Model MWT -Solar Module
Phono Solar is the leader of MWT mass production. MWT technology has High compatibility with conventional cells equipment, High technical threshold, complex technical process.
Conventional Al-BSF cell: Oversupply
LOW technical threshold (mono19.8%, poly18.4%)game console, portable cooler, coffee maker, and more.
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.
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.
Technical compatibility
Good compatibility with other technologies, including black silicon, PERC, etc.
Personalized customization
The pattern of MWT cell finger can be customized.
