Poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) (PEDOT: PSS) is the most common and successful commercial conductive polymer used in the field of optoelectronics. Its properties are high transparency in the visible range, high electrical conductivity, excellent chemical and physical stability, high ductility, good film-forming properties, and high work function among the other polymers. PEDOT: PSS is highly hygroscopic in nature, which limits its applications. In the present work, the influence of moisture content due to hygroscopicity of the PEDOT: PSS thin film is in regard to the change of work function. Different modifications on the PEDOT: PSS which wants to lead to better compatibility in forming contacts with organic semiconductors.
