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

Over the last decade, perovskites have proven to offer powerful and yet intriguing materials for solar cell applications. Featuring excellent radiative efficiencies and remarkable versatility, perovskites have indeed shown an unpreceded increase in solar conversion efficiency, paving the way to disruptive devices. But a bottleneck remains the stability of these compounds, which suffer from rapid degradation in working conditions.

To investigate this issue, photoluminescence (PL) is a powerful technique granting access to a wide range of properties in photovoltaic materials and devices. It consists in analyzing the light radiated by a sample when submitted to a (laser) illumination. This light offers direct insights not only on the material’s composition, but also on the lifetime of photogenerated carriers or on their transport properties
The aim of this internship is to contribute to the implementation of an in-situ PL experiment, to study the degradation of a perovskite sample inside an ageing chamber with controlled environment (temperature, humidity…).

Main missions

The intern will be supervised by a post-doctoral researcher and will be in charge of:

– integrating a photoluminescence setup into the climate chamber,

– making a user-friendly Labview interface for automating the measurements and add necessary functionalities for long period of time acquisitions,

– write an operating instructions manual,

– planning and conducting photoluminescence measurement campaigns,

– collect and summarize the experimental data,

– participate in data analysis.

An excellent chance to learn project development!
