Missions

The main objective of the position is to perform macroscopic and nanoscale investigations on perovskite thin films and optoelectronic devices, in particular solar cells, in order to understand their metastability and the associated processes occurring at interfaces and in the bulk. The work will involve operando electrical and optical characterizations, spatially resolved analyses of performance and degradation mechanisms, and the development or adaptation of advanced experimental methodologies within the broader field of halide perovskite physics and chemistry.

Activités

Fabrication of functional perovskite solar cells and investigation of their electrical and optoelectronic properties at multiple length scales using advanced local microscopy and characterization techniques (such as scanning probe–based approaches); Study of charge transport, recombination, and metastability processes under different operating conditions (dark, illumination, electrical bias); Spatial analysis of performance inhomogeneities and degradation mechanisms using optical and electrical mapping techniques; Structural and functional characterization of interfaces and junctions, in particular through nanoscale analyses; Development, adaptation, and optimization of experimental methodologies for operando device studies.

Analysis, interpretation, and dissemination of scientific results.

Compétences

Required skills: PhD degree in physics, applied physics, materials science, physical chemistry, or chemistry; Strong motivation for experimental research; Ability to conduct independent research and to interact effectively within a multidisciplinary team; Good written and oral communication skills in English.
Desirable skills: Experience with thin-film photovoltaic materials (perovskites, colloidal quantum dots, etc.); Experience in optoelectronic characterization and/or device physics; Scientific interest and curiosity in materials chemistry.

Contexte de travail

The project will be carried out at LPEM, a CNRS research laboratory recognized for its activities at the interface of physics, materials science, and functional devices. The research will be conducted within the multidisciplinary MNC team, which develops advanced experimental approaches for the study of optoelectronic materials and devices. The postdoctoral researcher will work in a stimulating scientific environment that promotes interaction, collaboration, and innovation, and will benefit from the collective expertise, experimental facilities, and scientific network of the laboratory.
