The project objective involves studying the degradation mechanisms under illumination of silicon-perovskite tandem solar cells, both at the material and interface levels. This study includes a set of characterizations to be carried out before and after aging, notably time-resolved photoluminescence, external quantum efficiency, or X-ray diffraction. Additional measurements will also be carried out by our project partners, jointly selecting the appropriate analyses to refine the diagnosis, for example using XPS, HAXPES, ToF-SIMS, TLM, KPFM or GDOES. Based on an existing model, simulation work will be carried out to study the dynamic phenomena related to the lifespan of these solar cells.

The work includes physical measurements, semiconductor simulation, algorithmics, imaging, and Python programming. It is based on a bibliographic study and on the experimental handling of characterization tools.

The job takes place at the Institut National de l’Energie Solaire (INES), in Le Bourget du Lac (73), near Chambéry. The work will be carried out as part of a project funded in particular by the French National Research Agency (ANR) with several partners at the national level.
