IPVF

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.

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 5 programs and 19 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.

 

CONTEXT

IPVF has launched the Program PEARL to explore breakthrough approaches for future photovoltaic innovations. Atomic Layer Deposition (ALD) has been selected as the method of choice to address PV challenges, by coordinated efforts in molecular chemistry, surface chemistry, material science, modeling and instrumentation.
We have recently developed an innovative in situ diagnostic tool that combines spectroscopic ellipsometry (SE) and luminescence-based techniques (Photoluminescence PL and Time Resolved PL TRPL), to simultaneously probe, at nanometric level, both material properties and function during its growth. This tool is intended to assist the development of new functional materials, gain understanding on material growth/property and accelerate their efficient integration in solar cells.
The doctoral researcher will benefit from IPVF expertise and unique capabilities in both ALD material development and optical structural characterization techniques.

 

MAIN MISSIONS

The candidate will directly report to the Programs Deputy Director of IPVF.

She/he will integrate a dynamic and talented team driven by innovation and results. Using the unique home-built diagnostic system, her/his main missions will consist in consolidating the proof-of-concept PL/SE system to develop efficient novel functional materials integrated in solar cell, i.e.:


– Set up and perform ALD experimental design, i.e. determine ALD parameters that allow the fabrication of highly controlled functional thin films,
– Finely characterize the growth mechanisms with in-situ SE,
– Characterize the materials’ structural, morphological, electrical, and optical properties with in/ex-situ techniques,
– Optimize the materials properties (e.g. with thermal post-treatments),
– Integrate the layer in perovskite-based solar cell.

 

The missions being highly interdisciplinary, the candidate will interact and collaborate with IPVF’s teams as ALD is part of the cells’ production steps but also with different lab partners.
