This grant covers three themes defining our research goals and which lie within the University of Basel's focus area of 'Energy and Sustainability'. The goals of each sub-project are distinct, but the underlying chemistry and methodology are not mutually exclusive.
The first subproject strives to maintain our international leading position in the area of dye-sensitized solar cells (DSCs). We are at the cutting edge of developing DSCs with dyes based on Earth abundant metals and we will extend this to DSCs in which both dyes and electrolytes comprise sustainable components. A major reason for our success in this field is the application of hierarchical assemblies. Our methodology is termed 'surfaces-as-ligands, surfaces-as-complexes' (SALSAC) and extends 'simple' self-assembly and self-organization at surfaces to stepwise and hierarchical building up of new architectures.
The second sub-project B develops multifunctional surfaces.
The third project concerns light-emissive materials for application in light-emitting electrochemical cells (LECs) and we will focus on the use of Earth-abundant copper. This sub-project will advance our knowledge of molecular design for copper-based emitters and will diversify the ligand types to enhance emission behaviour.
