Resumen

This document summarizes the work that has been carried out in order to develop a mixed binder, comprised by epoxy resin and ethylene-vinyl acetate (EVA), for produce ink vehicles for screen printing purposes, that can be used for depositing back contacts on perovskite solar cells, as an alternative from thermal evaporation. Three ink formulations are described, as well as the procedures and requisites for developing them. These inks were used to produce contacts over glass substrates via screen printing techniques and the contact were electrically characterized in order to assess their conductivity. Although the champion ink produced contacts with a volume resistivity of 2.36 Ω•cm, which means a slight improvement from previous results published by our group, further research would be required in order to reduce screen clogging during the printing process, and to increase the contact’s adherence to the substrates.
