A New Thermoelectric Material Has Been Created That Makes Use Of Heat To Create Power

Thermoelectric materials have the ability to generate energy from the difference in temperature between two surfaces. Organic thermoelectric materials may be used to power a variety of things, including wearable electronics and sensors. It’s important to note, however, that the amount of electricity generated by these materials is extremely modest.

At the University of Groningen, a team of researchers has created an n-type organic semiconductor. Wearable electronics are one step closer to having high power output thanks to the semiconductor’s exceptional characteristics.

The thermoelectric generator, launched in 1977 aboard both Voyager space probes, is the sole man-made power source outside our solar system. These thermoelectric generators, which use generators to convert heat into electric current, are presently in interstellar space. It is notable that these thermoelectric generators have no moving components, making them solid-state devices.

An inorganic thermoelectric material’s brittleness and rigidity are some of its downsides.

Inorganic thermoelectric materials, on the other hand, include hazardous or rare elements. As a result, the thermoelectric material employed in Voyager’s generators is not appropriate for everyday usage. Because of this, they are often hard and brittle. Developing organic thermoelectric materials is growing in popularity as a result of this fact. There are issues with using organic thermoelectric materials as well.

Phonon glass is one of the best thermoelectric materials available. A poor heat conductivity and a high electrical conductivity electron crystal are two of its notable features. Furthermore, organic semiconductors have a difficulty with limited electrical conductivity.

While working on organic photovoltaic materials for over a decade, a group at the University of Groningen has pioneered an organic thermoelectric material that is superior. n-type semiconductors with negative charges were the primary focus of the team.
