Advances in thermophotovoltaics: materials, devices and systems

An analysis of the scientific literature indicates a revival of research on thermophotovoltaics, boosted by the development of systems for converting waste or stored heat into electrical power. The symposium will provide an interdisciplinary platform for sharing the latest advances in the field.

Scope:

Thermophotovoltaics (TPV) refers to thermal to electrical power conversion based on the photovoltaic effect. It is suited for thermal sources operating at temperatures near or above 1000 K, such as waste or stored heat recovery, or solar energy conversion involving an intermediate thermal energy storage. Given the huge potentials of these systems, and recent progresses in high-temperature materials science, photonics, growth and processing of III-V semiconductors, a renaissance of research on thermophotovoltaics has taken place over the last decade. The challenges to tackle are indeed multiple, for designing, fabricating and testing new materials, devices and systems for TPV applications. In this context, the symposium will cover recent advances in areas relevant to the field: selective emitters to tailor the spectrum of radiation useful to photovoltaic conversion and their thermal stability; optimum materials and architectures of the photovoltaic cells and their fabrication and characterization; laboratory experiments assessing the performances of devices and systems; assessment of optical, electrical and thermal losses and their mitigation; new concepts for improving efficiency including hybridization with other thermal-to-electrical power converters; solar-TPV, TPV for space, near-field TPV systems; thermophotonic power generation and cooling, scaling-up of research prototypes. It is expected that the symposium will facilitate networking in this field through the establishment of exchanges across multiple disciplines in physics and engineering.

Hot topics to be covered by the symposium:

  • Tailored spectral thermal emission: photonic crystals, resonant emitters, metamaterials, etc.
  • Tailored spectral reflection and transmission: optical filters and reflectors, plasmonics, etc.
