Meyer Burger's SWCT selected by Panasonic Solar

Meyer Burger Technology Ltd today announced an agreement with Panasonic Solar for the installation and accelerated evaluation of its SWCT platform for the connection of HIT cells. With its heterojunction cell technology, Panasonic is one of the pioneers in the development and manufacture of high efficiency solar cells and modules. By implementing Meyer Burger's SmartWire Connection technology to connect its HIT cells, Panasonic expects to further increase the strength of its high efficiency PV modules. SmartWire Connection Technology (SWCT) is the natural evolution in cell connection technology.

Meyer Burger's ground-breaking SmartWire Connection Technology employs an innovative foil-wire electrode with up to 24 perfectly aligned wires to connect solar cells. This reduces silver consumption per heterojunction solar module by over 50% which in turn reduces production costs for solar module manufacturers. The resulting dense wire contact matrix enables SWCT modules to easily cope with the increased power extraction necessary for today's high efficiency heterojunction solar cells thereby delivering an increased performance yield in SWCT solar modules. The resulting structure of a SWCT module significantly strengthens its stability and enhances its lifetime. This powerful combination of higher energy yield, longer module lifetime and lower manufacturing costs make SWCT the most cost effective method of connecting solar cells on the market today.

Panasonic's technology is industry-leading high performance technology. Panasonic produced PV modules HIT have a unique silicon heterojunction structure composed of crystalline silicon substrate and amorphous silicon layers. This technology performs the junction formation needed for solar cells by surrounding the crystalline silicon wafer with an amorphous silicon layer. Its high passivation capability compensates for multiple defects that occur around the surface of the silicon wafer. With industry-leading conversion efficiency and excellent temperature coefficient characteristics, Panasonic achieves high power generation even in a limited space. Panasonic has started to supply HIT cells with partners in addition to PV modules. Panasonic will expand BtoB business with partners globally. HIT is a registered trademark of Panasonic Group.

The delivery and installation of Meyer Burger's SWCT equipment at Panasonic's R&D facility located in Osaka, Japan is planned in the second quarter of 2018 and is an initial step towards extending the adoption of SmartWire Connection Technology to other manufacturing locations.
