Tracking the evolution of materials and interfaces in perovskite solar cells under an electric field
Stable performance is a key requirement for solar cell devices. Here, spectroscopy combined with depth profiling reveals I2 and PbI2 are distributed evenly in a perovskite solar cell under an electric field, while the electric field itself promotes chemical heterogeneity and device degradation.
