Main Scientific Interest

Thermoelectric oxide composites for waste heat recovery. Renewable energy candidates to the "European Green Deal".

The Seebeck effect allows for the direct conversion of temperature gradients into electricity and it's exploited in solid state devices capable of using waste heat sources for generating electrical power. Novel composite materials are designed and investigated for producing state-of-the-art power generation technology using industrial high-temperature (>400°C) gasses as fuel.
