Research Interests

My research focusses on the interaction between light and structured matter for the purpose of engineering novel optical concepts and nanophotonic materials for low-cost solar energy harvesting and lighting. I am currently particularly interested in perovskite thin-film solar cells and perovskite based multijuntion photovoltaics. My research involves the fabrication, characterization, simulation and understanding of the device physics of perovskite optoelectronic devices.

For a list of current research topics, please have a look at the webpage of my group.
