NINGBO, China, March 9, 2026 /PRNewswire/ — Recent discussions within the photovoltaic industry have intensified around reducing silver paste costs and developing innovative metallization materials. In this context, we revisit Risen Energy’s technical white paper—White Paper of HJT Hyper-ion Products: Development and Application of Low-Silver Metallization Paste—to reexamine the company’s early strategic insights, experimental validations, and foundational preparations. This retrospective analysis aims to provide industry peers with practical perspectives derived from hands-on experience.
I. Foresight and Systematic Planning: Beyond Mere Substitution
Confronting silver’s limited reserves and price volatility, Risen Energy recognized that adopting low-cost metal alternatives was imperative for sustainable growth—akin to the historical transition from gold to copper interconnects in integrated circuits. The company’s approach extended beyond conceptual substitution to systematic implementation:
Comprehensive Material Selection: Risen Energy evaluated candidate metals (e.g., copper, aluminum, zinc, nickel) based on three criteria: electrical conductivity, global reserves, and market stability. Copper emerged as a prime candidate due to its high conductivity (5.96×10⁷ S/m), ample reserves, and cost-effectiveness.
Strategic Technology Pathway: While electroplating offers a silver-free alternative, Risen Energy prioritized low-silver-content paste—where a silver shell encapsulates low-cost metal cores—for its compatibility with existing production lines and rapid scalability.
Rigorous Reliability Validation: The white paper shows that modules employing low-silver-content pastes demonstrate excellent degradation rate…
