UV laser cutting machine for cutting and scribing solar panels

       As the global shortage of primary energy becomes more and more severe, the development and utilization of clean energy has become an urgent problem to be solved in various industries around the world. Solar cell is a device that can convert light energy into electrical energy, mainly silicon-based solar cells, which can effectively reduce environmental pollution and the crisis of energy consumption. As one of the important application technologies in the industrial field, laser cutting technology plays a very important role in the field of solar cells. Compared with other processing technologies, laser cutting technology is more efficient. On the one hand, it improves process reliability and on the other hand reduces Cost of production. These advantages have been fully embodied in the production of crystalline silicon solar cells and thin-film solar cells.

       Compared with traditional methods, laser cutting technology has unique advantages, mainly in the following aspects: 1) High cutting accuracy, narrow kerf, good quality, small heat-affected zone, and the cutting end surface is flat and smooth; 2) Fast cutting speed , High processing efficiency; 3) It is a non-contact processing, there is no mechanical processing force, no deformation, no pollution problems such as processing chips, oil stains, noise, etc., it is a kind of green processing; 4) Strong cutting ability , Can cut almost any material.
