Fabrication of Skutterudite-Based Tubular Thermoelectric Generator

Energies, 2020
The conversion efficiency of the thermoelectric generator (TEG) is adversely affected by the quality of thermal contact between the module and the heat source. TEGs with the planar substrate are not suitable for the curved heat sources.

Asymmetrical Transport Distribution Function: Skewness as a Key to Enhance Thermoelectric Performance

Research, 2022
How to achieve high thermoelectric figure of merit is still a scientific challenge. By solving the Boltzmann transport equation, thermoelectric properties can be written as integrals of a single function, the transport distribution function (TDF).

Thermoelectrics

Materials Today, 2016
Metallic Ag microsphere in a ceramic matrix Thermoelectricity is the direct solid-state conversion between thermal and electrical energy, without any moving parts, due to the well-known Seebeck effect. Currently, more than half of the energy produced ends up in the form of wasted heat: thermoelectric harvesting and energy conversion constitutes an ...

Thermoelectric generation based on spin Seebeck effects

, 2016
The spin Seebeck effect (SSE) refers to the generation of a spin current as a result of a temperature gradient in magnetic materials including insulators. The SSE is applicable to thermoelectric generation because the thermally generated spin current can
