“…Successful encapsulation typically does not result in significant changes of efficiency after encapsulation. , For example, ∼19.2% average efficiency was obtained for 16 cells before and after encapsulation, with the best device exhibiting 19.9% PCE efficiency before 19.7% efficiency after encapsulation . In tandem cells, some drop in the efficiency can occur after encapsulation due to front glass reflection, but this mechanism is not applicable to individual PSCs which are typically illuminated through the same glass substrate before and after illumination.…”

“…An exception is fluoropolymer coating (on top of the perovskite and back surface of the glass), where the devices were subject to outdoor testing in addition to exposure to high humidity (95%) environments, and ∼500 nm thick spray-coated reduced graphene oxide (rGO) film encapsulation, where the devices were subjected to damp heat testing . The situation is similar for inorganic thin film encapsulation, where the majority of reports show stability for ambient storage with some exceptions reporting nonstandard accelerated aging conditions (shelf life at 50 °C, 50% RH) and rarely considering harsh testing conditions, such as damp heat 85 °C, 85%RH and outdoor testing . Nevertheless, it is likely that thin film encapsulation combined with the cover glass/cover sheet encapsulation , can yield significantly improved performance.…”

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.

3D printing, also known as additive manufacturing, is a manufacturing process in which the materials are deposited layer by layer in an additive manner. With the advancement in materials and manufacturing technology, 3D printing has found its applications in the field of electronics manufacturing. Initially, 3D printing is used for the fabrication of electronic components with single material designs such as resistors, inductors, circuits, antennas, strain gauges, etc. Recently, there are many works involving the use of 3D printing fabrication techniques for advanced electronic components and devices such as parallel plate capacitors, inductors, organic light‐emitting diodes, photovoltaics, transistors, displays, etc. which involve multilayer multimaterial printing. Despite these many works, there has been no review on the design and fabrication consideration for the 3D printing of multilayered and multimaterial (MLMM) electronics. As such, this review aims to summarize the current landscape of 3D printing of MLMM electronics and provide some insights on the design consideration, fabrication strategies, and challenges of 3D printing of MLMM electronics. In particular, the focus will be placed on discussing the interface conditions between different materials such as surface wettability, surface roughness, material compatibility, and the considerations for postprocessing treatments.

Despite attractive cost‐effectiveness, scalability, and superior stability, carbon‐based printable perovskite solar cells (CPSCs) still face moisture‐induced degradation that limits their lifespan and commercial potential. Here, the moisture‐preventing mechanisms of thin nanostructured super‐repellent coating (advancing contact angle >167° and contact angle hysteresis 7°) integrated into CPSCs are investigated for different moisture forms (falling water droplets vs water vapor vs condensed water droplets). It is shown that unencapsulated super‐repellent CPSCs have superior performance under continuous droplet impact for 12 h (rain falling experiments) compared to unencapsulated pristine (uncoated) CPSCs that degrade within seconds. Contrary to falling water droplets, where super‐repellent coating serves as a shield, water vapor is found to physisorb through porous super‐repellent coating (room temperature and relative humidity, RH 65% and 85%) that increase the CPSCs performance for 21% during ≈43 d similarly to pristine CPSCs. It is further shown that water condensation forms within or below the super‐repellent coating (40 °C and RH 85%), followed by chemisorption and degradation of CPSCs. Because different forms of water have distinct effects on CPSC, it is suggested that future standard tests for repellent CPSCs should include rain falling and condensate formation tests. The findings will thus inspire the development of super‐repellent coatings for moisture prevention.
