Homerun finds modules retain 95% efficiency

Executive Summary

• Homerun Resources Inc.'s 100% owned subsidiary, Homerun Energy, announced a major technological milestone regarding its perovskite photovoltaic technology, following the publication of a peer-reviewed study in Nature Energy.
• The study demonstrates that large-area perovskite modules achieved high efficiency and exceptional operational durability, retaining more than 95% of initial efficiency after over 5,000 hours of continuous light soaking.
• This breakthrough validates the company's industrial roadmap for scalable, durable perovskite solar modules and strengthens the foundation for scaling manufacturing lines toward industrial deployment.

Key Details

• Publication: Peer-reviewed study published in Nature Energy titled "Co-crystal engineering of a two-dimensional perovskite phase for perovskite solar modules with improved efficiency and stability."
• Performance Metrics:
  • Modules retained >95% of initial efficiency after >5,000 hours of one-sun light soaking at maximum power point conditions.
  • Tested on 9.0-square-centimetre modules and 48-square-centimetre modules.
• Technical Approach: The research utilized a "co-crystal engineering" approach to improve long-term operational stability using 2-D perovskite interlayers, addressing key industry challenges regarding device durability.
• Team Involvement: Homerun Energy scientist Enrico Leonardi contributed to the multinational research team alongside authors including Aldo Di Carlo, Michael Gratzel, and others.
• Strategic Impact: The results support the "bankability" of the technology and validate the focus on industrialization-ready perovskite PV, specifically targeting lightweight, high-performance PV for built environments and energy systems.
• Company Context: Homerun Resources is developing a vertically integrated clean energy platform focusing on silica, solar (including a planned 1,000-tonne-per-day solar glass plant), energy storage, and AI-enabled energy solutions.

Notable Quotes

• "This Nature Energy publication validates the direction of our industrial perovskite road map: large-area modules that combine high efficiency with durability under real operating conditions," said Luca Sorbello, chief executive officer of Homerun Energy. "The demonstrated retention after extended full-sun light soaking is especially relevant to bankability discussions and strengthens the foundation for scaling our manufacturing line toward industrial deployment."
