ability, can cut almost any material.
However, laser cutting of battery cells also has some disadvantages, mainly reflected in:
① When the laser is cutting, it will cause certain damage to the crystal phase of the battery cells, which will cause damage and cracks to a certain extent;
②. After the crystal phase of the cell is damaged, the solar module produced will have the risk of leakage during operation. This article mainly uses experiments to verify the impact of laser intensity and density on solar cells during laser cutting.
