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%.
Among the different materials available to fabricate the top cell of the tandem device, hybrid perovskites are particularly promising candidates. These materials have been recently applied to PV with a first proof of concept in 2009. Since then, a massive worldwide research effort has allowed to reach, in ten years only, efficiencies up to 25.7 % in single junction and up to 32.5% in tandem with silicon. These impressive performances have been obtained on small-scale surface cells and the tendency is now to develop up-scalable processes.
IPVF and CEA-INES are dedicating strong research efforts at high-level that have resulted in a consolidated expertise in the development of perovskite-based solar cell technologies. In this context, IPVF and CEA-INES are mutualizing research efforts in order to develop a two terminals Perovskite on Silicon tandem device based on the Heterojunction technology developed at CEA-INES. This collaboration particularly focuses on the development of a two-step deposition process combining the growth of an inorganic precursor by evaporation layer followed by its transformation into Perovskite compound by a wet method.
The selected candidate will benefit from a multidisciplinary environment, IPVF expertise and have access to IPVF unique capabilities.
