【Product description】
Metal Wrap Through (MWT) solar cells are interconnected on the rear side. The front grid is contacted by metallized vias that lead the current onto the rear side. This reduces shading on the front side and ohmic losses due to cell interconnection.
Key features of this family solar panel:
NO bus-bar
Less shading, higher conversion efficiency (absolutely improved by over 0.4%), reduce consumption of silver paste.
No welding belt
Avoid the performance degradation caused by welding stress and microcrack; meanwhile, it is also applicable thinner silicon wafer, which is helpful for reducing cost.
Personalized customization
The pattern of MWT cell finger can be customized.
