The study reveals that the dominant factor in the degradation of perovskite solar cells (PSCs) under operational conditions is mobile ion-induced internal field screening, significantly reducing efficiency mainly due to current density reduction, without major bulk or interface quality degradation.

How Setfos was used

Setfos was used to simulate the impact of increasing mobile ion density on PSC performance, demonstrating that higher ion density leads to enhanced internal field screening, reducing charge extraction efficiency and contributing significantly to early degradation losses in PSCs.
