Abstract Scope |
The long-term stability of perovskite solar cell has been one of the main concerns regarding the up-scaling of this technology. In this work, we develop a simple, fast and green method to encapsulate perovskite solar cells maintaining the optoelectronic properties over 300 days after water immersion. The use of a photo-curable monomer offers a fast encapsulation as well as avoid the need of any solvent that could degrade the perovskite layer. Electronic characterization of the devices (J-V curves, IPCE and Impedance Spectroscopy) did show barely changes in the sample's behaviour. In addition, encapsulated samples kept 80% of their initial PCE after ageing test with several environmental conditions. This encapsulation process will contribute to the development of both extraordinarily efficient and stable solar cells. |
