In November 2022, JinkoSolar launched its first N-type TOPCon Tiger Neo module and, as of the end of August, had sold 120GW of the product.
With TOPCon, HJT and BC technologies emerging during 2023, it was only in 2024 that the industry reached a consensus on TOPCon as the next dominant force after PERC, currently projected to represent 70% of all global module sales, a significant increase from 15% in 2023. This shift could signify a tipping point for the acceleration of TOPCon adoption in the market.
With Jinko the largest owner of TOPCon patents, the company’s R&D strength has converted various technological breakthroughs into cost-efficient products. As of the end of 2023, it held 460 authorised TOPCon patents, with a further 980 registered, openly accessible at a reasonable rate. While all module manufacturers have had access to these patents under licensing and grant models, they appear to have catalyzed significant advancements primarily in the N-type era.
During 2024 Jinko has agreed to grant TOPCon patents to two other top 10 manufacturers, negotiating the transfer of data collected in their lines to enhance its own autonomous process upgrading algorithms. The company’s early involvement, particularly through intensive investment and patent portfolio establishment aimed at stimulating R&D, technological standardization and environmentally sustainable solutions, has significantly accelerated the global production and adoption of TOPCon technology.
