JinkoSolar has teamed up with TÜV NORD and China General Certification Center (CGC) to release a new white paper, showcasing the evolution of its high-efficiency TOPCon technology and the performance of its latest Tiger Neo 3.0 modules.
As traditional PERC cells near their efficiency limits, JinkoSolar highlights how its n-type TOPCon structure—featuring a tunneling oxide and doped polysilicon layer—is paving the way forward with improved energy conversion, better temperature performance, and slower long-term degradation.
According to the white paper, JinkoSolar’s cell efficiency has grown from 25.1% in 2022 to 26.5%, with a target of 27% by 2025. The new Tiger Neo 3.0 module delivers up to 670W and brings several advantages:
High bifacial gain: Over 85%, making it ideal for reflective environments like deserts and rooftops.
Low degradation: Less than 1% power loss in the first year.
Enhanced low-light performance: Boosting output in mornings and evenings by up to 2.49%.
Field tests in countries like Japan, Italy, and China confirm its reliability in harsh weather. In Kagoshima, Japan, the modules delivered 7.1% more power per watt than competing n-type BC modules.
Economically, the module helps reduce system costs. In Saudi Arabia’s heat, BOS costs dropped, and LCOE improved by 4.73% for a 100MW setup. It’s also compatible with major inverters and O&M systems, and its anti-dust frame design cuts maintenance costs in dusty regions.
Looking ahead, Jinko aims to push efficiency even further, combining TOPCon with tandem cell designs to potentially surpass 32.5% efficiency in the future.
