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.
