Spatial localization of distinct photoexcited species were identified in light harvesting perovskite based materials using ultrafast transient absorption microscopy (TAM).

Researchers demonstrated that straining the crystal lattice of strontium cobaltite reduces oxygen content even under highly oxidizing conditions, enabling formation of functional oxygen defects at lower temperatures than previously possible.
