TLDR
The accumulation of mobile ions causes space charge at interfaces in perovskite solar cells, and the dynamic process of the interface charge governs the current-voltage hysteresis.Abstract:
The accumulation of mobile ions causes space charge at interfaces in perovskite solar cells. There is a slow dynamic process of ion redistribution when the bias is changed. The interface charge affects band bending and thus the photocurrent of the solar cells. Consequently the dynamic process of the interface charge governs the current-voltage hysteresis. Very low interface charge density leads to hysteresis-free devices.read more

TL;DR: It is found that varied PSC responses are attributable to two causes, capacitive effect associated with electrode polarization provides a slow transient non-steady-state photocurrent that modifies the J-V response, and modification of interfacial barriers induced by ion migration can modulate charge-collection efficiency so that it causes a pseudo-steaden state photocurrent.
