“…Photodetectors have been developed for a variety of promising applications, like optical detections, environmental monitoring, day/night surveillance. [1][2][3] Nowadays most commercial available photodetectors are typically based on traditional semiconductors like Si and InGaAs. However, the traditional materials it is significantly faster than the multilayer devices like PSC (HTL/perovskite/ETL).…”

This work presents two different encapsulation strategies for perovskite photodetectors by testing the device stability under elevated ambient humidity of 85% and room temperature (25 °C). The single layer structure is adopted in the devices in order to accelerate the aging tests. The best stability (retention of ≈90% of initial photoresponsivity on average after 24 h, and ≈73% after 168 h) is obtained for devices protected by a flexible UV‐curable resin shell and encapsulated with AB epoxy including a desiccant sheet. The effects of the epoxy outgassing, the presence of desiccant, and the bending ability of encapsulated devices are also investigated. Additionally, with the assistance of 3D printing technology, a new possibility of research in the aspect of electrical device encapsulation is developed. Rapid iterative modifications in materials, shape, inner structure, and easy integration with outer component like desiccant ball/sheet make 3D printing assistance an ideal solution for the design of the encapsulation configuration and its early verification. This work not only opens up an optimal way for perovskite encapsulation by the 3D printing technology, but also provides an ideal solution for the design of the encapsulation configuration and its early verification.
