Stabilizing perovskite solar cells—researchers decouple the synergistic role of water and oxygen in degradation

By Lisa McDonald / February 20, 2024

Achieving long-term operational stability of all-perovskite solar cells remains a challenge. Researchers led by Georgia Institute of Technology made the surprising discovery that while exposing perovskites to both water and oxygen leads to instability, taking away one of those factors preserved the perovskites’ structure.
