Photoinduced large polaron transport and dynamics in organic–inorganic hybrid lead halide perovskite with terahertz probes
Ultrafast terahertz conductivity spectroscopy reveals the formation of large polarons in CH3NH3PbI3, which protects the charge carriers from scattering with polycrystalline grain boundaries or defects and explains the long lifetime.
