Project R-15243

Impact of Resonance Energy Alignment and Interlayer Distance tuning on Charge Carrier Mobility in quasi 2D Hybrid Perovskites as Active Materials in Perovskite Solar Cells. (Research)

The aim of my Ph.D. project is to contribute to the clean energy transition challenge focusing on the research of innovative, efficient, and stable Hybrid Organic-Inorganic Perovskite (HOIP) light absorbers and, to understand, predict and control their material properties. This will be possible thanks to the design and synthesis of tailored large mono- and di-functional organic ligands and the related (quasi-)2D HOIPs, fabrication of lab-scale single junction hybrid perovskite solar cells, and their detailed characterization. The main focus of my project is to define and synthesize the organic systems with the aim of achieving strongly improved vertical charge transport to rival charge transport in their less stable 3D counterparts. In this way, potentially, the high stability of quasi-2D HOIPs can be merged with competitive solar cell performances of 3D perovskite solar cells. I believe that gaining a deep understanding of the structure-property relationships of such advanced 2D HOIPs will also allow for the introduction of this material class in other electronic devices besides solar cells. This will contribute strongly to the development of hybrid perovskite-based electronics.
