EDF Internship – Stability and reliability measurements on perovskite-based cells


Function: Master student

Contract Type: EDF internship

Starting Date: March 2022

Working Place: Palaiseau, France (Paris-Saclay technology cluster)

Duration: 6 months

Education: Master 2




To bridge the gap between education and the world of work, EDF welcomes more than 1 500 interns every year studying for qualifications  that range from a post high school certificates to master’s degrees. In the context of its research activities in photovoltaic (PV), the R&D department of EDF contributes to IPVF.


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.
• 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…).
• High-standard Education program (M.S. and PhD students).




Perovskites solar cells is the rising star of photovoltaics with great promises ahead, especially in their association with silicon solar cells to create tandem PV modules exceeding standard PV module expected efficiency limit (~25%).

Nonetheless, perovskites solar cells and modules do not meet yet the requirements of stability and reliability, especially when compared and/or associated with silicon solar cells. Research institutes are working hard on developing stability and reliability protocols enabling the assessment of perovskite-based devices long term performance. Indoor and outdoor performance analysis of perovskite-based devices developed at IPVF is a crucial step for their future deployment by industrials.




The main objective of the internship will be to perform different indoor measurements on perovskite-based cells. A comparison with outdoor measurements will be performed in parallel. The intern will perform aging measurements with different temperature and humidity conditions.
