The first of Trina Solar’s 210mm n-type i-TOPCon solar PV cells have been manufactured at its 8GW facility in Suqian, Jiangsu province, China. The cells are primarily intended for use in the new generation of its Vertex N modules.

Trina Solar said that its investments and developments in n-type TOPCon technology have led to high power output, efficiency, energy yield and reliability in its 210mm technology cells and modules. The Vertex N 605W modules use 210mm cells, and Trina said that they have recorded efficiencies of 22.4% with a design specifically tailored to 104-metre-long tracker systems. The modules received a carbon footprint certification from TÜV Rheinland in November last year.

The 8GW facility where the first cells have been produced began construction in July 2022 and manufacturing equipment was in place by November. The production line is mostly dedicated to 210mm TOPCon cells.

TOPCon technology has seen increased commitment across the solar industry of late. Canadian Solar announced plans to begin mass production of TOPCon modules in Q1 2023, with claims that its modules could reach up to 690W of power output.

PV Tech has been running PV ModuleTech Conferences since 2017. PV ModuleTech USA, on 21-22 May 2024, will be our third PV ModulelTech conference dedicated to the U.S. utility scale solar sector. The event will gather the key stakeholders from solar developers, solar asset owners and investors, PV manufacturing, policy-making and and all interested downstream channels and third-party entities. The goal is simple: to map out the PV module supply channels to the U.S. out to 2025 and beyond.

Astronergy has introduced its latest module product series, ASTRO N7 and ASTRO N7s, both of which utilise rectangular wafers. ASTRO N7, based on the 210mm*182mm wafer, is specifically tailored for utility-scale systems. It features dimensions of 2382mm*1134mm and a 66-cell layout design that effectively lowers Voc and increases string size. This design feature significantly reduces tracker and cable costs, leading to a reduction in LCOE by 0.44% to 4.37% compared to 182mm-wafer TOPCon modules. Furthermore, ASTRO N7 incorporates advanced cell and module technologies such as laser-induced firing, super multi-busbar, light-redirecting film, and double-layer coating glass to enhance module power output and reliability. Join us to explore the latest advances in module technology and how they can improve module performance and learn about the economic advantage of rectangular-wafer modules and their benefits at a system level.
