Nanoscale Impurities Degrade Halide Perovskites

For the first time, researchers in the UK and Japan have identified the locations where materials known as perovskites begin to degrade. This degradation, which is caused by the formation of defects that act as “traps” for charge carriers moving through the material’s crystalline structure, is a barrier to commercializing perovskite-based devices such as solar cells because it reduces their...
