The preparation of wide bandgap (WBG)-MPH layers for tandem top cells requires ad hoc halide mixtures and generate additional stability issues due to the halide segregation that can occur upon aging. These perovskites classically experience instability and phase segregation phenomena that must be suppressed. The preparation of stable and high- quality WBG-MHP films needs a fine control if the crystallization process. The aim of the thesis is to develop strategies to increase the stability of WBG-MHP films. The formation of the targeted phase will be reached by finely controlling the composition of the precursor solution. The use of alkylammonium additives combined with ammonium compounds at the origin of 2D phases formation will be investigated. The student will examine in-depth the film structure and composition changes upon the various preparation steps notably to understand the ammonium group deprotonation, the halide ion exchanges and the elimination by volatilization of certain species. The remaining of the others will bring the final properties to the absorber films, especially the bandgap, the crystallinity, the microstructure and the stability properties. The global thermally induced dimensional increase of the MHP will allow to boost the properties. The efficiency and stability of the inverted solar cells prepared with these compounds will be studied. Required background of the student: Material science; Chemistry; Physics of semiconductors; Photovoltaics; Material characterization techniques (SEM, XRD, UV-Vis absorption).

Nanomedicine is an effective approach to meet these requirements because the coupling and encapsulation of antitumor molecules with nanovectors will allow reducing their toxicity while improving their circulation and in vivo targeting. The association with imaging probes will eventually give rise to theranostic agents. The PhD proposal aims to explore the interest of carbon dots for theranostic applications. The lab has already developed some nanostructurations and aims at characterizing these nano-theranostic agents in terms of interactome (« protein corona » or « antifouling » capacity in physiological media) and the evaluation of their biological and theranostic properties, for an efficient pre-screening for biomedical applications.
