SmartWire Connection Technology

SWCT is the most cost-effective method of connecting cells. It employs a foil-wire electrode instead of the conventional cell connectors (ribbons). This results in significant improvements in efficiency while reducing the negative effects of possible micro-cracks to a minimum.

Solar cell connection technology SWCTTM

SmartWire Connection Technology was developed for use in connecting current and future generations of solar cells. This technology is available exclusively from Meyer Burger.

SWCT™ is an entirely new way to connect cells. This patented technology allows very cost-effective and resource-friendly mass production of high-performance, top-quality solar modules.

SWCT™ is extremely flexible and powerful: almost all cell and module types can be processed, including state-of-the-art developments such as bifacial HJT glass/glass solar modules.

Benefits of SWCT technology to connect solar cells

  • Higher output in the module
    Thanks to the dense contact matrix, the solar cells exhibit a significantly higher efficiency. In comparison to conventional 3-busbar technology, SWCT delivers an increased performance yield of 6% for solar cells thanks to encapsulation in the module.
  • Less silver in cell production
    Cells without busbars require up to 80% less silver.
  • Reliable modules with higher energy yield
    Our modules have passed extended IEC- and UL certification tests successful.
    Bificial modules with SmartWire Connection Technology shows an increased energy yield in terms of kWh/Wp under real outdoor conditions.

  • Combination for high performance
    Heterojunction cells combined with the SmartWire Connection Technology have achieved module efficiencies of more than 20%. In combination with new-module designs (e.g. glass/glass modules) this results in essential lower energy costs ($/kWh).
