The Chemistry of Perovskite Solar Cells and Their Degradation Pathways

Quick fact

Perovskite solar cells have achieved power conversion efficiencies above 25% in just over a decade, yet they can degrade within hours when exposed to humid air, highlighting their extreme sensitivity to environmental conditions.

Why this is interesting

Solar cells that break efficiency records are made of a crystal that dissolves in water—how can that be?
