Multek supports the innovation in the solar assembly business with MWT/EWT technology by supporting large form factor solar BACK CONNECT BACK SHEETS.

"The first innovation in 30 years in the solar assembly business"

MWT / EWT Cell & Assembly Technology with BACK CONNECT BACK SHEETS offers the following benefits to the customer.

Increased Sunlight to Power Conversion

• Higher current output efficiency due to lower DC resistance on the cell to panel interconnect
• Higher current output efficiency due to less front contact coverage of the Si by the stringing tabs
• Overall 3-10% sun light conversion improvement

Significant Solar Module Productivity Gains

• Higher yields in assembly due to less wafer breakage
• Higher throughput – 3 x the speed of H Cells assembly
  • Fewer operators
  • Less space consumption compared to H-Cell lines
  • Thinner cells can be processed
• Overall higher productivity and lower cost assembly

Aesthetics of solar panels is much improved

• Nicer look
• More color variations
• Better fill factor (cells spaced more closely in a panel)

Improved Module Power Output Distribution

• Significantly better output consistency from Solar Panel to Solar Panel
