Risen Energy's Vision for Low-Silver HJT Technology

In recent years, the photovoltaic industry has witnessed fervent discussions centered around reducing silver paste costs and developing innovative metallization materials. Risen Energy, a prominent player in this space, has taken proactive steps towards achieving sustainable growth through strategic shifts in their approach to technology.

The company's White Paper titled 'Development and Application of Low-Silver Metallization Paste' sheds light on their early strategic insights, experimental validations, and foundational preparations aimed at fostering practical advancements within the industry.

Strategic Planning for Sustainable Growth

Understanding the constraints of silver availability and its price volatility, Risen Energy has recognized the need to adopt cost-effective metal alternatives. Drawing parallels with the historical transition from gold to copper interconnects in integrated circuits, the company has formulated a strategy that goes beyond mere conceptual substitutions. Instead, their focus encompasses comprehensive material implementation strategies.

Risen Energy evaluated various candidate metals, including copper, aluminum, zinc, and nickel, based on three key criteria: electrical conductivity, global availability, and market stability. Among these, copper emerged as the most viable option due to its excellent conductivity, abundant supplies, and cost effectiveness.

Embracing Low-Silver Paste Technology

While silver-free alternatives like galvanic plating are in consideration, Risen Energy has prioritized low-silver paste technology. This method employs a silver coating around a less expensive metallic core, ensuring compatibility with existing production lines and allowing rapid scalability.

The rigorous reliability testing outlined in the white paper demonstrates that modules utilizing low-silver pastes exhibit exceptional performance, particularly in terms of degradation rates under demanding conditions such as damp heat (DH) and thermal cycling (TC) tests. In certain scenarios, these modules even outperform those employing conventional pure silver pastes, showcasing comparable energy output.

Moving from Innovation to Mass Production

Risen Energy's HJT products have reached stable mass production levels across various manufacturing lines over the past few years. Currently, the consumption of pure silver in the heterojunction technology (HJT) articles produced by the company has been reduced to a remarkable 3.9 milligrams per watt (mg/W), placing it at the forefront of global metrics in terms of efficiency.

Core Principles Guiding Future Endeavors

This strategy underscores three fundamental principles:

1. Natural Synergy: The intrinsic compatibility of HJT technology with low-silver materials, low-temperature manufacturing processes, and outstanding passivation provides a robust platform for secure and efficient metallization innovations.

2. Cost Reduction as Value Multiplier: By integrating material optimization alongside process excellence, Risen Energy is positioned to achieve lower levelized costs of electricity (LCOE) and enhanced return on investment (ROI), all without compromising on reliability or performance.

3. Material Innovations as Industry Catalysts: The reduction in silver usage transcends mere cost savings, signifying a paradigm shift towards greater sustainability within photovoltaic technologies.

Risen Energy extends its gratitude to all customers and partners for their ongoing trust in the HJT technology. The company remains committed to advancing its founding goals of reducing costs and enhancing efficiency, facilitating the implementation of HJT technology at scale, and significantly contributing to the global energy transition.

Conclusion

In summary, Risen Energy is not merely adapting to industry trends but is actively shaping the future of photovoltaics by championing low-silver metallization technologies. Their strategic foresight and commitment to innovation set a compelling example for the entire industry in pursuit of cost-effective and sustainable energy solutions.
