Thermophotovoltaic Cells (TPV)

Thermophotovoltaic cells absorb infrared radiation emitted by a high-temperature heat source and convert it directly into electricity. They work like solar cells, but use thermal radiation rather than sunlight.

  • Solid-state conversion with no moving mechanical parts
  • Compatible with high-temperature thermal storage and industrial waste heat systems
  • Engineering evaluation at device, package and module levels
How TPV Works

From Heat to Electricity

A heat source produces controlled high-temperature radiation. The TPV cell absorbs infrared photons matched to its bandgap and generates current, while system optics and thermal management can return unused photons to the source to improve overall energy utilization.

  1. 01Thermal Energy Input

    Electric heating, solar thermal energy, industrial process heat or another stable high-temperature source.

  2. 02Thermal Radiation Coupling

    A thermal emitter transfers stored energy to the cells as infrared radiation.

  3. 03Direct Power Generation

    Low-bandgap semiconductor devices convert matched photons into direct-current electricity.

Applications

Typical Applications

Thermal Storage to Power

Store electrical or renewable energy as heat and recover electricity through TPV modules when needed.

Industrial Waste Heat Recovery

Evaluate radiant heat recovery and power generation from high-temperature furnaces, reactors and continuous industrial processes.

Modular Solid-State Power

Integrate devices and packaging for compact, low-maintenance heat-to-power systems without rotating components.
