JinkoSolar Achieves Milestone Breakthrough with TOPCon Cell Technology, Setting New Record of 27.79% Conversion Efficiency

[Core Summary]
JinkoSolar, a globally highly innovative photovoltaic enterprise, announced today that the conversion efficiency of its N-type TOPCon (Tunnel Oxide Passivated Contact) solar cell has successfully broken through to 27.79%. This achievement has obtained independent testing certification from the world's authoritative testing organization, the Institute for Solar Energy Research in Hamelin (ISFH) in Germany, marking JinkoSolar's leading position in the research and development of next-generation high-efficiency battery technology.

[Technical Details]
This efficiency breakthrough benefits from JinkoSolar's continuous in-depth cultivation and integration of multiple technological innovations in the TOPCon technology route, including:

Precision growth technology for ultra-thin tunnel oxide layers, achieving excellent surface passivation effects.
Optimization of the polysilicon contact layer, significantly reducing recombination losses in the metal contact areas.
Collaborative design of rear-side passivation and optical enhancement structures, improving the cell's ability to collect and utilize photogenerated carriers.

[Industry Impact]
Conversion efficiency is a core indicator for measuring the advancement of photovoltaic technology. Every 0.1% improvement means a step forward in the utilization of solar energy resources. JinkoSolar's transition of the 27.79% efficiency record from the laboratory to industrialization will bring significant value to downstream applications:

Higher power output from photovoltaic modules under the same area, effectively improving power generation efficiency and reducing the Levelized Cost of Energy (LCOE).
Facilitating the efficient and intensive use of land and rooftop resources, delivering better investment returns for large-scale ground-mounted power stations and distributed photovoltaic projects.
Accelerating the global energy structure's transition to clean and renewable energy, providing stronger technical support for achieving the "Dual Carbon" goals.

JinkoSolar will continue to commit to the optimization and mass production process of TOPCon technology, promote the widespread adoption of efficient clean energy, and lead the photovoltaic industry to new heights.
