Degradation Mechanisms of Solution-Processed Planar Perovskite Solar Cells: Thermally Stimulated Current Measurement for Analysis of Carrier Traps

Degradation Mechanisms of Solution-Processed Planar Perovskite Solar Cells: Thermally Stimulated Current Measurement for Analysis of Carrier Traps

Degradation mechanisms of CH3NH3PbI3‐based planar perovskite solar cells (PSCs) are investigated using a thermally stimulated current technique. Hole traps lying above the valence‐band edge of the CH3NH3PbI3 are detected in PSCs degraded by continuous simulated solar illumination. One source of the...

Zusammenfassung:Degradation mechanisms of CH3NH3PbI3‐based planar perovskite solar cells (PSCs) are investigated using a thermally stimulated current technique. Hole traps lying above the valence‐band edge of the CH3NH3PbI3 are detected in PSCs degraded by continuous simulated solar illumination. One source of the hole traps is the photodegradation of CH3NH3PbI3 in the presence of water.
