Offer Description
As part of the Minotaure project, which addresses the issues of reliability and durability in new photovoltaic cell technologies, studying the mechanisms of solar cell degradation is a major challenge. In order to analyze and understand these mechanisms, and subsequently circumvent or eliminate them, a group of partners with complementary expertise in various fields of characterization and modeling have joined forces to study aging mechanisms using operando, in situ, and ex situ characterization approaches.
This 12-month postdoctoral contract aims to identify and understand the chemical or electrochemical changes induced by the main stress factors related to aging, namely temperature, light, electrical polarization, and various combinations of these factors, both in the absorbing layers and at the interfaces of solar cells based on perovskites or chalcopyrite Cu(In,Ga)(S,Se)2, technologies selected for the production of low-cost tandem cells.
The effects of various in situ aging factors and the combination of these factors will be studied by combining two complementary surface analysis techniques:
ToF-SIMS and XPS, which will provide access to high-resolution depth profiles, 2D and 3D images, the distribution of elemental and molecular species, and changes in chemical and electronic properties. The XPS analyses will be carried out at the Lavoisier Institute in Versailles and the Jean Rouxel Institute of Materials in Nantes, while the ToF-SIMS analyses will be carried out at the Paris Institute of Chemistry Research.
• Aging of solar absorber layers with in situ monitoring of their properties using XPS and ToF-SIMS
• Chemical correlation of results obtained using XPS and ToF-SIMS
• Development of an in situ electrical bias process for ToF-SIMS measurements
The successful candidate will join the Electrochemistry and Physical Chemistry at Interfaces (EPI) group at the Lavoisier Institute in Versailles (UMR 8180 CNRS-UVSQ Paris Saclay). They will carry out their ToF-SIMS experimental work at the Paris Institute of Chemistry Research (Paris 5th arrondissement). Finally, assignments will be planned at the Nantes-Jean Rouxel Materials Institute.
