Investigations on organic printed resistors based on PEDOT:PSS

The emerging of printed and organic electronics has been proven as a major trend in the last years. The only major commercial issue is represented by the organic light emitting diodes (OLED). In the current paper will be shown the results of electrical investigations of organic resistors based on poly(3,4-ethylenedioxythiophene) doped with polystyrenesulfonic acid (PEDOT:PSS). The influence of the track width and of aspect ratio is also investigated. The samples are prepared by ink-jetting, using two subsequent depositions, one is the silver termination and the second one is the active resistor material. It is expected that the results offer a guidance for organic resistor dimensioning and resistor overall parameters (rated power, temperature coefficient of resistance-TCR).
