Major Chinese module manufacturer Trina Solar’s latest 210mm n-type industrial tunnel oxide passivated contact (i-TOPCon) module has achieved a maximum power output of 740.6W, a record for this type of module.

While the module is not yet commercially available, its manufacture incorporates a number of what Trina Solar called “advanced processes,” including laser-induced firing and edge passivation, which have improved the efficiency of the module.

German certification and certification firm TÜV SÜD confirmed the power output of the module, and the company notes that this is the 26th time that its products have set records in power conversion efficiency and power output.

“Every breakthrough is the result of our relentless pursuit of technological innovation and excellence,” said Gao Jifan, chairman and CEO of Trina Solar and director of the company’s State Key Laboratory of PV Science and Technology.

“This sustained leadership in i-TOPCon technology underscores Trina Solar’s competitiveness and drive in spearheading the 700W+ era and 210mm n-type advanced technology platform.”

The news follows Trina Solar’s launch of an i-TOPCon module for use in the commercial and industrial rooftop sector earlier this year. While the company did not announce the power conversion efficiency of its latest module, its earlier i-TOPCon product has a conversion efficiency of 22.7%, while it recently increased the efficiency of its flagship Vertex N range of modules to 23.2%, as Trina Solar looks to improve the efficiency of its products.

There has been considerable innovation in the module manufacturing space in recent months, with JinkoSolar announcing a ‘zero carbon’ TOPCon module. TÜV Rheinland, another member of the TÜV Association, accredited the manufacturing processes as using renewable power, as module manufacturers look to innovate in the manufacturing processes.

Edge passivation, the process used in the production of Trina Solar’s latest module, has seen particular attention in the module design space. Last year, researchers from DAS Solar and the Chen Group developed an “organic passivation film,” which can be used in module assembly, and could mitigate some of the conversion efficiency losses endured during the cutting and separating processes necessary in the production of shingle panels.

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.
