JinkoSolar, one of the world’s leading photovoltaic manufacturers, has once again pushed the boundaries of solar technology. The company announced that its next-generation high-efficiency cell, built on the TOPCon technology platform, has achieved a certified conversion efficiency of 27.79%, setting a new global benchmark. This latest milestone represents the 31st world record JinkoSolar has achieved in cell efficiency and module power.
This breakthrough reflects the company’s strategic focus on innovation and its sustained investment in core TOPCon advancements. At the heart of the achievement is a newly engineered passivated contact structure. By optimizing composite passivation materials and refining related processes, JinkoSolar has significantly reduced carrier recombination losses, resulting in improved overall performance.
The technology also incorporates ultra-low optical parasitic absorption, enabling more effective utilization of incoming light. This, combined with cutting-edge metallization techniques—featuring newly developed metal materials and a more precise electrode architecture—enhances the efficiency of carrier collection from photogenerated carriers.
With this latest record-setting performance, JinkoSolar continues to reinforce its leadership in solar cell technology and drive the future of high-efficiency photovoltaic innovation.
