Become an actor of the Energy Transition by joining a team driven by innovation and impact to address today’s most decisive challenges.

IPVF is one of Europe’s leading research, innovation and education organizations whose mission is to accelerate the energy transition through science and technology. Supported by the French State, IPVF is labelled Institute for Energy Transition (ITE).

Bringing together recognized industrial leaders (TotalEnergies, EDF, Air Liquide, Horiba and Riber) and world-renowned academic research teams (CNRS, Ecole Polytechnique), IPVF’ multidisciplinary and international teams conduct research dedicated to clean energy technologies (photovoltaics, green hydrogen, etc.). IPVF has built an ambitious scientific and technological research program, divided into 6 programs and 24 sub-projects, to achieve this objective.
These programs are based on a high-level experimental platform of 8,000 m², located in Paris-Saclay, and comprising more than 100 cutting-edge equipment worth €30M.





IPVF optical characterisation lab is at the forefront of the development of advanced characterisation methods for solar cells with a solid expertise on hyperspectral luminescence and Time-Resolved FLuorescence Imaging (TR-FLIM) as well as in the advanced characterisation of emerging materials and innovative cells architectures.
In the last decade, mixed halide perovskites have attracted a strong interest in the photovoltaic community as a result of their high-power conversion efficiency and the solid opportunity to realize low-cost and industry-scalable technology. However, important progress still needs to be done regarding upscaling and long-term stability of perovskite devices. This post-doc position is opened to support IPVF in solving these issues by optically and electrically characterizing the devices produced by and in collaboration with the synthesis team. The devices will be individual cells/modules and tandem Pvk/Si of small (0.1 cm²) up to large size (6” square), in initial state and/or after/during ageing under various environmental stresses.



As part of our growth, we are looking to strengthen our Programs Direction with the recruitment of a Postdoc to join the Program “Reliability, characterization and modeling” and its talented luminescence team (around 10 people) to work on the multidimensional analysis of perovskite solar cells and tandem devices by luminescence imaging and electrical measurements.


The candidate will report directly to the Programs Deputy Director of IPVF and will benefit from a multidisciplinary environment, IPVF expertise and will have access to IPVF’s unique capabilities.


Within the Luminescence Team, the postdoc will conduct multidimensional (time, spectrum, temperature, voltage…) analysis of perovskite solar cells and tandem devices by luminescence imaging and electrical measurements coupled with appropriate data treatment. Moreover, he/she will collaborate with teams dedicated to compositional/morphological characterization to link optical/electrical properties and material structure. He/she will conduct simulation studies when simple or in collaboration with theory/simulation teams. The publication of results will be particularly tracked in this framework as well as communication in conferences.
