Key takeaways:
Dinto Solar plans to launch a 1/3-cut HJT module in multiple formats for different PV application scenarios
The multi-cut layout is designed to reduce resistive losses and increase module power while lowering mechanical stress on individual cell pieces
The product reflects the growing adoption of multi-cut cell layouts in high-efficiency PV module designs
The adoption of multi-cut cell layouts is gaining popularity, thanks to solutions that passivate the edges after cutting. Companies are also commercializing modules with multi-cut cells, and one such TOPCon product from JA Solar is featured in TaiyangNews’ TOP SOLAR MODULES.
Heterojunction (HJT) manufacturers like Dinto Solar are also following this trend, as slicing cells into smaller pieces reduces resistive losses and improves the module’s overall power output.
Established in 2017 by the Central Research Institute of State Power Investment Corporation (SPIC), Dinto Solar plans to launch a 1/3-cut cell layout module at Intersolar Europe 2026. The product will be available in 3 different formats for various application scenarios. It is well known that HJT modules have a higher inherent bifaciality than TOPCon modules. Dinto claims a bifaciality of up to 98% for its multi-cut module; for reference, mainstream HJT modules featured in TOP SOLAR MODULES have a bifaciality up to 95%.
The company claims a maximum power output of 765 W for this module, but its maximum efficiency figures remain unknown at the time of this article's publication.
Apart from the power advantage, a multi-cut layout also offers additional reliability advantages. With smaller cell slices, the mechanical stress on individual cells is lower, preventing the risk of microcracks.
Integrated PV (IPV) applications, such as building-integrated PV (BIPV), fencing, agri-PV, and roadside infrastructure, are gaining popularity in Europe, and Dinto plans to target these segments with its latest multi-cut-cell HJT module, where vertical PV is ideal.
