Non-covalent interaction engineering to tune the structural, optical, and electronic properties of layered hybrid perovskites

Abstract

Our society currently experiences an energy transition away from oil-, coal-, and natural gas-based energy sources towards more sustainable and environmentally less harmful energy sources, such as sunlight and wind power. Key to this energy transition are advanced materials that can efficiently harvest and consume energy from sustainable sources to generate electricity, light etc. Hybrid perovskites, which are the subject of this dissertation, are an example of such advanced materials to facilitate the energy transition. Over the past 15 years, hybrid perovskites have delivered high-performance solar cells, LEDs, lasers, transistors, and photodetectors.

By investigating layered hybrid perovskites with enhanced non-covalent interactions, we hope to shift the mindset of the perovskite researcher from inorganic chemistry, which has been dominating the perovskite field for the past decades, to organic chemistry, where especially the field of organic semiconductors holds the promise to produce excellent perovskite-based material systems and devices to power the global energy transition.
