On May 7, Gokin Solar made a striking debut at Intersolar Europe 2025 in Munich, showcasing its next-generation Back Contact (BC) solar modules. With a record-breaking 24.5% conversion efficiency, 685W mass-production power output, and minimalist aesthetic design, Gokin’s booth became a focal point for global clients and industry experts.
BC Technology Redefined: Where Efficiency Meets Elegance
Gokin’s BC modules redefine industry standards through three breakthroughs:
685W max power output and 24.5% module efficiency — setting new performance benchmarks.
Proprietary silicon wafers with tight resistivity distribution, superior impurity gettering, and enhanced mechanical strength, ensuring unmatched consistency and field reliability.
The modules embody "simplicity through innovation":
0BB (busbar-free) design eliminates front/rear gridlines for a seamless all-black appearance.
Ideal for diverse applications, from commercial rooftops to residential installations.
BC technology is the future of photovoltaics," said Allen Xu，Director & Head of Overseas Business, Gokin Solar"As an integrated expert, we’ve achieved full in-house control of the BC value chain. We’re accelerating mass production to empower the global energy transition."
TÜV Rheinland Certification: Proof of Excellence
Gokin Solar's BC modules have achieved dual certification from TÜV Rheinland, receiving both the IEC 61215/IEC 61730 certification. During the event, Lukas Jakisch, VP of Solar & Commercial Products at TÜV Rheinland Europe, presented the certification and praised:"Even under shading from trees, dust, or bird droppings, Gokin’s modules maintain exceptional generation efficiency–delivering higher long-term ROI and raising the industry bar."
The certification underscores:
Gokin’s global leadership in BC technology.
Its rigorous commitment to reliability and quality.
Shading and hot spots are critical threats to PV system safety. Gokin’s diode-like bypass structure minimizes power loss, prevents localized overheating, and ensures stable energy yield – maximizing project returns.
