Abstract/Summary:

---

In recent years, Perovskite solar cells have been experiencing a fast increase in their efficiency. Therefore, regardless of their stability problems, Perovskite devices are poised to reach the commercial stage in a near future. Thus, the inclusion of mature processing techniques could become essential in order to reduce manufacturing costs, from the standpoint of large-scale production. The present paper summarizes the methodology followed and first results obtained by using screen printing techniques in a clean room environment, for providing the deposition of metallic contacts, for manufacturing perovskite solar cells. Different pastes and inks were analyzed throughout the research, looking for the best possible performance behaviors, by taking into consideration substrate-friendly and low temperature depositions processes. Thus, silver pastes and inks commonly used for contact metallization in other technologies were tested. Drying processes were performed at low temperatures, in short-time periods, in order to avoid damaging the molecular nature of the deposited layers. Finally, the quality of the resulting contacts was evaluated to establish the electrical properties.
