This equipment integrates laser cutting and cross-sectional passivation into one. It can be used in the previous process of stringer to perform laser cutting on the full cell, and then passivate the cross-sections of the half cutting or multiple cutting cells. This can effectively reduce the recombination loss on the cutting surface, increase the open-circuit voltage and fill factor of the cell, and thereby enhance the conversion efficiency of the cell.
Features
1. It integrates cutting and passivation into one, including functions such as full cell feeding, automatic cutting, cross-sectional passivation, and automatic packaging and discharging;
2. Strong compatibility. Replace some of the kits to be compatible with 1/2 cell, 1/3 cell and 1/4 cell;
3. High production capacity. A single unit can achieve the passivation of 14,000 half-cell per hour;
4. It occupies a small area and can be optionally equipped with a power sorting function;
5. Without the use of special gases, it can be applied in module workshops, saving input costs.
