Application fields
I. Fuel cells:
Develop electrodes with long-term stability with low precious
metal load by better understanding aging mechanisms
II. Catalysts for energy technology:
Develop immobilized, functional nanoparticles for
photo-catalytic water dissociation, improving photo-catalysis
III. Battery technology:
Develop anode materials with high storage capacity
of >1500 mAh/g based on Si / C nanocomposites
IV. Photovoltaics:
Reduce the number of process steps and processing temperature of Si-based
photovoltaics using highly doped Si nanoparticles and laser sintering
V. Thermoelectric generators:
Develop thermoelectric materials based on Si and SiX nanocomposites.
Unlike the Pb, Te, and Sb compounds typically used so far, Si-based
systems are non-toxic and uses abundant raw materials
