IPVF Internship – Tandem solar cells silicon/wide gap CIGS


Function: Master student

Contract Type: Internship

Starting Date: March 2022

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

Duration: 6 months

Education: Master 2




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.
• 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).





The internship will be involved in a research project focusing on tandem Silicon / Cu(In,Ga)(S, Se)2 (CIGS) solar cells. The two solar cells are superimposed, each cell absorbing a specific part of the solar spectrum to maximize the overall efficiency.
