Investigation of defect‐tolerant perovskite solar cells with long‐term stability via controlling the self‐doping effect

SH Cho, J Byeon, K Jeong, J Hwang… - Advanced Energy …, 2021 - Wiley Online Library
Although there have been significant advances in the stability of perovskite solar cells
through encapsulation techniques to remove extrinsic degradation factors, such as moisture
and oxygen, irreversible photo‐degradation originating from intrinsic defects is still
challenging and remains elusive. Herein, the photo‐aging mechanism due to intrinsic
defects is investigated in nitrogen‐filled conditions, excluding extrinsic degradation factors.
Devices with similar power conversion efficiencies (PCE) of 21%, but with different Fermi …
