Nanoscopic impurities trigger perovskite degradation

Improving the stability of perovskite solar cells requires an in-depth fundamental clarification on degradation mechanisms. Recently in Nature, Macpherson et al. unleashed the power of multimodal characterizations to elucidate the role of nanoscopic impurities in perovskites, which are found to induce active ion-photocarrier coupling that triggers degradation.

Automated summary

The role of nanoscopic impurities in perovskite solar cells, which induce degradation through active ion-photocarrier coupling, has been elucidated using multimodal characterizations.
