Half chip is one of the most effective ways to improve the power of photovoltaic modules at present. By dividing the whole cell into half chips, the string current is reduced, so as to reduce the power loss of series resistance, in order to achieve the effect of improving the power of modules. According to the current mass production data of the first-line photovoltaic module factory, the power of half module is increased by 6 ~ 7W, and the effect is remarkable.

 Application
The automatic laser splitting machine is used for the automatic production of high-efficiency photovoltaic modules.
The scribing module can reduce the string current and reduce the resistance loss, so as to improve the output power of the photovoltaic module.
