SNEC 2019: LONGi Solar to mass produce ‘Seamless Soldering’ cell interconnect technology
The seamless soldering technology is claimed to significantly reduce CTM (Cell to module) losses, which combined with high-efficiency PERC cells has the potential to push module power to the 500Wp level, according to tests undertaken by TÜV SÜD on May 30, 2019. Image: LONGi Solar
‘Solar Module Super League’ (SMSL) member, LONGi Solar expects to enter mass production of a newly developed ‘Seamless Soldering’ cell interconnect technology in the second-half of 2019.
The seamless soldering technology is claimed to significantly reduce CTM (Cell to module) losses, which combined with high-efficiency PERC cells has the potential to push module power to the 500Wp level, according to tests undertaken by TÜV SÜD on May 30, 2019.
The patent pending interconnect technology that is said to use a solder ribbon to achieve a ‘tiled’ interconnection of the cell, completely eliminating the typical 2mm wide cell gap architecture, while said to be compatible with existing module encapsulation processes and equipment, making it mature and stable for scaling to mass production.
LONGi Solar said that it would also be compatible with its large-area M6 monocrystalline silicon wafer, thin silicon wafers and soldering wire and reflective ribbon technology.
LONGi Solar recently launched at Intersolar Europe its Hi-MO4 modules that includes M4 sized (161.7mm x 161.6mm) mono wafers with upgraded PERC technology based on 6 busbars, with cell efficiency reaching 22.5% and the module peaking at 430Wp.
LONGi Solar launches next generation Hi-MO 5 module series
LONGi Solar has introduced its next-generation Hi-MO 5 Series modules with for utility-scale PV power plants. This PV Tech TechTalk Product Series webinar is designed to provide an overview of this new module that has 540Wp performance with gallium-doped, newly defined M10 (182mm x 182mm) wafers, half-cut monocrystalline PERC (Passivated Emitter Rear Cell) cells and 9BB (busbar) ‘Smart Soldering’ cell interconnect technology.

Companies to watch out for in the latest PV ModuleTech Bankability Ratings
About 20 PV module suppliers continue to dominate large-scale utility supply to the PV industry today, with a further 30 module suppliers routinely being chosen for projects in the 20-50MW range. This webinar shows how these 50 companies can be benchmarked from a bankability standpoint, by understanding each company’s strengths and weaknesses across manufacturing and financial operations. Head of research at PV-Tech, Finlay Colville, will preview the latest PV ModuleTech Bankability Ratings, revealing the module suppliers to watch out for in 2020 and beyond.
