What are Thermophotovoltaics?

What are thermophotovoltaics? Thermophotovoltaic cells are a member of the larger photovoltaic cell family, the most famous of which are the popular solar cells. Each type of photovoltaic cell specializes with a certain bandwidth of light frequencies from which to most effectively draw power. In solar cells, these are designed to match the frequencies of light which the surface of the Earth receives from the Sun.


Thermophotovoltaics (TPVs) are specially designed to convert energy from the infrared region of the electromagnetic spectrum. This is most commonly given off by heat, and so TPVs may be said to convert heat to energy. All types of photovoltaics have their advantages, and those of TPVs are their ability to operate independent of weather or time of day, as well as generating energy nearly silently and without the need for maintenance.

JX Crystals uses state-of-the-art Gallium Antimonide (GaSb) cells, originally developed at Boeing, to achieve this feat. As an industry leader for nearly three decades, JX Crystals currently works primarily with large military R&D contracts.
