![]() These reduced states are delocalized across the polymer chain, and in the presence of the oxidizer, these radicalized states can be stabilized. The origins of this conductivity are due to the presence of radical states, which are formed due to the oxidation of the thiophene units. The electrical conductivity of oxidized polythiophenes has been known about for nearly 40 years. Frequently Asked Questions What Makes PEDOT:PSS Conductive? Once the surface is ready, a spin coater can be used to create a PEDOT:PSS thin film. This can be done using DI water, Hellmanex III, isopropyl alcohol and a UV Ozone Cleaner. Substrate surfaces should be prepared before the deposition of PEDOT:PSS to ensure that they are clean. In addition, in combination with metallic grid structures, sheet resistances comparable to metallic films are possible. PEDOT:PSS is a potential replacement for expensive transparent metal oxides such as ITO and FTO, and has been shown to be effective in both organic photovoltaic and perovskite photovoltaic devices. This include perovskite photovoltaics, organic photovoltaics, organic light emitting diodes, transparent conductors, organic electrochemical transistors, flexible electronics, thermoelectric generators, supercapitors, and energy storage PEDOT:PSS is the subject of a considerable amount of research, and is used for a range of applications within thin-film electronic fabrication. PEDOT Deposition with the Ossila Spin Coater (we recommend the use of a syringe pump) Applications We supply all our PEDOT:PSS solutions in light resistant bottles with temperature indicators. PEDOT:PSS typically comes as a water based emulsion which is created via the polymerization of PEDOT monomers in a polystyrene sulfonic acid solution. Similarly, a higher presence of PSS at the surface will result in a deeper work function. ![]() Since PEDOT is conductive and PSS insulating, the conductivity of the resulting polymer depends on ratio between these two ionomers and the microstructure of the film. The key properties of PEDOT:PSS are the extent to which it is conductive and the size of its work function. The properties of PEDOT:PSS vary from dispersion to dispersion, hence its versatility. ![]() Uses an alternative counter ionomer to PSS to allow for the dispersion in tolueneįor use with perovskite materials and whenever water-based dispersion is problematic
