IPVF in brief

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.

Supported by the French State, IPVF is labelled Institute for Energy Transition (ITE).

IPVF at a glance:

  • An ambitious Scientific and Technological Program: from tandem solar cell technologies to economy & market assessment, state-of-the art characterization, photocatalysis and concepts breakthrough.
  • A state-of-the-art technological platform: more than 100 tools, located in cleanrooms (advanced characterization, materials deposition, prototypes for fabrication, modelling…).
  • A high-standard Education program (M.S. and PhD students).

Job context

In the context of the advanced characterization project, the IPVF characterization team aims to develop new characterization techniques, several of them based upon photoluminescence. The team is commonly using Time Resolved PhotoLuminescence and develop a new technique based on Modulated PhotoLuminescence. The perovskite team is on the other hand at the state of art of perovskite fabrication. In order to improve further the perovskite cells, characterization is needed to find the limiting physical factors.  A measurement campaign with the new coupled MPL/TRPL technics could allow to achieve part of this goal.

Main missions

The student will be in charge of a measurement campaign on perovskite solar cells with the modulated photoluminescence setup. The campaign will consist in:

  • Complete the existing bibliographical research
  • Choosing a protocol for measuring the cells (from absorber to complete cells)
  • Perform the measurements
  • Use a Matlab home code (already written but possibly modifiable) to make a first interpretation about the results

Expected profile


  • Semiconductor physics
  • English B1


  • Matlab
  • Optical instruments (Lasers)
  • Electronic instrumentation

Self-management skills

  • Self-organized
