ISFH at EU PVSEC 2025

ISFH at EU PVSEC 2025: Strong Presence with Innovative Contributions to Photovoltaics Research

This year, ISFH will once again participate in the European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC 2025), held in Bilbao, Spain. The EU PVSEC is Europe’s leading conference in the field of photovoltaics. From 22 to 25 September 2025, our scientists will present the latest research findings and pioneering technologies for the next generation of solar energy.

The ISFH contributions reflect the thematic diversity and scientific excellence of our research, ranging from innovative cell concepts and new module designs to long-lasting material systems.
