The roll out of mass production for the technology is planned for the third and fourth quarter of 2019. According to a recent TÜV SÜD test, the “seamless soldering” technology, when combined with innovative module design, has the potential to push LONGi Solar’s high efficiency PERC module power record up to 500Wp.
Seamless soldering technology uses a solder ribbon to achieve ‘tiled’ interconnection of the cells, completely eliminating the typical 2mm gap between cells, and thereby increasing efficiency while reducing the BOM cost of the module. This technology is perfectly compatible with existing module encapsulation processes and equipment. It has high mass production maturity and stability, and capacity is easily scalable. In addition, seamless soldering has good technical compatibility that integrates with M6 monocrystalline silicon wafers, thin silicon wafers, soldering wires and reflective ribbons.
PV module technology is continuously undergoing a process of evolution towards higher efficiency and higher output. These are the key factors in reducing the LCOE. LONGi has carried out intellectual property research on “seamless soldering” technology and has applied for a number of related patents. The launch of this technology marks a new step in the innovations of PV modules. (mfo)
