Main Scientific Interest

Thermoelectric ceramics for high-temperature power generation applications. Renewable energy candidates using waste heat sources capable to aid in the fight against global warming.

The Seebeck effect allows for the direct conversion of heat to electricity and it's exploited in solid state devices capable of using waste heat as a source for generating electrical power. Particular materials and strategies are designed and investigated with the final goal of producing state-of-the-art power generation technology using high-temperature (>400°C) waste heat sources.
