This review describes three recent developments in ultrafast transient absorption
spectroscopy that have revealed new insights into the dynamics of photogenerated charge …

The ability to study single particles has revolutionized nanoscience. The advantage of single
particle spectroscopy measurements compared to conventional ensemble studies is that …

We use ultrasensitive electron backscatter diffraction (EBSD) to map the local crystal
orientations, grains, and grain boundaries in CH 3 NH 3 PbI 3 (MAPI) perovskite thin films …

Low-temperature processing in perovskite films always results in the formation of
submicrometer scale grains and consequent abundant defects that lead to carrier …

We use correlated confocal and wide-field fluorescence microscopy to probe the interplay
between local variations in charge carrier recombination and charge carrier transport in …

Organic–inorganic hybrid perovskite materials have recently evolved into the leading
candidate solution-processed semiconductor for solar cells due to their combination of …

In this review, the recent progress in using transient absorption microscopy to image charge
transport and dynamics in semiconducting hybrid organic–inorganic perovskites is …

Multimodal chemical imaging simultaneously offers high-resolution chemical and physical
information with nanoscale and, in select cases, atomic resolution. By coupling modalities …

Halide perovskites have remarkable properties for relatively crudely processed
semiconductors, including large optical absorption coefficients and long charge carrier …

Nonlinear optical (NLO) microscopy relies on multiple light–matter interactions to provide
unique contrast mechanisms and imaging capabilities that are inaccessible to traditional …
