“…Thus, this type of encapsulation generally offers superior performance compared to thin film or flexible plastic encapsulation, although suitable selection of sealant is essential to ensure good lifetime. The use of various polymer materials instead of cover glass, including simple Kapton tape, with or without inclusion of nanomaterial to reduce WVTR, combined with UV curable adhesive has also been reported in the literature, ,, but this type of encapsulation has not been subjected to rigorous testing protocols, such as damp heat testing. Polymer cover materials are primarily of interest for flexible PSCs (for a detailed review of various barrier materials and encapsulation strategies applicable to flexible devices, see ref …”

“…Furthermore, additional features can be introduced when polymeric materials are used for encapsulation which can be beneficial for device performance. For example, the use of UV curable optical adhesive also enables the possibility of using micropatterning to increase the water contact angle, and such micropatterned surfaces can also be used on the substrate to decrease reflection losses . Additional features which can be incorporated include the inclusion of a phase change material, such as poly(ethylene glycol) (PEG), into the resin to improve thermal management of the device, which in turn results in prolonged lifetime .…”

“…Other nonconventional tests involve water immersion for varying periods of time, ,,,,,,− from 1 min to 4 days, and annealing at higher temperatures compared to standard tests . A stability test with placing water on encapsulated surface of a PSC was also reported, , and the results were strongly dependent on the type of encapsulation.…”

With the progress in the development of perovskite solar cells, increased efforts have been devoted to enhancing their stability. With more devices being able to survive harsher stability testing conditions, such as damp heat or outdoor testing, there is increased interest in encapsulation techniques suitable for this type of tests, since both device architecture compatible with increased stability and effective encapsulation are necessary for those testing conditions. A variety of encapsulation techniques and materials have been reported to date for devices with different architectures and tested under different conditions. In this Perspective, we will discuss important factors affecting the encapsulation effectiveness and focus on the devices, which have been subjected to outdoor testing or damp heat testing. In addition to encapsulation requirements for these testing conditions, we will also discuss device requirements. Finally, we discuss possible methods for accelerating the testing of encapsulation and device stability and discuss the future outlook and important issues, which need to be addressed for further advancement of the stability of perovskite solar cells.

“…For achieving long lifetime, a high level of encapsulation is required. Stability of perovskite solar cells was improved by employing Norland Optical Adhesive/ polyethylene Terephthalate (NAO/PET) as moisture barrier layer is reported [14]. The PSCs encapsulated by NOA/PET show stability under approximately 54O h exposure to moisture.…”

Perovskite-based solar cells have attracted a great deal of attention due to their rapid increase in power conversion, which has reached to 24.2%. The performance of perovskite solar cells depends on several parameters such as the absorber layer, the electron transport layer, the hole transport layer, and the electrodes, and the deposition technics. Moisture, oxygen, tem-perature and light intensity are environmental factors which can influence the stability of the photovoltaic devices and dete-riorate the performance. Also, the toxicity, caused by the presence of lead (Pb) content, is an obstacle for the commerciali-zation of the perovskite solar cells. The use of free-lead absorber layer is discussed, and solution to improve performances and stability of perovskite solar cells are proposed.
