Laser cutting solar cell into half piece or 1/3 piece can increase the output of the solar panel power. It can reduce the solar string cell current and reduce the voltage drop loss of the string series resistance. It has been confirmed the significant power gain (2-3%) to the solar panel after cutting the cells into small pieces, Therefore, it is widely concerned and has been pushed into a mass production.
The traditional laser slicing machine currently on the market realizes the function of cell slicing through laser processing and mechanical splitting. It generates dust too much and pollutes the working environment; and cannot avoid the micro cracks caused by the mechanical splitting in the production. , And also reduce the comprehensive bending strength of the solar cell, it will be more risk of cracking for solar cell.
