The “Institut Photovoltaïque d’Île-de-France” IPVF aims at becoming one of the main global research, innovation and education center in the field of photovoltaic solar energy. Composed with international well-known industrials, leading in PV industry (EDF, Total, Air Liquide, Horiba and Riber) and academic research teams (CNRS, Ecole Polytechnique), IPVF wants to increase performances and competitiveness of PV solar cells and develop new breakthrough technologies thanks to:

  • A research program : 5 programs and 12 projects
  • Experimental laboratories open to PV actors : more than 70 state-of-the-art tools, in a dedicated IPVF building
  • Education program with a master and PhD students



The Ile-de-France Photovoltaic Institute (IPVF) and the Center for Nanosciences and Nanotechnologies (C2N-CNRS, SUNLIT team) are seeking several postdoctoral researchers to work on III-V solar cells for high-efficiency and low-cost photovoltaics. The projects will be carried out in close collaboration between the two institutes.

Our team has recently demonstrated ultrathin (200 nm) GaAs solar cells with a record efficiency of nearly 20% using efficient light trapping, in collaboration with Fraunhofer ISE (published in Nature Energy, 2019, https://www.nature.com/articles/s41560-019-0434-y). We have also developed state-of-the-art, wide-bandgap (1.7-1.8eV) solar cells made of AlGaAs for integration in III-V/Si tandem solar cells (to be published), and we have recorded important advances in nanowire-based solar cells (https://sunlit-team.eu/news/advances-in-nanowires-for-pv/). These results have opened new opportunities for the development of low-cost and high-efficiency photovoltaics based on tandem III-V/Si architectures and advanced concepts (hot-carrier solar cells in particular).



Several postdoc positions are currently available in order to strengthen these activities. Please contact us for more details. The post-doc will benefit from a multidisciplinary environment and will have access to the unique, complementary clean-room facilities at IPVF and C2N including state-of-the-art epitaxy, nanofabrication and characterization tools.

The ideal candidate will have a PhD in material science, semiconductor physics or related. Previous experience in nanofabrication, epitaxy of III-V semiconductors, photovoltaics is desirable but not essential. More information and recent publications from the C2N team can be found here: http://sunlit-team.eu/

The positions will start immediately for a duration of 18 months. Applications will be reviewed as received until the position is filled.
