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 hole traps is the photo-degradation of CH3NH3PbI3 in the presence of water.
