Perrine Carroy studied materials science and engineering at the National Institute of Applied Sciences (INSA) in Lyon. She joined CEA-INES in 2012, after having worked 3 years in the R&D team of the former PV equipment supplier Oerlikon Solar. At CEA-INES, she worked for 9 years on silicon heterojunction solar cells, focusing on transparent conductive oxides. In 2021, she joined the Laboratory for Tandem Cells that focuses on perovskite/Si tandem devices. She is fond of collaborative research and after having been involved in many European or French funded research projects as participant or WP leader, she now coordinates the Horizon Europe project NEXUS that focuses on the development of high efficiency sustainable perovskite/Si tandem devices.

HE Project NEXUS: Overview of the Results Achieved During the 1st Period

NEXUS aims to develop 2-terminal perovskite-Si tandem solar cells with power conversion efficiencies >33% (modules >30%) and stabilities comparable to state-of-the-art single junction Silicon PV modules. In addition, NEXUS will achieve these challenging targets using an eco-design approach: employing solvent-free perovskite deposition, reducing critical elements, demonstrating circularity and recyclability, showcasing simple manufacturing processes, with the overall goal of creating a viable economic pathway for the European commercialization of this sustainable technology. The presentation will highlight the results obtained during the first half of the project and provide an overview of the progress of the project towards its scientific, economic and socio-environmental objectives.
