Context & Environment

To meet its ambitious objectives of energy transition towards electricity and renewable energies, the OneTech entity of TotalEnergies gather all the technical departments providing technical support to operations and R&D (Exploration & Production, Refining & Chemistry, Marketing & Services and Gas, Renewable Energy & Electricity). With a workforce of 3,400 people, OneTech is divided into three divisions: an industrial division supporting the company's development in gas, renewable energies, electricity and the reduction of carbon emissions; a research and development center bringing together all of TotalEnergies' research activities to anticipate the transformation of the company, giving priority to the low-carbon mix; and a support center (HR and finance).

By integrating all of the company's technical and R&D expertise within a single entity, OneTech becomes one of the pillars of the transformation of TotalEnergies into a multi-energy company.

Activities

New photovoltaic technologies are emerging in the market, significantly different from the systems currently in use. As we prepare for this transition, it is crucial to understand, measure, and test these innovations correctly. This knowledge will enable us to provide valuable support to our Business Units navigating these advancements and ensure the efficient and sustainable development of photovoltaic (PV) projects.

OneTech is seeking a Postdoctoral R&D researcher in private law: Reliability and Performance Engineer, New Photovoltaic Technologies based in Paris-Saclay, whose primary role will be to develop protocols and deepen our understanding of these new technologies, particularly perovskite and tandem configurations.

Fixed-term contract with a minimum duration of one year and a maximum of three years, renewable once for a total duration of up to four years.

As a Postdoctoral R&D researcher - Reliability and Performance Engineer, New Photovoltaic Technologies , your main activities will be as follows:

• Monitor and analyze the performance and reliability of emerging technologies cells and modules, with a focus on outdoor perovskite installations. It can involve private R&D installations, industrial pilots, or test-site in collaborations with other research institutes such as IPVF (Institut Photovoltaïque d'Ile de France).
• Adapt the existing outdoor testing installation and protocols if necessary, to accommodate perovskite and/or tandem PV modules procured externally, for performance and reliability studies.
• Define and conduct accelerated aging tests and reliability studies to evaluate long-term stability and durability of the devices
• Follow the developments of the PV community on perovskite and tandem qualification standards.
• Advise on indoor testing equipments requirements to anticipate needs of perovskite and tandem PV modules.
• Define and implement process documentation such as Standard Operating Procedures.
• Contribute in the European Project "LAPERITIVO" involving several partners, by running indoor accelerated test on the devices of the project, and report results.
• Conduct in-depth loss mechanisms analysis and communicate these insights internally and to IPVF Common Program teams to further improve the performance of the developped perovskite single-junction, multi-junction solar cell, mini-modules and modules (substrates provided by different partners).
• Ensure the compliance with the HSE regulations of the lab and the Group.

Candidate Profile

• You are a doctor with a background in materials or renewable energy.
• You have a previous experience or a PhD on a solar PV-related topic, ideally thin-film technology such as perovskite
• You possess skills in Python programming and the analysis of large datasets.
• You are proficient in several languages, with English being required and French desirable.
• You have excellent written and verbal communication skills, and you are capable of interacting with diverse and multicultural teams.
• You demonstrate proactivity and are ready to take on responsibilities.
• Your scientific curiosity, sense of innovation, and rigor in project management are assets.
• Additionally, you are able to conduct multiple studies simultaneously within multidisciplinary teams.
