Symposium 2021

Beyond solar cells: new approaches to radiation conversion

MAPEX Symposium 2021: 29 - 30 September 2021

This online workshop aims at bringing together expertise on alternative sources, techniques and materials for radiative energy conversion beyond conventional solar cells. It addresses a wide range of applications including space technologies, radiation therapy, clean energy generation and more.

The workshop will comprise

  • invited talks by internationally renowned speakers

  • poster contributions, including a short oral presentation in advance in dedicated pitch sessions and poster awards for the best presentations

  • an informal live meeting on Wednesday afternoon in Bremen, if the pandemic situation allows.

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…

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…

Aims and Scope

Harvesting sunlight with semiconductor-based solar cells is without a doubt one of the most important technologies to tackle energy generation as an alternative to or in the absence of fossil fuels. As such, energy-conversion devices such as photovoltaics are critical for generating electricity both to achieve the energy transition on earth as well as for space applications. While electromagnetic radiation from the sun constitutes the major source of convertible radiative energy, other types of radiation can potentially be harvested as well. This includes proton radiation from the sun, radiation from nuclear waste or other types of ionizing radiation. Likewise, conventional solar cells can be substituted or supplemented by alternative energy conversion devices like organic or perovskite solar cells, betavoltaic cells or other advanced materials that interact with ionizing radiation in a predictable and usable way.
