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

Linear interactive printing system with cycle time ≤ 0.8s

• Strong Compatibility

Supports mainstream and next-generation N-type technologies; adaptable to multiple cell sizes and materials with optimized drying processes

• Exceptional Reliability

Industry-leading precision and print shaping quality, ensuring high-performance and consistency

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.

Looking Ahead

Autowell will continue to strengthen collaboration with global partners across academia, research, and industry, driving the advancement of high-efficiency solar cell manufacturing toward greater intelligence and sustainability.
