Our group develops novel semiconducting materials and studies their interactions in thin film architectures to address global energy challenges.
Materials Development
Synthesis and processing
THIN FILM VACUUM DEPOSITION
Organic and perovskite semiconductors are deposited into functional thin-films through a variety of vacuum and solvent based deposition processes. The successful implantation of vacuum techniques in modern well-established technologies can be a reference for perovskite photovoltaics.
SOLID STATE CHEMISTRY
Mechanochemical synthesis is an ideal platform for the development of novel multinary metal halide semiconductors and phosphors.
COLLOIDAL SYNTHESIS
Nanocrystals allow to enhance the optoelectronic properties of metal halide perovskites as compared to bulk materials.
Device integration
Thin-film optoelectronics
PHOTOVOLTAICS
Perovskite solar cells have revolutionized the field of thin-film photovoltaics in less than one decade. We focus on industry-relevant processes to prepare single junction and tandem devices.
LIGHT-EMITTING DIODES
Lighting represents one of the main sources of electricity consumption. Our group develops novel concepts for efficient electroluminescent displays and light applications.
PHOTODETECTORS
Optical sensing encompasses a variety of applications in domestic, industrial and clinical environments. Materials and devices can be tuned for selective and fast photon detection.
Physical characterization
Working mechanisms
OPTOELECTRICAL ANALYSIS
Limiting factors underlying the processes of charge injection, transport and recombination are identified through steady-state and time-resolved techniques.
STRUCTURE-PROPERTY STUDIES
We study the influence of the material composition and arrangement, from the atomic (crystal structure) to the nano- and microscale (grain boundaries, morphology and film architecture), on the macroscopic electronic and optical properties.
