China-based solar cell and module manufacturer Jinko Solar announced achieving a record maximum solar conversion efficiency of 26.1% in its 182 mm N-type module, which is Jinko’s latest TOPCon (tunnel oxide passivated contact) cell technology.

In a recently released statement on the development, Jinko said that the maximum solar conversion efficiency of its 182 mm N-type module reached 23.86% in the current experiment, surpassing the record of 23.53% for N-type module, also set by Jinko in July this year.

The module adopted Jinko’s TOPCon cell technology and advanced welding and packaging technology. It achieved a conversion efficiency of 23.86% for the first time for 2 mm square above large-size solar modules.

Jinko’s record efficiencies were confirmed by TÜV Rheinland, which provides a globally unique testing standard 2 PfG 2796/02.22 for the certification of building-integrated photovoltaic modules (BIPV).


The results achieved by Jinko using its latest TOPCon technology establish the practical foundation needed for the mass production of subsequent advanced products. The technology effectively reduces the internal resistance loss of the module while significantly improving the conversion efficiency.

Chief Technology Officer of Jinko Solar Hao Jin said, “We are pleased to make another breakthrough in module conversion efficiency, leveraging our accumulated experience and continuous efforts in N-type technology R&D and mass production. It is both a recognition and an incentive for our R&D (research and development) capabilities. We will drive industrial progress through constant technical upgrades in product structure, materials, and processes, catering to clients’ demands for high-efficient and more reliable N-type products.”

Jinko Solar’s module shipments for the third quarter of 2022 surged by 160% sequentially to approximately 3 GW.

In another collaborative research performed last month, scientists from China, Australia, and Singapore achieved a maximum power conversion efficiency of 22.8% in a 613-Watt TOPCon module with 60 cells. The teams achieved the results using a tube-type industrial plasma-assisted atomic layer deposition (PEALD) technique.
