We examined different encapsulation strategies for perovskite solar cells by testing the device stability under continuous illumination, elevated temperature (85°C) and ambient humidity of 65%. The effects of the use of different epoxies, protective layers and the presence of desiccant were investigated. The best stability (retention of ∼80% of initial efficiency on average after 48h) was obtained for devices protected by a SiO2 film and encapsulated with a UV-curable epoxy including a desiccant sheet. However, the stability of ZnO-based cells encapsulated by the same method was found to be inferior to that of TiO2-based cells. Finally, outdoor performance tests were performed for TiO2-based cells (30-90% ambient humidity). All the stability tests were performed following the established international summit on organic photovoltaic stability (ISOS) protocols for organic solar cell testing (ISOS-L2 and ISOS-O1). ; Department of Electronic and Information Engineering
