How thermophotovoltaics can help decarbonize the grid

Thermophotovoltaics (TPV) are a technology that can turn light into electricity, just like solar panels. However, instead of taking their energy from the sun, TPVs make use of the light emitted by a hot object in close proximity. We demonstrated a new record-breaking efficiency of more than 40% for TPVs, enabling the viability of this technology for ‘thermal battery’ energy storage.
