Description

Charge extracting layers play a key role in the elimination of hysteresis from J–V characteristics of inverted hybrid perovskite solar cells. Methanofullerene electron extracting layers stabilize short‐circuit photocurrents from the very first J–V scan, while preconditioning cycles are needed to stabilize the open‐circuit voltage owing to interaction between migrating iodide ions and the charge extraction layer.
