The most recent 210mm n-type industrial tunnel oxide passivated contact (i-TOPCon) module from leading Chinese module manufacturer Trina Solar has reached a remarkable maximum power output of 740.6W, setting a new record for this module category.
Although the solar module is not currently on the market, its production involves several advanced processes, as described by Trina Solar, such as laser-induced firing and edge passivation, which have enhanced the module’s efficiency.
The power output of the module was verified by the German certification firm TÜV SÜD, with the company highlighting that this marks the 26th occasion where its products have established records in power conversion efficiency and power output.
“Each breakthrough stems from our unwavering dedication to technological innovation and excellence,” stated Gao Jifan, Chairman and CEO of Trina Solar, and Director of the company’s State Key Laboratory of PV Science and Technology.
“The continuous advancement in i-TOPCon technology highlights Trina Solar’s competitiveness and commitment to leading the way in the 700W+ era and the 210mm n-type advanced technology platform.”
Following the introduction of an i-TOPCon module for the commercial and industrial rooftop sector earlier this year, Trina Solar has now unveiled this latest development. Although the company has not disclosed the power conversion efficiency of this new module, its previous i-TOPCon product achieved an efficiency of 22.7%. Additionally, Trina Solar recently enhanced the efficiency of its leading Vertex N range of modules to 23.2%, demonstrating the company’s commitment to enhancing the efficiency of its product offerings.
In the module manufacturing sector, significant innovation has emerged in recent months, highlighted by JinkoSolar’s introduction of a ‘zero carbon’ TOPCon module. TÜV Rheinland, a member of the TÜV Association, has accredited the manufacturing processes for utilizing renewable energy sources, showcasing the industry’s drive for innovation in manufacturing practices.
Edge passivation, a crucial technique employed in the creation of Trina Solar’s newest module, has garnered significant focus in module design advancements. In the previous year, a team of researchers from DAS Solar and the Chen Group introduced an “organic passivation film” designed for module assembly. This innovation aims to alleviate some of the efficiency losses associated with cutting and separating processes essential in the manufacturing of shingle panels.
