IPVF – Photovoltaic Institute of Île-de-France

The Photovoltaic Institute of Île-de-France, institute for energy transition, is a scientific and technical center dedicated to the research and development of solar technologies. On its site located in Paris-Saclay, it brings together its own staff, employees of its partners and those of external companies. The IPVF aims to ambition to become one of the main global centers for research, innovation and training in the field of energy transition.

The IPVF aims to primary objective of improving the performance and competitiveness of photovoltaic cells and developing disruptive technologies relying on four levers:

• An ambitious research program;
• The reception, on its Paris-Saclay site, of more than 200 researchers and their laboratories;
• A cutting-edge technological platform (8 m²) open to players in the photovoltaic sector, and bringing together more than 000 cutting‑edge equipment located in clean rooms.
• A training program mainly based on a master's degree, supervision of doctoral students, and continuing education.

JOB CONTEXT

The responsibilities of this position are aligned with the IPVF's objective of being a major player in advanced characterization, and more specifically in key expertise techniques such as XPS (X‑ray photoelectron spectroscopy) and photoluminescence (PL). Expertise in these techniques contributes to the institute's visibility and, internally, supports a thorough understanding of the processes.

The candidate will report directly to the head of the characterization and modeling team and will contribute to the ICARE program. They will join a multidisciplinary and dynamic team.

What we offer: As part of a growing international technology organization that places innovation, excellence, and agility at the heart of its values, we offer a work environment that values team spirit and promotes training. The IPVF will allow you to express your potential and demonstrate your skills in characterization of innovative materials.

MAIN MISSIONS

Advanced Characterizations

• Develop measurement strategies (X‑ray photoelectron spectrometry (XPS), X‑ray scanning electron microscopy / energy‑dispersive X‑ray analysis (SEM/EDX), glow‑discharge optical emission spectroscopy (GD‑OES), photoluminescence (PL), electroluminescence (EL), X‑ray diffraction (XRD), X‑ray fluorescence (XRF), Raman spectroscopy, UV‑visible spectroscopy (UV‑VIS), current‑voltage (IV) characterizations, external quantum efficiency (EQE), etc.) for the characterization of samples to guide the technological choices of the IPVF on its strategy for making the manufacturing processes of perovskite solar cells more reliable.
• Define and undertake experimental work aimed at understanding the interactions between measurement techniques and the behavior of materials.
• Ensure the maintenance and continuous improvement of tests by monitoring measuring devices and systems, including maintaining equipment calibration.

Developments based on XPS/GD‑OES coupled with Photoluminescence (PL)

The correlation between XPS/GD‑OES analysis and PL imaging is a central research focus for IPVF, and promising results have already been obtained, suggesting that IPVF's technical advances will have significant implications.

Developing a multi‑scale and multi‑technique approach to identify the best passivation agents (quasi‑2D perovskites, SAMs) and to study the different degradation processes occurring at the absorber/transport layer interfaces will be the direct application supporting the IPVF processes developed. This will be achieved using chemical characterization techniques, namely XPS and EDX, to monitor the evolution of chemical species on the surface and within the volume of the thin films.

• Correlate chemical characterizations with continuous and time‑resolved PL imaging measurements to identify major non‑radiative losses and determine surface and volume recombination rates.
• Analyze and develop proposals for improving the design and optimization of efficient and reliable perovskite devices.

REQUIRED PROFILE

• Experience working in a laboratory and/or cleanroom in the characterization of solar cells and modules
• Knowledge of XPS (X‑ray photoelectron spectroscopy) (required)
• Knowledge of GD‑OES (Glow‑discharge optical emission spectroscopy) (important)
• Knowledge of advanced characterization techniques (photoluminescence (PL), electroluminescence (EL), X‑ray diffraction (XRD), X‑ray fluorescence (XRF), Raman spectroscopy, UV‑visible spectroscopy (UV‑VIS), current‑voltage (IV) characterizations, external quantum efficiency (EQE), etc.) is a plus.
• Ability to work in a team within an interdisciplinary environment
• Ability to work within experimental constraints
• Results orientation, tenacity to accurately assess, solve, implement and communicate the results of complex challenges.
