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…

Electrospun Polyimide Ultrafine Fibrous Membranes with Enhanced Atomic-Oxygen Resistance via Incorporation of POSS Components: Preparation and Properties

Polyimide (PI) represents a class of important materials in various space applications due to their high thermal resistance, good dielectric and…

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…

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…

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…

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…

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…

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…

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)…

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…
