What is a Thermophotovoltaic System?

The TPV system harnesses thermal radiations from different heat sources, such as fuel combustion, industrial waste heat, concentrated solar, or nuclear energy, and transforms them into electricity.A thermophotovoltaic (TPV) system is a good option to meet net-zero requirements. The thermophotovoltaic cell is the most important part of the TPV system.

Thermo-Photo-Voltaic Cell

A thermo-photo-voltaic (TPV) cell generates electricity from the combustion of fuel and through radiation. The fuel burns inside an emitting device that radiates intensely. Photo-voltaic (PV) cells—almost like solar cells—capture the radiation and convert it to electricity. The efficiency of a TPV device ranges from 1% to 20%.
