Research Interests

Quantum Sensors and Microwave Emitters

In recent years, wide-bandgap semiconductors, such as silicon carbide (SiC) attracted a lot of interest as a technologically perspective platform for quantum spintronics with the ability for single spin engineering and control. Our group is interested in atomic scale color centers in SiC, particularly silicon vacancies, which combine resonant optical addressability using near-infrared light and long spin coherence times.

Spins in Organic Semiconductors

Organic semiconductors are a promising class of materials for the next generation of light emitting diodes (OLED) and solar cells (OPV). Several phenomena in these semiconductors are related to the spin properties of triplet excitons and charge transfer states that are optically or electrically generated in device active layers and can influence the charge carrier generation and radiative recombination quantum efficiency. In other words, spin is a crucial parameter controlling the physical limits of device quantum efficiency.

Photovoltaic Materials and Devices

Our research activities are focused on the physics of organic and, more recently, hybrid perovskite photovoltaics. Perovskite photovoltaics is a relatively new type of thin-film PV technology, which experienced a tremendous increase in power conversion efficiency from 3.8 % to above 22 % within the last 10 years.
