HEPAFLEX is a European research project focused on developing high-efficiency, flexible perovskite solar cells through sustainable materials and scalable, green processing methods. By combining innovative, high-throughput fabrication techniques with durable flexible designs, HEPAFLEX aims to extend device lifetime and deliver large-area, efficient solar cells for diverse applications.
Flexible. Sustainable. Scalable.
The global demand for clean, adaptable energy solutions is rapidly increasing, driving the need for photovoltaic technologies that are both efficient and environmentally sustainable. While halide perovskites have shown exceptional promise at the laboratory scale, challenges remain in scaling their production safely and sustainably. HEPAFLEX addresses this gap by developing flexible perovskite solar cells using green materials and high-throughput processes—bridging the divide between innovation and real-world implementation.
HEPAFLEX envisions a solar future that is flexible, sustainable, and accessible. Our mission is to create scalable perovskite technologies using green materials and fast, efficient manufacturing.
Flexible and adaptable solar cells — High-throughput production techniques for industrial scalability — Eco-friendly processes replacing toxic solvents and heavy energy use — Long-lasting devices designed for extended operational lifetimes — Integration of recycling and safety features to ensure circularity.
HEPAFLEX aims to redesign how solar cells are made and used. We focus on flexible substrates, sustainable chemistry, and upscalable techniques. The project seeks to cut both costs and environmental impact, while extending the lifespan of traditional rigid power modules beyond 25 years. The project also enhances technology safety by incorporating Pb-sequestration additive active sealants, which are seamlessly integrated with recycling methods to enable responsible material reuse. Ultimately, we support the EU’s green transition with cutting-edge photovoltaic innovation.
