N2 - We report on position-dependent measurements of photocarrier transport using time-resolved terahertz spectroscopy (TRTS) across a slot-die printed perovskite film of varying morphology. Using the Drude-Smith model for the photoconductivity spectra we report maximum intrinsic mobilities of 540 \pm 20cm2 V-1 s-1. In addition, we measure variation across the film in the extracted mobilities and the localization c-parameter, correlated with complementary measurements of the film morphology and optical properties. To the best of our knowledge this is the first TRTS study performed on perovskite films produced using a slot-die printing technique.
