Patric Seefeldt

Dr.-Ing. Patrick Seefeldt, Deutsches Zentrum für Luft- und Raumfahrt e.V. (DLR), Institut für Raumfahrtsysteme | Mechanik- und Thermalsysteme

Development of new Solar Array Concepts for Space Applications

Solar arrays are the main power source in space. Conventionally they are composed of stiff backing structures and brittle PV cells. While the power demands of space missions are increasing, e.g. for electric propulsion, the increase of…

Dr. Adrian P. Tighe, ESA/ESTEC

Radiation testing of materials and prospective technologies for future space missions

In this talk I will give an overview of some of the challenges related to the radiation testing of materials for space applications, describing some of the test facilities and techniques, showing results of…

Hans Rabus

Dr. Hans Rabus, Physik. Techn. Bundesanstalt

High-Z nanoparticles for enhanced energy deposition in tumours during radiotherapy

Radiotherapy is a trade-off between tumour control and unwanted side effects in healthy tissue. Both radiation effects depend on the absorbed dose, i.e. energy imparted per mass. Due to proliferation, cancer cells…

Michael D. McGehee

Prof. Michael D. McGehee, Univ. Boulder, Colorado

Triple Halide Perovskite Absorbers for >27% Perovskite/Silicon Tandem Solar Cells with Excellent Stability

Wide bandgap metal halide perovskites are promising candidates to pair with low bandgap silicon, copper indium gallium diselenide, or perovskite photovoltaics for highly efficient…

Speakers on 30 September 2021

Thomas Frauenheim

Prof. Dr. Thomas Frauenheim, BCCMS, Uni Bremen

Ultrafast energy transfer through intermolecular Conical Intersections

Conical intersections (CoIns) of multidimensional potential energy surfaces are ubiquitous in nature and control pathways and yields of many photo-initiated intramolecular processes. Such topologies can be potentially involved…

Caterina Cocchi

Prof. Dr. Caterina Cocchi, Carl von Ossietzky Universität Oldenburg; Humboldt-Universität zu Berlin

Donor/acceptor interfaces in organic and hybrid materials for photovoltaics: Insight from first-principles calculations

Donor/acceptor interfaces are ubiquitous building blocks of organic and hybrid materials for optoelectronic and photovoltaic applications. In-depth understanding of their…

Kai Nordlund

Prof. Dr. Kai Nordlund, Univ. Helsinki

Overview of radiation damage mechanisms in materials

Harvesting energy from any particles with kinetic energies exceeding the energy of chemical bonds, i.e. energies above a few eV, raises the possibility that the particles introduce permanent damage in the materials used for the conversion. The…

Jan Hendrik Bredehöft

Dr. Jan Hendrik Bredehöft, Uni Bremen

Chemical reactions initiated by ionizing Radiation

Conventional wisdom has it that the chemical changes caused by ionizing radiation are due to the formation of radicals and their subsequent (re-)combination. This is especially true in the field of Astrochemistry, where ionizing radiation is the…

Karel Marsalek

Dr. Karel Marsalek, Institute of Aerospace Medicine, German Aerospace Centre

Development and use of active dosimeters for ionising radiation in space

Cosmic radiation is one of the limiting factors for long-duration space missions. For the assessment of radiation risk for humans DLR has been developing among others active radiation detectors for usage (i) onboard ISS, (ii)…

Judith Maschke

Judith Maschke, artec Sustainability Research Center, Uni Bremen

Changes in the energy consumption of private households due to the production and the use of renewable energies

In order to achieve the goals of the German energy transition changes in the energy consumption of private households are also required. In this context, efficiency, consistency and…
