Abstract

Abstract : This cover image illustrates a transient microscopy measurement of the excited state energy transport in a perovskite lattice. An initial Gaussian population of excitations flows outwards, here illustrated by the flow of water. The energy transport is obstructed by defects along the way and transient microscopy measurements can therefore be used to accurately map out the trap‐state landscape in the perovskite lattice.
