Solar cell connection technology

20 Mar 2013

Solar cell connection technologyMeyer Burger’s patented, SmartWire Connection Technology (SWCT) for solar cells achieves higher efficiency solar modules, reducing production costs in PV manufacturing. Solar cells are electrically connected using thin copper wires on both sides of the cell, thereby replacing the classic two to three busbars. Typically, 30 very fine copper wires are used for cell connection, generating up to 2,000 contact points per cell. SmartWire Connection Technology (SWCT) offers customers the following advantages: five percent higher power output compared to best-in-class 3BB technology; a 10% higher energy yield (kWh/kWp); a reduction of production costs of up to 0.25 USD/cell; and SWCT is compatible to all crystalline silicon cell technologies. The SGS Fresenius Institute has already certified Heterojunction (HJT) modules with the SmartWire Connection technology, plus Meyer Burger’s laboratories have successfully performed four-fold, IEC-compliant damp heat, and eight-fold temperature cycles.
