TREE-SCHOOL 2024

Group picture of the participants.

Scope and aim

This scientific school was part of an international drive to intensify research on thermophotovoltaic conversion. Typically, thermal radiation from a hot body at a temperature of between 700 and 2500 °C is converted into electricity by a photovoltaic cell operating in the infrared. The recent emergence of the thermophotovoltaic battery concept, based on the possibility of storing heat from various sources (industrial waste heat, concentrated solar energy, electrical energy from renewable energies during periods of low demand) at high volume density, presents the scientific community with numerous challenges, both theoretical and experimental, multidisciplinary and interdisciplinary, involving fundamental physical processes and coupling issues that cut across the elements and scales of the conversion system.
The aim of the school was to train researchers and engineers concerned with the scientific problems posed by the conversion of thermal radiation into electricity. This training should help participants to better identify unresolved scientific questions, and thus guide their research, within the collaborative framework of growing national and international communities.
