Degradation mechanisms of CH 3 NH 3 PbI 3 ‐based planar perovskite solar cells (PSCs) are investigated using a thermally stimulated current technique. Hole traps lying above the valence‐band edge of the CH 3 NH 3 PbI 3 are detected in PSCs degraded by continuous simulated solar illumination. One source of the hole traps is the photodegradation of CH 3 NH 3 PbI 3 in the presence of water.
