Metal halide perovskites are promising light-harvesting components for future optoelectronic applications such as solar cells, light-emitting diodes, and photodetectors. The applicability of such devices is subject to the bound electron-hole pair (exciton) properties. In addition to the exciton generation and decay, one should also understand their transport and diffusion behavior. A double-path confocal fluorescence-lifetime imaging microscope (FLIM) visualizes exciton migration under ambient conditions. The separation of excitation and detection path enables a time- and space-resolved mapping of the excitons. This technique gives insight into the exciton dynamics, such as the diffusion type and the diffusion path.
