A further step has been carried out in order to produce an ink formulation for screen printing purposes capable of providing contacts compatible with perovskite substrates. This has been achieved by developing a mixed binder, comprised by epoxy resin and collodion that produces perovskite-friendly contacts that present an average volumen resistance of 2.282 Ω • cm, with a standard deviation of 1,621 Ω • cm. Although these results represent a slight improvement over those obtained previously, these have not made a sufficiently representative difference to continue along this line of research without considering the implementation of significant alternatives. In this sense, the paper concludes with the logic behind intruducing carbon black in our ink formulations.
