There are many researches on PEDOT:PSS treatment for application to flexible device electrode. Almost PEDOT:PSS treatment is consisted with step adding little bit surfactant to enhancement of adhesion between PEDOT:PSS and substrate or TCO materials. But basic research about surfactant effect is lacking. We study on the effects of sodium dodecyl sulfate (SDS) with controlling the concentration in aqueous PEDOT:PSS solution, and we confirm the conductivity enhancement of the mixture thin films with surfactant and PEDOT:PSS. Thin films are firstly prepared by spin coating method and then fabricated organic solar cells. To study the structural effects on the resulted electrical properties, thin films are mainly investigated by FE-SEM (Field Emission Scanning Electron Microscopy), AFM (Atomic Force Microscopy), respectively. At the same time, electric properties are also investigated by both 4-point probe and solar simulator.
