Results in brief
Stable Halide Perovskite Nanocrystals for Efficient Optoelectronic Devices
The increasing demand for clean and renewable energy requires the development of improved strategies and materials to obtain energy from renewable sources. Improved efficiencies for solar cells, photocatalytic CO2 reduction and water splitting are highly investigated, but also more efficient ways to use electrical energy for lighting must be developed. These challenges are also recognized by the European Energy Efficiency Plan. Perovskites have shown impressively high efficiencies for solar cells and light emitting diodes but stability issues are still a big problem, which currently hinders the wider commercialization and the fabrication of perovskite based devices. The StabPerov project succeeded in developing strategies for the synthesis of highly stable perovskites by using amphiphilic molecules as coating materials and contributed to the structural and optical characterization of these nanocrystals.

Project objective
Perovskites have shown impressively outstanding performance in solar cells and light emitting diodes (LEDs) but are still limited by the non-negligible stability issues. With high efficiency achieved, now it is time to fill the research gap for pursuing stable perovskites. My priority goal for the StabPerov project is to obtain highly stable perovskite nanocrystals by using amphiphilic molecules such as liposomes. Upon successful realized, more stable optoelectrical devices can be explored targeting one of the most serious concern for commercialization of perovskite based applications. At the beginning of my project, I will optimize the synthesis of perovskites nanocrystals. For coating perovskites, amphiphilic molecules are used as coating materials. The amphiphilic molecules may also function as ligands. Different types of amphiphilic molecules will be introduced. Detailed and comprehensive characterizations of (HR)TEM, XRD and optical spectroscopy of materials will be carried out before and after degradation. The stability improvement of perovskite nanocrystals is now urgent, whilst getting the insight of how perovskites are decomposed is also necessary with regard to optimize synthesis and to evaluate protected nanocrystals. At the next stage, the as-prepared high quality stable perovskite nanocrystals will serve as emitters and catalysts for the demonstration of applications. My results are of great feasibility and practical significance, which pave the way towards the applications of stable high performance perovskite based devices. Combining my background with the training of optical spectroscopy offered by the host as well as being an independent investigator of this project, the Marie Curie fellowship will not only provide an excellent chance for me to become a research group leader in my future career, but also offer a markedly benefit to the development of sustainable energy for society by more efficient and more stable solar cells and LEDs.
