Summary

Hybrid or composite thermoelectric (TE) materials, combining the low thermal conductivity of an organic material and the high Seebeck coefficient and electrical conductivity of other compounds, have been developed. Thus, the resulting hybrid/composite TE materials exhibit an unpredictable TE performance through advanced percolation phenomena, the interface effect, the energy filter effect, etc. In this chapter, we provide an overview of the fundamentals, recent developments and the optimization strategies of hybrid/composite OTE materials. This chapter will provide readers with basic knowledge of hybrid/composite OTE materials and a guideline toward materials design with high TE performance.
