Electrocatalysis

Prof. Dr. Karl MayrhoferThe research interests of the research department “Electrocatalysis” are on electrochemical reactions that occur at solid-liquid interfaces and are relevant to electrochemical energy conversion (fuel cells, water or CO₂ electrolyzers etc). Reactions of interest are: oxygen evolution, oxygen reduction, carbon dioxide reduction and others. Our focus is placed on finding active, selective and stable electrode materials for such reactions and thereafter the integration to real systems.

Dynamics of Complex Fluids and Interfaces

Prof. Dr. Jens HartingThe research focus of this HI ERN research department is the development of simulation and modeling techniques for printing and coating processes for thin film production. The results of this work are supposed to enable an optimized production of solar cells and electrocatalytic active films. The theoretical work of this section perfectly connects the HI ERN research areas “printable photovoltaics” and “hydrogen as secondary energy source”.

Electrocatalytic Interface Engineering

Prof. Simon ThieleThe Electrocatalytic Interface Engineering (German: Elektrokatalytische Grenzflächenverfahrstechnik, EGV) research department concentrates on technical interfaces of electrocatalytic devices. Examples of such technical interfaces are the catalyst layers, membranes or transport layers as well as their interfaces in e.g. fuel cells or electrolysers. The central research question for the field of the research department is: How to get the best possible structure for the functionality of a given interfacial layer or layer system?

High Throughput Methods in Photovoltaics

Prof. Christoph BrabecDr. Jens HauchThe research department „High Throughput Methods in Photovoltaics“ aims to develop materials, processes and technologies fostering a sustainable and significant cost degression of the photovoltaic technology, from small non-gird connected energy harvesting to large scale energy production and from the Watt scale to the Terawatt scale. The research combines achievements from automated materials research, digitization, simulation and big-data methods with the specialized knowledge of Photovoltaic technology.

X-ray spectroscopy at interfaces of thin films (HZB)

Prof. Dr.-Ing. Marcus Bär

The research department "X-ray spectroscopy at interfaces of thin films" is renowned for combining different lab- and synchrotron-based photon-in – electron-out and photon-in – photon-out spectroscopic methods to interrogate the chemical and electronic structure of energy conversion materials and thin-film layer stacks, with a particular focus on photovoltaics. The core expertise of the group is to non-destructively reveal composition and electronic structure profiles by deliberately employing different spectroscopies excited with soft and/or hard x-rays.
