ABSTRACT
Polymer electronics shows the possibility to build flexible devices. Conducting polymer poly(3,4-ethylenedioxythiophene) doped with polystyrene sulfonic acid (PEDOT-PSS) was widely used as interfacial layer or polymer electrode in polymer electronic devices, such as light-emitting diodes (LEDs) and photovoltaic devices (PVDs). In this chapter, the applications of PEDOT-PSS used as buffer layer and anode in polymer devices were briefly reviewed. The important properties for its application in polymer PVDs, such as conductivity, the optical properties, and work function were discussed. The applications of PEDOT–PSS in polymer PVDs as a buffer layer or transparent electrode were demonstrated.
