Templates035 R&D division announces that our next-generation TOPCon solar cells have achieved a certified conversion efficiency of 26.2% on full-size commercial wafers (182mm M10), verified by Fraunhofer ISE CalLab, surpassing the previous industry record and approaching the theoretical single-junction silicon limit.

Technology Breakthrough

• Certified efficiency: 26.2% on 182mm M10 wafer (Fraunhofer ISE CalLab verified)
• Key innovation: Poly-Si/SiOx passivated contact with ultra-thin (<1.2nm) tunnel oxide
• Metallization: LECO (Laser-Enhanced Contact Opening) with fine-line silver paste (<18μm)
• Passivation: Al2O3/SiNx rear surface with field-effect passivation achieving J0 <2 fA/cm²

Path to Mass Production

• Pilot line producing 10,000 cells/day at 25.8% average efficiency
• Full production line (GW-scale) conversion scheduled for H2 2026
• Expected module-level efficiency: 23.5-24.0% (700W+ panel rating)
• Manufacturing cost premium: <5% versus current generation TOPCon

Industry Significance

This achievement narrows the gap to heterojunction (HJT) and perovskite-silicon tandem technologies while maintaining TOPCon's significant manufacturing cost advantage and compatibility with existing PERC production equipment through retrofit upgrades.
