Embodiment 1
[0027] Embodiment 1: as figure 2 The photovoltaic module shown includes several slices of solar cells. The slices of solar cells are formed by cutting the solar cells. , this effect will be reduced due to the position parallel to the laser sliced lobes during welding.
[0028] Since the present invention performs laser slicing in a direction parallel to the main grid, if the image 3 The production process of the conventional half-cell module shown is a series of steps of laser scribing, splitting, welding, lamination, lamination, frame installation, junction box installation, and testing. The welding volume of the battery sheet is double that of the original production line , additional welding equipment needs to be added and modified.
[0029] In order to adapt to laser slicing parallel to the direction of the main grid, the present invention changes the sequence of welding, laser scribing, and slivers. Figure 4 The component preparation process shown is carried out, ...
