Exploring the Frontiers of Photovoltaic Printing Innovation | Autowell Delivers Keynote Speech at MIW 2025 in Germany
OCT. 23, 2025
At the Metallization & Interconnection Workshop (MIW) 2025, held in Berlin this October, Dr. Ning Chen, Director of Autowell Laboratory, was invited to deliver a speech titled “Printing Technologies for PV Beyond Metal Pastes and Stainless Steel Screens.” In his presentation, Dr. Chen shared Autowell’s latest breakthroughs and research progress in the field of advanced photovoltaic (PV) printing technologies.
About MIW 2025
The Metallization & Interconnection Workshop (MIW) is a globally recognized conference dedicated to cell metallization and interconnection technologies in the photovoltaic industry. The event brings together leading research institutions and industry experts from around the world to discuss critical topics such as electrode performance enhancement, process optimization, and material cost reduction.As a key international platform, MIW is regarded as a trendsetter for next-generation metallization and interconnection solutions. Each year, it fosters deep collaboration between academia and industry through keynote presentations, technical forums, and exhibitions—accelerating innovation and industrial advancement in PV manufacturing.
Autowell’s Vision for the Future of PV Printing
In his speech, Dr. Chen emphasized that although the global price of PV modules continues to decline, the costs of key materials such as silver paste and printing screens remain high, posing major challenges to cost reduction and efficiency improvement across the industry.To address this, Autowell is actively advancing "silver-free” and "non-metal” printing technologies, aiming to drive PV printing toward a more efficient, compatible, and sustainable future.
Breakthroughs Shared at MIW 2025
During the conference, Dr. Chen presented several of Autowell’s latest innovations, including advancements in insulating adhesive and solder paste printing, 0BB adhesive printing, low-/non-silver metal paste printing, and mass production of steel-screen printing technologies.Among these, the Autowell xBC Cell Printing Line drew significant attention. Designed for automated printing of insulating adhesive and solder paste on BC cells before module assembly, this solution delivers three key advantages:
- High Productivity
- Strong Compatibility
- Exceptional Reliability
The introduction of the xBC Cell Printing Line represents a critical step toward high-quality module production. It helps prevent short circuits between positive and negative electrodes, improves soldering quality, and significantly enhances overall yield and long-term module reliability.
Currently, the xBC Cell Printing Line is being adopted by a growing number of customers worldwide, earning strong recognition and repeat orders for its outstanding performance and proven stability.
