Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is the most successful commercialized conducting polymer. PEDOT:PSS is a mixture of two ionomers: positively-charged PEDOT and negatively-charged PSS. PEDOT is a conducting polymer, which has π-π conjugation in its main backbone, and PSS increases charge carrier density in PEDOT by removing electrons from PEDOT during the synthesis process. Many researchers have tried to increase the electrical conductivity, k, of PEDOT:PSS films and applied them to organic and metal halide perovskite optoelectronic devices as transparent electrodes. Recently, the electrical properties of PEDOT:PSS, including k and work function, have been optimized for those optoelectronic devices. Here, we review recent strategies for optimizing the electrical properties of PEDOT:PSS to use them as transparent electrodes.
Keywords:PSS;transparent electrode;conductivity;work function;optoelectronic devices
