In article number 1700977, Yana Vaynzof and co-workers investigate how the MAPbI3 perovskite layer microstructure is affecting its stability upon exposure to oxygen and light. The authors show that the degradation processed is initiated at the grain boundaries, demonstrating that devices whose active layer consists of larger, more uniform grains exhibit enhanced photovoltaic stability.
