Introduce：
Laser film opening technology uses ultra short pulse lasers to remove surface materials, which has the advantages of speed and accuracy. This method can be applied to any area without causing significant thermal effects on the material, thus protecting the surface of the material. The application of laser technology in photovoltaic BC film opening not only improves production efficiency, but also achieves efficient processing of materials through precise control of laser parameters, promoting the progress and application of BC cell technology.
