Abstract
- Femtosecond transient absorption microscopy was applied to the elucidation of ultrafast dynamics in a lead iodide perovskite solar cell. Space- and time-resolved detection revealed that rapid deactivation with a time constant of 0.7 ps took place without long-living species in submicron grains with the (CH<subscript>3</subscript>NH<subscript>3</subscript>)PbI<subscript>3</subscript> capping layer, while the long-living component was detected in other areas.
