Dr. Erkan Aydin delivers invited talk at MATSUS25 in Seville on the role of interface on the performance and stability of Earth and space PVs

March 5, 2025

Dr. Erkan Aydin was an invited speaker at the Materials for Sustainable Development Conference (MATSUS25), held from March 3–7, 2025, at the Meliá Sevilla Hotel in Seville, Spain. Organized by nanoGe, the conference brought together leading researchers in the field of sustainable materials and energy technologies.

Dr. Aydin's talk, titled "The Role of Interfaces in the Stability of Perovskite-Silicon Tandem Solar Cells: From Earth Applications to Space Use," highlighted the latest advancements in perovskite-based tandem solar cells for both terrestrial and extraterrestrial applications.

Over the past decade, tandem solar cells have achieved remarkable performance improvements, with power conversion efficiencies (PCEs) approaching 34%. In 2023, Dr. Aydin's research contributed to three record-breaking PCEs of 32.5%, 33.2%, and 33.7%, achieved through innovations in perovskite interfaces, alternative selective contacts, and transparent electrodes. His talk emphasized the critical role of interfaces in improving device efficiency, stability, and sustainability.

A key focus was on addressing stability challenges, particularly the impact of thermomechanical stresses and radiation sensitivity, which are crucial for space applications. Dr. Aydin presented systematic strategies to enhance the durability of dual-junction tandem solar cells, ensuring their viability for future Earth-based and extraterrestrial missions.

The MATSUS25 conference served as a platform to discuss research in sustainable energy technologies, reinforcing the importance of perovskite-silicon tandems in the transition toward a greener and more efficient solar energy future.
