Photovoltaic energy is currently drawing attention as an upcoming alternative energy source, and perovskite solar cells hold promise for next-generation photovoltaic devices due to their remarkable optical properties, high light-absorption coefficient and good cost-effectiveness. However, these materials are still afflicted with long-term stability and reliability issues. To commercialize this device, understanding of its mechanical behavior is of high priority. Many researchers have attempted to solve its stability issues, but information on its mechanical properties is still insufficient. For this reason, we fabricate free-standing component thin films of perovskite solar cells and evaluated their elastic properties using in-situ nanoindentation tests on hole-substrates. We confirmed that the perovskite layer is most fragile layer among all components. Therefore, we evaluated and analyzed the intrinsic tensile properties of perovskite layer by in-situ tensile testing using push-to-pull devices. We believe that this study sheds light on the durability and fundamental mechanisms of the material.
