Spectroscopy at the nanoscale in perovskite nanocrystals


In the field of organic photovoltaics there is a rising star in the family of perovskites called methylammonium lead iodide (MAPbI3).  This semiconductor material can readily be used for solar cell applications as well as light emitting technology due to its exceptional electronic and optical properties. Absorption is very broad and charge carrieres are extremely long lived, which creates ideal conditions for solar cells. At the same time the material has a direct bandgap, which makes it an efficient light emitter.

In the Single Molecule Spectroscopy group we aim to study these properties on an individual crystal scale since ensemble measurements often obscure them. Our goal with this project is to further the understanding of the fundamental processes in these materials under operational conditions.
