The size of the G1 cell plays an important role in the first unified standard size of monocrystalline in the module. The size is 158.75mm which has the advantages of lower production costs, higher power, and higher acceptance of the cell side on the premise of specsquare monocrystalline silicon sheet with thickness and diagonal line.

The size of the G1 cell is 158.75-158.75mm. The dicing process in module production is divided into full and half. There are 5BB and 9BB. The appearance of Sunrise selection is zero defects. G1 size mono cell with higher welding ability, considering cell efficiency, production yield, and market analysis, it is confirmed that 9BB is the best solution. Innovative PERC technology and 9BB design shorten the current transmission distance and reduce the resistance loss. So that the conversion efficiency of the cell can be improved, and the impact on the performance of the module is reduced.

9BB P-type bifacial half-cut cell can contribute up to 30% of the gain in the module power generation process. The half-cut cell technology has higher conversion efficiency than the full cell and has a lower rated operating temperature. Compared to the full cell module, the half cell module temperature is 2-3 degrees lower, and the hot spot temperature is 10-20 degrees lower, At the same time, it has a lower shadow mask loss.
It has better IAM performance than conventional flat ribbons when light is incident. The 9BB with a smaller ribbon design can reduce the impact of stress. Make the module resistant to high and low-temperature performance and mechanical load performance.
