Géraud Delport

Géraud Delport is a CNRS permanent researcher at the IPVF Laboratory in Palaiseau, France, specializing in optical and optoelectronic properties of hybrid perovskite materials. His research focuses on cryogenic spectroscopy of quantum electronic effects (excitons, polarons), lead-free perovskites, and thin-film optoelectronic devices including photovoltaics and photodetectors. He maintains extensive collaborations with LUMIN Laboratory Saclay, GEMAC Laboratory, IRCP Lab Paris, FOTON and ISCR Rennes, and CEA LITEN.

His academic background includes:

• Post-doctorate (2018-2020) at Cavendish Laboratory, Cambridge University in Samuel Stranks' team
• Post-doctorate (2017-2018) with CNRS contract at Université Paris Saclay
• PhD (2013-2016) at ENS Paris Saclay in Nanophotonics group of Aimé Cotton/LUMIN laboratory under Prof. Jean Sébastien Lauret
• Physics studies (2009-2013) at ENS Cachan

Dr. Delport's research bridges fundamental physics with practical applications in optoelectronics. He specializes in time-resolved photoluminescence spectroscopy to investigate exciton dynamics and charge carrier behavior in 2D/3D perovskite structures. His work spans from carbon nanotube photophysics (earlier career) to current leadership in gold-based and lead-free perovskite development, with emphasis on correlating structural properties with optoelectronic performance. Recent work explores cryogenic spectroscopy techniques to understand quantum electronic phenomena in novel semiconductor materials.

Analysis of his publication record shows increasing focus on environmentally sustainable perovskite alternatives, particularly gold-based systems, with significant contributions to understanding radiative efficiency limitations and structural-optical property relationships. His research demonstrates progression from fundamental nanoscale characterization to device-oriented applications, with recent papers addressing challenges in photovoltaic efficiency and material stability.

Dr. Delport's research is supported by competitive funding including:

• French ANR young researcher grant "POETESSE"
• "Photothermal techniques to study thin films semiconductors" (MIRADOR project)
• "Photodetector based on lead-free perovskite materials"
• CABLESOLAR Project on "tethered altitude balloons with flexible solar panels"

As a research supervisor, he actively recruits doctoral and postdoctoral candidates for projects in optical spectroscopy and solid-state chemistry, with current openings for thin-film deposition research and lead-free perovskite synthesis. His collaborative approach spans multiple French research institutions, creating an integrated ecosystem for advancing perovskite-based optoelectronic technologies from fundamental science to practical applications.
