G1 solar cell size plays an important role in the first unified standard size of monocrystalline perc in the module. G1 perc bifacial solar cell 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 silicone sheet with thickness and diagonal line.

Sunrise Energy selected global high-quality G1 cells, equipped with non-destructive scratches, 9BB half cell, precision encapsulation, and other technologies, which can achieve the power of 415W.

G1 solar cell size 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 solar cell 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 MBB solar cell can be improved, and the impact on the performance of the perc modules 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, MBB solar cell 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.

Applications of the G1 Solar Cells

G1 cell is mainly used in 120, 132, 144 cell solar modules. It is representative of small size modules. The G1 module is encapsulated by Sunrise G1 solar cell with power up to 415w, and also provide full black, double glass and bifacial mono perc half cell and other customization.
