제목 Study of Highly conductive PEDOT/PSS dispersion : efficient method for enhancing properties
초록 Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS), a conducting polymer showing high conductivity and transparency, is regarded as a promising material for electric devices because it enables cost-effective and flexible devices as well as roll-to-roll mass production. However, PEDOT:PSS yields a conductivity much too low to be used as an electrode. In this work, we demonstrated that purification to PEDOT:PSS solutions reduces thickness significantly. The insulating PSS and extra ion component on the PEDOT:PSS solution can be removed by purification. Finally, we obtained conductivity of PEDOT:PSS films up to 2000 S/cm Which is comparable to that of ITO. We also employed the optimized PEDOT:PSS films treated by purification as transparent anodes for ITO-free Organic photovoltaic cells fabricated on flexible substrates.
