In my research group we are investigating the application of colloidal semiconductor nanostructures as light-harvesting elements in systems for light-driven water splitting. Towards this purpose we are working on molecular functionalization of the nanostructures with, e.g., reaction centers for hydrogen evolution, the controlled assembly of the particles and their integration in redox active polymers to design photoelectrodes. Applying time-resolved spectroscopic techniques we investigate the function determining interactions and light-driven processes in the designed materials.

Stephan Kupfer

Friedrich Schiller University, Jena


Stephan Kupfer received his PhD in 2013 from the Friedrich-Schiller-University Jena, Germany, where he is currently a group leader in the Physical Chemistry Department. His research is focused on the theoretical modeling of photo-induced processes, i.e., in the fields of solar energy conversion and plasmonic hybrid systems. For light-harvesting applications, either in the scope of (dye-sensitized) solar cells or light-driven water-splitting, detailed understanding of the fundamental photophysics and photochemistry is of uttermost importance. Therefore, he aims to elucidate as well as to tune excited state relaxation dynamics in (supra)molecular photocatalysts and light-harvesting antenna associated to electron and energy transfer processes, i.e., charge separation, charge recombination and photodegradation.

Dirk Ziegenbalg

Ulm University

The work of the Ziegenbalg research group focuses on fundamental investigations, optimization and design of photoreactors as well as photochemical processes. Optimization and design is based on fundamental knowledge of the photon fluxes in the reactors. For this, micro- and millistructured reactors, online-analytical methods, additive manufacturing and numerical simulations are applied as tools. Another topical focus lies on the application of light as tool for investigations in terms of reaction engineering.

Thomas Bocklitz

Leibniz Institute of Photonic Technology, Jena

Thomas Bocklitz' department investigates the entire data life cycle of photonic data, which extends from data generation to evaluation and archiving. The data life cycle is considered in a holistic approach and methods and algorithms for experiment planning, sample size planning, data pretreatment and data standardization are investigated. These methods are combined with chemometric methods, model transfer techniques and artificial intelligence methods in a data pipeline. This holistic approach makes it possible to use data from various photonic methods for analysis, diagnostics and therapy in various fields of application, e.g. medicine, the life and environmental sciences and pharmacy.

Martin Schulz

Friedrich Schiller University, Jena

Martin Schulz' research interests are in the field of artificial photosynthesis, where he develops and investigates photoredox-active transition metal complexes. His current research focus is on photoactive Cu(I) complexes for light-driven electron storage and transfer.

Andrea Pannwitz

Ulm University

The research group of Andrea Pannwitz is interested in photocatalytic conversions at membrane interfaces for light energy storage and solar fuels.


Stefanie Tschierlei

Technical University of Braunschweig

The research group of Stefanie Tschierlei is interested in the understanding and mechanistic studies of different photo- and electrocatalytic conversion processes. For this purpose, the group applies several steady-state and time-resolved spectroscopic techniques (from the fs to µs time regime) to investigate photoredox-active transition metal complexes in detail. Special focus is given to the light-driven activation of carbon dioxide and the reduction of protons to hydrogen.
