Fabricating semiconductor junction diodes can be costly in price and time. It typically involves long turn around time from the foundry, which requires precise machines and a clean room environment to prevent contamination from air born materials. This intensive process of fabricating diodes, means the cost will increase as the machines to process the semiconductor material need to become more precise. The proposed solution to the problem of cost and time is to create a printing system that is capable of printing diodes and circuits on various substrates. The experiments described in this thesis investigate the possible diode material, Poly(3,4-ethylenedioxythiophene), a polymer in aqueous dispersion. Variation in experiments with the weight ratios for the chemicals used for synthesis of this polymer are used as a benchmark to find the optimum weight ratios for the Poly(3,4-ethylenedioxythiophene) synthesis, to create an asymmetric rectifying diode, using continuous ink jet printing technology
