Heterojunction Technology: The Ultimate Solution to Photovoltaic Patent Dilemma

After decades of development, Risen Energy has obtained great achievements and become the "Patent Moat". Risen Energy, with its Global Photovoltaic Research Institute, has launched the Next-Gen Technology Revolution, which will greatly benefit the whole industry.

I. Patent Wars in the Photovoltaic Industry: The Sword of Damocles Hanging Over TOPCon

As global photovoltaic installations surpass the 400GW, a silent war is intensifying, where patent litigation has become a new weapon to stifle technological innovation.

The numbers paint a striking picture:

- Patent disputes now span China, the U.S., Europe, Japan, and Australia, with lawsuits following a pattern of domestic filings coupled with overseas counterattacks, forming a complex network of patent offensives and defenses among leading enterprises.

- First Solar, leveraging its TOPCon structure patents, has filed five lawsuits in Germany, India, and Australia, each seeking over $100 million in damages.

Beneath these legal battles lies a harsh reality: the golden era of a technology can be eclipsed by the shadow of patents. This dilemma underscores a crucial lesson: when technological roadmaps are deeply entwined with restrictive patent portfolios, any capacity expansion risks becoming bargaining chips in the courtroom.

II. Heterojunction (HJT): The "Ark" Navigating the Patent Minefield

Amid this patent chaos, Risen Energy's Hyper-ion HJT technology has charted a distinct path forward.

1. Patent Safety Zone: Seizing Opportunity with Foresight

- Unique Time Window: The foundational HJT patents originally held by Sanyo expired globally in 2023, ushering in an open-source era for the core technology.

- Independent Patent Matrix: Risen Energy has built a comprehensive patent portfolio, covering over 500 patents across critical innovations, including busbar-free technology and Hyper-Link Low-Temperature Stress-Free Interconnection Technology.

From equipment localization to process and material development, HJT at Risen Energy is fully de-risked from external dependencies. Unlike TOPCon, which is caught in a patent battlefield, Risen Energy's HJT production lines are shielded by a "patent moat."

2. Technology Generation Gap: The Efficiency-Cost "Scissors Effect"

- Efficiency Breakthrough: Hyper-ion HJT cells have achieved an average mass-production efficiency of 26.2%, with module power reaching 730Wp, and continue to climb following a clear technology roadmap.

- Accelerated Cost Reduction: Silver consumption has dropped to 5mg/W (37.5% lower than TOPCon), while busbar-free technology has driven metallization costs below mainstream products.

- Scenario Dominance: Delivers over 6% higher energy yield in high-temperature, high-reflectivity environments, ideal for emerging markets such as the Middle East and Southeast Asia.

Critically, HJT's unique combination of TCO film, symmetric structure, and low-temperature processing makes it the perfect foundation for perovskite tandem integration-the key to unlocking 30%+ efficiency.

III. Strategy of Risen Energy: A Double Helix Approach to Patent & Technology

Risen Energy has forged a clear path forward: leveraging patents to define industry standards and driving technological evolution to reshape competition.

1. Three-Tier Patent Defense System

- Shield Layer: Collaborate with industry leaders to form an HJT Technology Alliance, ensuring a unified front.

- Sword Layer: Proactively secure overseas patents for core HJT technology to maintain a strategic edge.

- Ecosystem Layer: Co-develop critical equipments with SMEs to expand the HJT ecosystem.

2. Building a Self-Sustaining Technology-Market Cycle

- Standard-Setting Authority: Leading research on HJT metastability and driving the development of stabilization standards, securing control over technological benchmarks.

- Supply Chain Synergy: Partner with suppliers through "IP non-infringement declarations", eliminating legal concerns for customers.

Risen Energy's strategy is not just a technological revolution but a redefinition of industrial survival. In the midst of patent wars, Risen Energy chooses openness over restriction, innovation over monopoly, and collaboration over competition.

Conclusion

The future of photovoltaics does not belong to those who crawl through patent minefields, but to pioneers who dare to chart new territories. HJT technology is the beacon Risen Energy has ignited for the industry. When the Damocles sword of patents falls, the HJT legion-armed with shields of patents and spears of innovation-will lead the dawn of a new photovoltaic era.
