Continuous acid-base treatment can achieve high thermoelectric performance for PEDOT:PSS film, but multiple surface treatments damage samples easily, lowering yield rates as well as increasing preparation costs, pre-venting its commercialization. To this end, we present an amphoteric salt-based post-treatment strategy for optimizing the charge transport properties and doping levels of PEDOT:PSS films, thereby achieving high elec-trical conductivity (a) and Seebeck coefficient (S) simultaneously. As a result, the optimal PEDOT:PSS thermo-electric film delivers a a of 1462 S center dot cm- 1 and...
