Abstract: (1563 Views)
High sensitivity to ambient moisture and oxygen is one of the most important challenges in perovskite solar cells (PSCs), which reduces the devices lifespan. In this regard, an encapsulation method has been developed for PSCs. Encapsulation is the application of a non-reactive substance around the device, which prevents the penetration of oxygen and moisture. this method includes placing a thin layer of polymeric materials such as PMMA, EVA and PC, then glass cover and finally using epoxy adhesive. After encapsulation, the samples were subjected to 90% humidity and 40 °C temperature for 10 hours. It was observed that the cell efficiency under the mentioned conditions decreased by only 1.96%.
