Phono Solar is the leader of MWT mass production. 
MWT technology has High compatibility with conventional cells equipment, High technical threshold, complex technical process.

 

Unlike standard solar cells, 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. The MWT architecture thus achieves higher efficiencies while keeping the manufacturing costs low. 

The interconnection in the module can be realized by using either structured cell interconnectors or conductive back sheets.
