Application of laser drilling machine in photovoltaic industry

(Click 53 )

Laser drilling uses a high-energy-density laser beam to locally heat the material to a high enough temperature to evaporate, melt or vaporize it to form holes. The key to laser drilling lies in precise control of energy density, line speed and focus position to achieve precise processing of the required holes. Due to its precision and high quality, laser drilling has become an ideal choice for many industrial applications, such as the manufacturing of solar cells.

Laser cutting machine equipment manufacturer men-luck briefly introduces the main applications of laser drilling in the photovoltaic industry. ①Battery chip processing. Laser drilling is a commonly used method in solar cell processing. Through precise and efficient processing on silicon wafers, polycrystalline silicon wafers and other solar cell materials, the light absorption efficiency of the cells can be improved, reflection losses reduced, and photoelectric conversion increased. efficiency. ②Connect batteries and components. During the solar cell assembly process, laser drilling is required to create wire connection holes between cells to ensure smooth current transmission and reduce energy loss. In addition, during solar module manufacturing, laser drilling is also used to create holes and connection points for brackets, frames and other components. ③Photovoltaic glass backplane. Conventional photovoltaic cell modules only use photovoltaic glass as the cover plate, while the back plate and cover plate of double-glass modules use photovoltaic glass. Therefore, during processing and production, the backplane photovoltaic glass must be drilled at specific locations to lead the current wires of the photovoltaic cell modules to the junction box. Because conventional photovoltaic modules only use photovoltaic glass for the cover plate, while double-glass modules use photovoltaic glass for both the cover plate and the back plate, and the back plate photovoltaic glass must be drilled at specific locations to lead the current wires of the photovoltaic cell module to the wiring. box. Therefore, drilling photovoltaic glass backplane has become an essential process.

Laser drilling is widely used in the photovoltaic industry. It can not only improve the production quality of solar cells, but also improve the quality of its products. Through the application of laser drilling machine technology, the manufacturing quality, efficiency and reliability of photovoltaic modules are improved, further promoting the development and popularization of photovoltaic energy.
