High-Efficiency Metal Wrap Through Technology for Silicon Solar Cells
The newest series of Metal Wrap Through (MWT) technology for high–efficiency rear side interconnected silicon solar cell designs.
- Specifically developed to provide up to 0.4% greater efficiency in MWT solar cell designs versus standard cell designs.
- Solamet® PV701 & PV71x paste is employed as a via paste and p-contact metallization for back side tabbing interconnects.
Key features include:
- Excellent electrical contact to front side silver grid structures
- High mechanical strength
- High shunt resistance
- High line conductivity
- Outstanding solderability as a p-contact metallization
