Resumen

In this work, new advances in the research conducted by the solar cells laboratory (SiCelLab) from the Instituto Tecnológico y de Energías Renovables (Canary Islands, Spain) in order to develop inks for screen printing metallization, based on the use of epoxy resin and anhydrous solvent vehicles are presented. This approach has been designed to be applied on thin film perovskite substrates. The methodology applied makes use of an overhead stirrer for mixing and a three roll mill for homogenizing the ink components. From the developed inks, samples have been printed with average volume resistivities measured as low as 3.31 Ω·cm. Preliminary results suggest that a further reduction on these values is possible by way of including a co-binder species that allows reducing the amount of epoxy resin within the mix.
