Dr. Erkan Aydin Delivered Keynote at EcoMat Conference in Istanbul on Tandem Solar Cells for Earth and Space Use

July 30, 2025

Dr. Erkan Aydin delivered a keynote lecture at the EcoMat Conference in Istanbul, presenting on “The Role of Interfaces in the Stability of Perovskite–Silicon Tandem Solar Cells: From Earth Applications to Space Use.”

In his talk, Dr. Aydin highlighted how interface engineering has been central to achieving record-breaking power conversion efficiencies of up to 33.7% in monolithic perovskite–silicon tandem solar cells. He discussed strategies such as dielectric interlayers, advanced recombination junctions, alternative hole-selective contacts, and sustainable transparent electrodes with reduced indium content.

He also addressed the role of interfaces during encapsulation, where thermomechanical stresses can drive degradation, emphasizing the importance of interfacial strength for long-term stability. Finally, Dr. Aydin explored the challenges and prospects of deploying tandem solar cells in space, particularly considering radiation sensitivity and extreme environmental conditions.

This keynote reflected the latest advancements from his ERC-funded INPERSPACE project and ongoing collaborations, aiming to extend the reach of tandem photovoltaic technology from terrestrial to extraterrestrial applications.
