Organic Thermoelectrics

  • Thermoelectrics emerged as a solid state technology to harvest usable electrical power from waste heat.

  • Typically, conventional thermoelectric devices are of inorganic materials and perform at high temperature over 200 ℃.

  • However, organic semiconductor-based thermoelectric devices (OTEs) showed a potential of near-room-temperature applications by their relatively high power factor at room temperature.

  • Furthermore, organic semiconductors can be applied to flexible devices, since they have major merits compared with their inorganic counterparts, not only low-cost processability, but also mechanical flexibility.

  • We aim to increase electrical conductivity, which is the key for further developing of OTEs, for enhancing thermal power conversion efficiency.
