IPVF – Team
Photovoltaic Institute of Île-de-France
My research team at the Institut Photovoltaïque d’Île-de-France (IPVF) focuses on enhancing the performance of photovoltaic devices by developing various materials. Our work covers established solar technologies such as silicon and GaAs, as well as emerging materials like thin films of chalcogenides and hybrid perovskites. We also explore innovative, high-efficiency concepts such as tandem solar cells and hot carrier solar cells, along with promising materials like lead-free double perovskites. Our team specializes in characterizing and modeling the physical phenomena related to photovoltaic materials, using advanced optical techniques to measure transport properties, defects, and interfaces. We collaborate with other teams at the IPVF (industrial partners) and international experts to develop new approaches and improve solar cell performance, particularly by studying the fundamental properties of
polycrystalline thin films and single crystals of perovskites.
