I intend to broaden the international perception of HOIPs beyond photovoltaic materials, explore their fundamental liquid and glass forming behaviour, and create a family of related amorphous materials for power generation from waste heat, i.e. thermoelectrics. In my previous position at the University of Cambridge, I recently discovered this liquid- and glass- forming ability of crystalline hybrid perovskite frameworks. These are important given (i) they are only the second known family of hybrid glasses, i.e. those formed from connected inorganic and organic components, and (ii) they were found to exhibit lower thermal conductivities than other glasses from traditional inorganic, and organic families. This behaviour is extremely promising for applications as thermoelectrics, and the further improvement of behaviour, alongside exploration of the optical and mechanical properties of this new family of glasses, forms the bulk of the research in this present Humboldt position.
