Organometal halide perovskite has emerged as a promising material for solar cells and optoelectronics. Although the long diffusion length of photogenerated carriers is believed to be a critical factor responsible for the material's high efficiency in solar cells, a direct study of carrier transport over long distances in organometal halide perovskites is still lacking. We fabricated highly oriented crystalline CH3NH3PbI3 (MAPbI3) thin-film lateral transport devices with long channel length… 
Long Carrier Diffusion Length in Two-Dimensional Lead Halide Perovskite Single Crystals

Temperature and Gate Dependence of Carrier Diffusion in Single Crystal Methylammonium Lead Iodide Perovskite Microstructures.
TLDR
The observed highly non-local photocurrent and the rapid increase of carrier diffusion length at low temperature can be understood by formation and efficient transport of free exciton in the orthorhombic phase, as a result of reduced optical phonon scattering due to the dipolar nature of the excitons.
Visualization and Investigation of Charge Transport in Mixed‐Halide Perovskite via Lateral‐Structured Photovoltaic Devices
Mixed‐halide perovskites, CH3NH3PbI3−xClx, can be used to fabricate highly efficient perovskite solar cells; the presence of chlorine ions affects the perovskite morphology and enhances
