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.
Renewable energies constitute a growing part of the energy mix worldwide. To further improve the photovoltaic (PV) conversion efficiency, technological breakthroughs are needed. A promising pathway towards higher efficiencies is to combine the crystalline silicon solar cells with a material that converts more efficiently the most energetic part of the solar spectrum (i.e. UV-visible region). This technology, called tandem solar cell, consists in stacking two difference systems to push the theoretical efficiency limit from 29% up to 42%.
IPVF has launched the ambitious Program “IMPACTS” for the development of perovskite/silicon (PVK/c-Si) tandem modules.
IPVF is looking for a Research Engineer/Postdoctoral researcher to join its talented team (ca. 20 people) to work on the development of PECVD processes to adapt bottom c-Si solar cells to perovskite top cells in a monolithic 2T approach.
The selected candidate will benefit from a multidisciplinary environment, IPVF expertise and have access to IPVF unique capabilities.
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.
The main missions will be divided in two tasks.
The first half of the mission will be dedicated to silicon deposition by PECVD as tunnel junctions and will include:
– Deposition of tunnel junctions (nc:Si:H, polySi, a:Si:H, µc-SiOx…) by PECVD and/or ALD.
– Characterize the developed junctions (electrically, chemically).
– Work in close collaboration with the other IMPACTS’ Work Packages for the integration of the developed tunnel junction in 2T tandem solar cells.
– Implement tunnel junction processes for various c-Si bottom cell technologies (HJT, PERC, IBC…).
– Build on the expertise and developments already achieved and transfer the recipes to the industrial PECVD at IPVF.
– Be in charge of the PECVD equipment based at IPVF.
The second part of the mission (reasonably starting after ca. 18 months) will consist in:
– Optimize the perovskite top-cell fabrication by evaporation and wet processes.
– Integrate the developed perovskite into a 2T tandem structure with the optimized tunnel junctions and different c-Si bottom cell technologies (planar and textured).
– Characterize the opto-electrical properties of the materials and devices.
Knowledge:
– M.S./PhD degree in Materials Science, electrical engineering or related.
– Knowledge in physics of semiconductors.
Know-how :
– Extensive experience in vacuum-based thin film deposition.
– Hands-on experience with PECVD and ALD.
– Proficiency in photovoltaics is desirable.
– Strong expertise in Silicon thin film deposition for PV is an asset.
– Knowledge in perovskite is an advantage.
Self-management skills :
– Team spirit,
– Self-initiative and creativity,
– Autonomous and rigorous,
– Results-oriented.
