Product Overview
Description
Ultra-high Power with 21.2% High Efficiency
Based on the 210mm large-size silicon wafer and monocrystalline PERC cell, the Vertex comes with several innovative design features allowing high power output of more than 455W. Excellent temperature coefficient and low irradiation performance brings the greater power. Furthermore, benefit from square mono cells and high-density encapsulation technology, the efficiency of Vertex can reach up to 21.2%.
Multi-busbar Technology
In comparison with the conventional 5 busbar design, the innovative multi-busbar design on the cell can shorten the current collection transverse path by 50% and thereby reduce remarkably the cell internal resistance, which contributes a 1% - 1.5% increase in the power output compared with 5 busbar design.
The MBB design can also mitigate the performance loss caused by blocked electrical pathways in case of cell microcracks and finger electrode erosion due to external factors.

PERC Technology
PERC Cell
The PERC cell has a passivated rear side and a laser grooving process, which significantly improves the cell efficiency.
Bifacial PERC
For a bifacial PERC cell, the Al back surface field is replaced by Al grid, hence render the majority of rear side transparent which enable the cell to absorb light and generate electricity from both sides.

Half-cut Technology
Half-cut cell technology is to cut the cell into two seperate parts by mature infrared laser, hence halve the working current. The thermal loss on the ribbon will be remarkably reduced and the module’s power increases by 2%. The reliability of module is also enhanced.
The combination of half-cut cell technology and bifacial module can amplify the gain over the effect of current-reduction.
