bifi PV 2025
Global BC Tech Innovation Summit
Once, BC was a solitary path of exploration; today, it has become the unstoppable mainstream of the photovoltaic revolution. AIKO, evolving from the “lone pioneer of BC” to “a leading force in the BC era,”
has witnessed the dawn of this technology’s immense value alongside our esteemed industry peers. Now, to write the next chapter, we gather once more.
As a beacon for global PV technology, the Global BC Technology Innovation Summit & the 14th Bifi PV Workshop will be grandly held on November 24-25, 2025, in the innovation hub of Yiwu, Zhejiang, China.
This summit is proudly co-hosted again by AIKO and our strategic partner, ISC Konstanz of Germany. The event will unite over 500 global leaders, including top minds from authoritative institutions like, TüV Rheinland, and PVEL; world-leading universities such as TU Delft and UNSW; and key innovators from across the industry value chain, to collectively shape the future blueprint of BC technology. This is more than a technical conference; it is your pinnacle dialogue with the global definers of photovoltaics. AIKO cordially invites you to join this landmark occasion and co-create the future.
Event Highlights
8+ Hot Topics: A 360° View of BC Technology
Dive deep into the entire lifecycle of Back-Contact (BC) technology. Our agenda covers everything from foundational silicon materials and advanced cell techniques to module mass production and power plant system design. We’re bridging the gap between upstream and downstream players to build a powerful, self-sustaining ecosystem of innovation and industrial collaboration.
A Summit of 500+ Global Minds Join an exclusive gathering of the world’s leading technical experts. We are proud to host luminaries from renowned institutions like TüV Rheinland, and PVEL; top academic minds from TU Delft (Netherlands) and UNSW (Australia); and industry pioneers from every corner of the photovoltaic value chain. Together, we will explore the next frontier of BC technology breakthroughs.
From Theory to Reality: An Immersive Experience Go beyond the conference room with an exclusive tour of AIKO’s state-of-the-art Smart Factory in Yiwu. You will witness the ABC module production line in full operation, observe its real-world performance, and experience firsthand the technology’s complete journey from the lab to mass production (“from R&D to fab”).
