A transparent electrode is an indispensable component of optoelectronic devices, and there as been a search for substitutes indium tin oxide (ITO) the electrode. Poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate) (PSS) conducting polymer that very promising next generation materials if it can obtain conductivity high ITO. Here, we report treatment ofPSS with organic solutions to significantly enhance its conductivity. Common solvents like dimethylformamide γ-butyrolactone common salts methylammonium iodide bromide are used solutions. The pristinePSS films only ∼0.2 S/cm, be increased higher than 2100 S/cm. enhancement much more significant control treatments neat or aqueous salts. mechanism synergetic effects both on microstructure composition ofPSS. They induce segregation some PSSH chains fromPSS. Highly conductivePSS were studied solar cells. photovoltaic efficiency comparable ITO
