Perovskite is subject to ion migration — the movement of ions within the crystal lattice. When exposed to heat and light, electric fields from solar cell components cause ions within the ...

Although local defects in chloride-iodide-based perovskite are hard to avoid due to ion migration, a group of scientists have now found a way to passivate them. They used different combinations of ...

Perovskite solar cell degradation can be categorized as either intrinsic or extrinsic. Intrinsic degradation stems from material defects and ion migration, while extrinsic degradation results from ...
