This research provides new insights into the identification of strain at the buried interfaces of perovskite thin films and reveals the strain-associated physical mechanisms impacting the performance and stability of perovskite solar cells.

Setfos was used to simulate the IV curve of perovskite cells with/without strain. They included the graded interface in the simulation and also the increased trap density.
