Engineered Doping of Organic Thermoelectric Materials

The role of substrates and electrodes in inkjet-printed PEDOT:PSS thermoelectric generators

“…Their electrical conductivity, however, is much lower but it may be increased by doping without a significant impact on the thermal conductivity. 15,16 In addition, organic semiconductors have the advantage of being light weight, flexible, and processable from solution. For these reasons, they represent a promising alternative for flexible and wearable devices 6,14,17,18 Among the different deposition techniques currently used for the deposition of organic semiconducting thin films, inkjet printing has become a promising technique not only in view of the easy device fabrication by solution-processing but also due to its relatively good spatial resolution, i.e., fabrication of a few tens of micrometers to large-area devices.…”
