This paper presents measurement of the relative permittivity (εr) of PEDOT-PSS films by measuring the capacitance at metal semiconductor junction. PEDOT-PSS films with and without contact resistances were investigated and it was observed that relative permittivity of the PEDOT-PSS films at low frequencies without contact resistance was large as 5143 and in presence of contact resistances it was 41838 which is 8 times more than the relative permittivity obtained without contact resistance. Such materials with mega permittivity are suitable to build super capacitors.
