Become an actor of the Energy Transition by joining a team driven by innovation and impact to address today’s most decisive challenges.
IPVF – Institut Photovoltaïque d’Île-de-France, is a global Research, Innovation and Education center, which mission is to accelerate energy transition through science & technology.
Gathering industrial PV leaders (EDF, Total, Air Liquide, Horiba and Riber) and world-renowned academic research teams (CNRS, Ecole Polytechnique), multi-disciplinary and international IPVF teams conduct research for clean energy technologies.
IPVF at a glance:
Solar cells made of III-V materials present the best efficiencies among currently available technologies, up to 46% under concentration. However, this technology suffers from high cost, significantly higher than mainstream silicon modules. The major part of this cost (about 80% to 90%) lies in the III-V substrates needed for the growth of monocrystalline materials with high quality.
We propose to explore a new strategy to reuse the substrate for several consecutive growths, in order to drastically reduce its cost contribution. The main goal is to modify the surface of the III-V substrate, so that the fabricated III-V layers can be easily detached, leaving a clean surface suitable for subsequent layer fabrication. A promising route for surface modification, emerging in recent high impact studies and called remote epitaxy, consists in depositing graphene layers on top of the substrate. The complete process is depicted in the figure below.
The candidate will directly report to the Deputy Programs Director of IPVF.
She/he will integrate a dynamic and talented team driven by innovation and results.
The objectives of the PhD are twofold:
This work will be done in close collaboration with the Center for Nanoscience and Nanotechnologies (C2N, SUNLIT team). It includes several methods of fabrication (graphene by CVD, III-V by MBE) and characterization (luminescence, SEM, TEM).
She/he will work in close relationship with highly qualified scientists, specialized in III-V materials and nanofabrication. This environment gives the PhD candidate many opportunities to tackle this project challenge and gain experience.
