JinkoSolar Achieves 34.82% Conversion Efficiency with N-type TOPCon Perovskite Tandem Cell — Sets New World Record, 33rd Global Record to Date

JinkoSolar has announced that it has achieved a conversion efficiency of 34.82% in its self-developed N-type TOPCon perovskite tandem cell, certified by the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences. This surpasses its previous world record of 34.76%, marking JinkoSolar’s 33rd update to the global record for solar cell conversion efficiency and module output.

This achievement represents a significant technological breakthrough in the tandem cell field, combining N-type TOPCon and perovskite technologies. The efficiency improvement was realized through multiple core technological innovations, including a composite passivating contact structure in TOPCon cells, multi-dimensional interface passivation technology, crystal growth control, optical coupling, and light management techniques.

As the world’s first solar company to achieve mass production of N-type TOPCon technology, JinkoSolar has consistently advanced量产 processes while simultaneously developing next-generation technologies. Today, TOPCon is widely adopted as one of the mainstream technologies in the global market, highly regarded for its high efficiency and high reliability.

This latest record demonstrates steady progress in integrating mass-proven TOPCon technology with perovskite, a next-generation photovoltaic technology. It serves as a critical milestone toward higher future efficiencies and lower power generation costs, representing a major step forward in the practical application of next-generation solar cells.

Going forward, JinkoSolar will continue to expand the potential of photovoltaic power generation through technological innovation, advancing R&D in both TOPCon and perovskite tandem technologies, and contributing to the realization of a sustainable energy society by delivering higher-efficiency, more reliable solar power solutions.
