Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a cell slicing machine. Background Technology

[0002] In the traditional production process of photovoltaic module cells, laser slicing equipment and processes are usually used. Laser slicing uses a high-power-density beam to irradiate the solar cell, which quickly heats the cell to its vaporization temperature and evaporates to form holes.
