HOMERUN RESOURCES INC. 100% OWNED SUBSIDIARY HOMERUN ENERGY REACHES STABILITY BREAKTHROUGH IN LARGE-AREA PEROVSKITE MODULES RETAINING MORE THAN 95% EFFICIENCY AFTER >5000 HOURS

Homerun Energy SRL, a 100-per-cent-owned subsidiary of Homerun Resources Inc., has reached a major milestone for its perovskite photovoltaic technology following the publication of a peer-reviewed study in Nature Energy describing a scalable material and interface approach that delivers both high efficiency and strong operational durability in large-area perovskite solar modules.

The Nature Energy article, "Co-crystal engineering of a two-dimensional perovskite phase for perovskite solar modules with improved efficiency and stability," reports a significant improvement of long-term operational stability while maintaining high performance. The research team reports 9.0-square-centimetre modules and 48-square-centimetre modules that retained more than 95 per cent of initial efficiency after greater than 5,000 hours of one sun light soaking at maximum power point conditions.

Homerun Energy notes that its scientist, Enrico Leonardi, contributed to the multinational team alongside the other authors, including Aldo Di Carlo, Michael Gratzel, Narges Yaghoobi Nia, Mahmoud Zendehdel, Barbara Paci, Jiayi Xu, Marco Di Giovannantonio, Amanda Generosi, Cong Liu, Giorgio Contini and Marco Guaragno, work that aligns directly with Homerun Energy's focus on industrialization-ready perovskite PV.

"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."

According to the study, the co-crystal engineering approach addresses a key industry challenge: improving the long-term operational stability of perovskite devices that use 2-D perovskite interlayers, enabling robust performance in both cells and modules.

Homerun Energy plans to leverage these insights to accelerate its progress toward high-throughput production and industrial applications where lightweight, high performance PV can unlock new use cases across built environments and energy systems.
