Outlook on Global PV Silver Paste Demand and Technology Trends [SMM Silver Conference]

On May 16, at the 2025 SMM (6th) Silver Industry Chain Innovation Conference, hosted by SMM Information & Technology Co., Ltd. (SMM) and co-organized by Ningbo Haoshun Precious Metals Co., Ltd. and Quanda New Materials (Ningbo) Co., Ltd., with strong support from sponsor organizations including Fujian Zijin Precious Metals Materials Co., Ltd., Huizhou Yian Precious Metals Co., Ltd., Jiangsu Jiangshan Pharmaceutical Co., Ltd., Zhengzhou Jinquan Mining and Metallurgical Equipment Co., Ltd., Hunan Shengyin New Materials Co., Ltd., Zhejiang Weida Precious Metals Powder Materials Co., Ltd., Guangxi Zhongma Zhonglianjin Cross-border E-commerce Co., Ltd., Suzhou Xinghan New Materials Technology Co., Ltd., Yongxing Zhongsheng Environmental Protection Technology Co., Ltd., IKOI S.p.A, Hunan Zhengming Environmental Protection Co., Ltd., Kunshan Hongfutai Environmental Protection Technology Co., Ltd., and Shandong Humon Smelting Co., Ltd., Miao Cheng, the Marketing Manager of Changzhou Fusion New Materials Co., Ltd., shared insights on the topic of "Global PV Silver Demand and Technology Trends Outlook."

PV Market - Slowdown in Installation Growth

PV Market - Technological Changes and Trends in Silver Paste Consumption

He analyzed the market share estimates for various technologies such as PERC, TopCon, HJT, xBC, and others, as well as the average silver consumption per watt for global PV silver paste.

Global Silver Production and PV Silver Paste Consumption

He discussed these topics in conjunction with the changes in SHFE silver prices from 2020 to 2025 and an analysis of silver supply and demand.

Forecast for Total Global PV Silver Paste Demand in 2025

He also shared Fusion New Materials' cost-reduction strategies in metallization for the new era of PV.

Metallization - The Imbalance Among Three Key Factors

He discussed cost reduction, efficiency improvement, and reliability in PV cells, stating that as specific consumption decreases to a certain level, the risk of reliability issues increases exponentially!

Impact and Solutions of Paste Formulations on Acetic Acid-Related Issues

Highly Corrosion-Resistant Paste

Low Silver Consumption → Strong Demand for Acetic Acid-Resistant Systems

Regulating powder interactions to optimize the material's coefficient of thermal expansion and acid resistance; reducing inorganic corrosion of silicon and the thickness of the glass layer; designing dense powder packing to reduce electrode void density.

High-Resistance Dense Grid Technology - Efficiency Improvement + Specific Consumption Reduction ↓ + Reliability Increase ↑

•Contact Conductivity: Structural control of the Ag-Si interdiffusion layer.

•Achieving Both Specific Consumption Reduction and Efficiency: Narrow line width + full-aperture stencil combined with super-dense grid.

•Balancing Reliability and Specific Consumption: Further improving acetic acid resistance to provide a paste foundation for both single-glass and dual-glass products.

Trend of Thinner Lines in PV Pastes

Cost-Reduction Benefits of Silver Paste Brought by Full-Aperture Screens

Summary: The promotion of full-aperture screens has reduced non-silicon costs by 4-7%.

It also introduced the development history of silver-coated copper paste solutions, the development direction of silver-coated copper paste, the market progress of copper paste, and the development history of Juhe.
