In recent years, flexible organic and perovskite photovoltaic devices, organic thin-film transistors and medical sensors have been become popular fields of scientific research due to their advantages of wearable, flexible and semi-transparent properties. Employing conductive polymer with excellent mechanical properties is one of the effective pathways to realize these high-performance devices. In conducting polymers, poly(3,4-ethylenedioxythiophene) (PEDOT) and its aqueous dispersion poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) have been demonstrated to be the most promising alternative flexible materials of conventional metal oxides. It can be used as transparent electrode, hole transport layer, interconnects, electroactive layer, or motion sensing conductor in the device. This review focused on recent research advances of flexible devices for PEDOT and PEDOT:PSS applications, including various strategies to improve electrical conductivity, mechanical tolerance and long-term stability, and reveals the potential mechanisms of performance enhancement.
