LONGi Solar announced today that the company has developed the technology of 
"Seamless Soldering", which completely eliminates the gap between cells and 
increases the efficiency of PV modules. The technology is planned for mass 
production in 2H-2019. According to a TUV SUD test on May 30, "Seamless 
Soldering" technology, when combined with innovative module design, has the 
potential to push LONGi Solar's high efficiency PERC module power record to 
500Wp.

"Seamless Soldering" technology uses a solder ribbon to achieve "tiled" 
interconnection of the cell, completely eliminating the typical 2mm wide cell 
gap, thus 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 wafer, thin 
silicon wafer, soldering wire and reflective ribbon.

PV module technology continuous pursuits in the evolution of high efficiency 
and high power 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 LONGi's modules. LONGi will continue to invest 
in technology to promote a wider range of PV applications of PV in the world.
