Education: PhD in Materials science, Physics (or related)
Salary: Salary grid



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, TotalEnergies, Air Liquide, Horiba and Riber) and world-renowned academic research organizations (CNRS, Ecole Polytechnique), multi-disciplinary and international IPVF teams conduct research for clean energy technologies. Supported by the French State, IPVF is labelled Institute for Energy Transition (ITE).


IPVF at a glance:

     – An ambitious Scientific and Technological Program (6 programs divided in 24 work packages): from tandem solar cell technologies to economy & market assessment, state-of-the art characterization, photocatalysis and breakthrough concepts.

     – A state-of-the-art technological platform (8,000m²): more than 100 cutting-edge equipments worth €30M, located in cleanrooms (advanced characterization, materials deposition, prototypes for fabrication, modelling…).

     – A high-standard Education program (M.S. and PhD students).







IPVF is looking for a Research Engineer to work on III-V solar cells for high-efficiency and low-cost photovoltaics. The project will be carried out in close collaboration with the Center for Nanoscience and Nanotechnologies (C2N-CNRS, SUNLIT team).

Attached to the III-V on Silicon tandem program, the engineer will be in charge of the MBE platform and will also be involved in the research work of the III-V project.

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 (https://doi.org/10.1002/pip.3249), 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).

The candidate will benefit from a multidisciplinary environment, IPVF expertise and have access to IPVF and C2N unique capabilities. He will directly report to the Programs Deputy Director of IPVF and will integrate a dynamic and talented team driven by innovation and results.








Within the framework of our growth, we want to reinforce our Programs Direction with the recruitment of a Research Engineer to join our “III-V/Si tandem devices” program.


The Research Engineer will participate in the research work of the program, and will ensure:
– a support on the different projects using MBE,
– involvement in the III-V planar workpackages,
– involvement in III-V layer transfer tasks,
training on III-V cell manufacturing processes, when needed,
optimization of MBE and growth processes,
fabrication of III-V layers and devices.


She/He will also be in charge of the MBE platform, the tasks will consist of:
– plan, follow and perform the maintenance of the MBE,
– set-up systematic growth procedures for the different users,
– set-up a systematic monitoring of the performance of the framework (through regular measurement of KPIs to be determined with the users),
– maintain a body of documentation (risk analysis, operating instructions) and technical monitoring of the equipment (workbooks, monitoring of indicators),
training of new epitaxial users,
– propose equipment upgrades and safety improvements,
purchasing supplies and monitoring stocks, especially sources and substrates.
