JinkoSolar Breaks Solar Efficiency Record with 27.02% TOPCon Cell

JinkoSolar, a global leader in solar panel production, has achieved a world-record 27.02% efficiency for its n-type TOPCon solar cell—surpassing previous milestones and accelerating the industry’s push toward ultra-high-performance photovoltaics.

Key Breakthroughs

✅ Cell Efficiency: 27.02% (certified by China’s NPVM)
✅ Module Efficiency: 25.58% (certified by TÜV SÜD)
✅ Technology: Laser-assisted metallization, advanced passivation, and localized absorption contacts
✅ Future Target: Beyond 28% by 2028

Why This Record Matters

1. Pushing the Limits of Solar Efficiency

• Previous record (Oct 2022): 26.1%

• New milestone (2025): 27.02% (a ~1% absolute jump in less than 3 years)

• **Mass production modules now hit 24.8% efficiency (670W output)

2. How JinkoSolar Achieved This

🔹 Laser-assisted metallization – Reduces electrical losses
🔹 Premium emitter passivation – Minimizes electron recombination
🔹 Localized absorption contacts – Enhances light capture

3. Real-World Impact

• Higher efficiency = more power per square meter (reducing land use & costs)

• Bifacial factor up to 85% – Boosts energy yield in reflective environments

• **Supports global transition to ultra-high-efficiency solar farms

JinkoSolar’s TOPCon Roadmap

🚀 2025 Goal: 50 GW TOPCon production capacity (40% factory upgrades this year)
🚀 2028 Target: Beyond 28% cell efficiency

Industry Implications

🌍 TOPCon now firmly ahead of PERC as the dominant high-efficiency tech
🌍 Pressure on competitors (LONGi, Trina, JA Solar) to match or exceed
🌍 **Accelerates solar’s cost-per-watt decline, making renewables even more competitive

Final Takeaway

JinkoSolar’s 27.02% record proves that TOPCon is the future of solar—delivering unmatched efficiency gains while moving closer to the theoretical limits of silicon PV. With mass production scaling rapidly, expect even higher-performance panels in the coming years.
