PEDOT / PSS, has been a well-known π-conjugated polymer. A number of studies have been so far reported on an improvement of its conductivity. However, a control of a surface roughness of PEDOT / PSS electrode has been rarely demonstrated, in spite of an important factor corresponding to device failure on OLED or OPV application. We previously reported that the conductivity of PEDOT / PSS was increased by an addition of a large amount of a certain salt into PEDOT / PSS. Based on the results, we tried to modify the substrate with the SAM bearing a same moiety as the salts. We wish to disclose that the PEDOT / PSS film deposited on the surface-modified substrate prevents the increase of the roughness of the surface with an increase of its conductivity.
