Risen Energy's Vision for Sustainable Silver Reduction in HJT Technology

In the rapidly evolving photovoltaic sector, Risen Energy has taken a bold step forward with its strategy for minimizing silver content in HJT technology. This strategic move comes against a backdrop of discussions within the industry focused on reducing costs associated with silver paste and seeking innovative metallization materials. To delve deeper, we turn attention to Risen Energy's technical white paper, which provides critical insights into its roadmap for low-silver metallization paste development. This document serves not only as a framework for technological advancement but also offers practical lessons derived from extensive industry experience.

Strategic Vision and Comprehensive Planning

Recognizing the finite nature of silver reserves and the inherent volatility of prices, Risen Energy is adapting its production methodologies to ensure sustainable growth. Much like the historical shift from gold to copper in electronic circuitry, the company acknowledges that transitioning to cost-effective metallization alternatives is imperative for future progress. Risen Energy's approach transcends mere substitution; it embodies a systematic framework for implementation that evaluates prospective materials based on three core criteria:
1. Electrical Conductivity
2. Global Reserves
3. Market Stability

Upon thorough analysis, copper emerged as the most promising candidate due to its exceptional conductivity (5.96 × 10⁷ S/m), ample global reserves, and cost effectiveness.

Technological Pathway and Innovations

In its quest for innovation, Risen Energy has demonstrated a preference for low-silver paste, which encapsulates a cost-efficient metal core within a silver shell. This approach aligns seamlessly with existing production lines, allowing for rapid scalability without compromising the manufacturing process. In addition, the white paper shows that modules utilizing low-silver paste maintain a significantly reduced degradation rate, even after rigorous moisture and temperature cycle tests (DH and TC tests), with some exceeding the performance of traditional all-silver paste modules.

From Innovation to Mass Production

Over the past few years, Risen Energy's HJT products have been consistently and successfully produced on an industrial scale. Currently, the amount of pure silver consumed in Risen Energy's HJT cells has been impressively reduced to just 3.9 milligrams per watt—a figure that stands as a benchmark globally.

Reflections and Future Perspectives

The insights presented in the white paper underscore three foundational principles that guide Risen Energy's strategy:
1. Inherent Synergy Between HJT and Low-Silver Materials: The technological characteristics of HJT enable secure and efficient metallization innovations, particularly through low-temperature fabrication and bifacial efficiency.
2. Cost Reduction as a Value Multiplier: By weaving together material optimization with production excellence, Risen Energy achieves lower Levelized Cost of Energy (LCOE) and maximizes return on investment (ROI), maintaining reliability and performance.
3. Material Innovation as an Industry Catalyst: The ongoing reduction of silver consumption signifies not just cost savings but also a transformative shift within photovoltaic technology paradigms.

In conclusion, Risen Energy expresses gratitude to its clients and partners for their continued support and trust in the HJT technology. The company remains dedicated to its original goal of reducing costs while enhancing efficiency, thereby advancing the industrialization of HJT technology and contributing significantly to the global energy transition.
