Postdoc in Photovoltaic Cells and Semiconductor Physics in CEA INES – France

Summary

The French Alternative Energies and Atomic Energy Commission (CEA) invites applications for a 12‑month postdoctoral position at its Institut National de l'Energie Solaire (INES) in Le Bourget du Lac, France. The project, funded by the French National Research Agency (ANR), focuses on advanced characterization of degradation mechanisms in silicon‑perovskite tandem photovoltaic cells under illumination. The successful candidate will conduct pre‑ and post‑aging measurements (TRPL, EQE, XRD), collaborate with national partners for advanced analyses, perform semiconductor simulations, and develop Python‑based data processing tools. The role requires a PhD in semiconductor physics or related fields, strong Python programming skills, and proficiency in scientific English. The position offers a fully funded contract, access to cutting‑edge facilities, and an Alpine research environment.
