Project R-13276

Towards the design and synthesis of quasi-2D Sn-containing perovskites with an enhanced stability for the development of efficient all-perovskite tandem 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, low cost and stable HOIP light absorbers and, to understand, predict and control their material properties. This will be possible thanks to the combination of the design and the synthesis of tailored large mono- and di-functional organic conjugated ligands and the related low bandgap (quasi-)2D HOIPs, fabrication of lab-scale single junction and all-perovskite tandem solar cells, and their detailed characterisation. The results obtained during my project will help cement the place of all-perovskite tandem solar cells in the solardriven water splitting field and pave the way towards affordable and efficient future routes for renewable chemical fuels. To this extent, I will exploit the wide possibilities of organic chemistry to fine tune chemical structures of large organic ligands and Sn-based HOIPs to the desired properties. The main goal is to gain a deep understanding of the factors/mechanisms inducing degradation and instability of the low bandgap Sn-based HOIPs and to use this acquired knowledge to enable the design of strategies to control and manipulate the material properties, e.g. stability and PCE when introduced as active layer in solar cells.
