Compared with TOPCon 4.0 solar cell technology, its cell efficiency can be improved by 0.4%-0.55%, and the bifaciality can be increased by 5%.
Adopting 210mm large-size silicon wafers, effectively enhances the photovoltaic conversion efficiency and improves the reliability of the solar panels.
The super multi-busbar design increases the number of solder strips and main busbar solder points, resulting in a more uniform stress distribution of PV cells. This enhances tolerance to hidden cracks and broken grids and shortens the current transmission path; in this way, the series resistance is reduced, effectively enhancing current collection capability and improving optical utilization.
