Conducting polymers display an ionic thermoelectric effect in addition to the known electronic thermoelectric effect. Their Seebeck coefficient is as large as ≈200 μV K−1. This finding discloses a new possible approach to improve the thermoelectric properties of conducting polymers by combining various types of charge carriers of the same sign.
