Light-activated photocurrent degradation and self-healing in perovskite solar cells

Organometallic perovskite solar cells exhibit good efficiency but their photostability is still relatively poorly understood and controlled. Here the authors show that photo-degradation arises from the formation of light-activated meta-stable trap states, is reversible, and can be frozen at 0 °C.
