Camille is a Doctoral researcher investigating the photophysics of perovskite materials for novel solar cell and LEDs. Originally a theoretical physicist with a BSc in Fundamental Physics from the University Paris VI which included an exchange year at the National University Singapore, followed by a Masters in Condensed Matter from Paris VI and the University of Uppsala, Sweden.
The project aims to “Explore non-radiative loss mechanisms and recombination pathways in metal-halide perovskite through 3D photoluminescence tomography.” The Strank’s group recently found that light and atmospheric treatments on polycrystalline perovskite thin films resulted in large enhancements in the luminescence of the dark grains, with macroscopic optoelectronic properties approaching those of the best crystalline semiconductors reported to date. The visit of Camille for three months would enable samples produced in Cambridge to be studied with subsurface two-photon microscopy, a technique pioneered by Edward Barnard to study photovoltaic materials. The results may lead to a detailed understanding of the charge dynamics that are crucial for further improvements in device performance of perovskite-based solar cells and LEDs.
