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.





Renewable energies constitute a growing part of the energy mix worldwide. In the past few years, photovoltaics have seen an impressive increase in installed capacity, strongly supported by R&D centers.

The efficiency of the silicon technology – that represents 90 % of the market – comes closer and closer to its theoretical limit (c.a. 29%). In order to further improve the photovoltaic (PV) conversion efficiency significantly, technological breakthroughs are needed. A promising pathway towards higher efficiency 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 25.5% in single junction and up to 29.5% in tandem with silicon.

In this context, IPVF has fabricated >20% perovskite solar cell with a gap >1.6 eV and developed perovskite modules with efficiency up to 18%. These impressive performances have been obtained on small-scale surface cells and the tendency is now to develop up-scalable processes.

IPVF is now looking for a R&D engineer to join its talented team (ca. 20 people) to work on the development and optimization of materials, cells and processes for perovskite and tandem solar cells.

The candidate will benefit from a multidisciplinary environment, IPVF expertise and have access to IPVF unique capabilities.

Main Missions

As part of our growth, we are looking to strengthen our Programs Direction with the recruitment of an R&D Engineer to join the Program “Perovskite/Silicon Tandem Module” and its talented team (around 20 people) to work on the development and optimization of large-scale processes for perovskite and tandem solar cells.

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 Perovskite Team, your activity will revolve around high-performance photovoltaic applications, and will notably include in-depth research and development work, consisting of:

• Conduct R&D studies for the development of laser-manufactured perovskite-based solar devices. A particular focus on the optimization of electrical connection at the micro scale will be carry on.
• Optimize and implement innovative encapsulation process (technology watch, process optimization for different architectures, conduct stability and reliability tests following industrial protocols).
• Produce small devices and larger mini-modules with a quality control methodology to supply the team, other collaborating projects, and in the framework of external requests.
• Prepare working substrates (cleaning, coordination with ALD team…) to support the activities of the group researchers.
• Participate in the development of PV indoor applications (IoT and autonomous device applications, Prototypes, …)
• Report results to engineers and researchers.
• Coordinate her/his work with colleagues to ensure the smoothest productions of samples.
• Propose and implement technical improvements.
• Technical support for equipment maintenance and ordering of consumables.
• Apply the relevant health and safety rules.
• Adapt to technological developments.





– PhD/M.S. in materials science, micro-electronics or chemistry.

– General knowledge of solar cells and thin film deposition and structuration (wet, vacuum, laser, …).

– Knowledge of perovskite solar cells is an asset.




– Hands-on experience in equipment and process for materials science.

– Prototyping and “fablab” mindset.

– Demonstrated experience in photovoltaics device fabrication, characterization and/or electronic skills is a plus.



Self-management skills :

– Desire to work in the labs.
– Curious, enterprising and creative.
– Autonomous.
– Excellent communication (written and oral) skills.
– Collaboration with cross-functional and diverse teams.
