Unusual photophysical properties of organic–inorganic hybrid perovskites have not only enabled exceptional performance in optoelectronic devices, but also led to debates on the nature of charge carriers in these materials. This study makes the first observation of intense terahertz (THz) emission from the hybrid perovskite methylammonium lead iodide (CH3NH3PbI3) following photoexcitation, enabling...
Terahertz radiation is emitted from hybrid organic–inorganic perovskites following light absorption. This enables an ultrafast probing of the charge‐separation dynamics and carrier–lattice coupling, even under illumination conditions equivalent to 1 sun, as described by Burak Guzelturk, Aaron M. Lindenberg, and co‐workers in article number 1704737. Initial charge separation is shown to be diffusive...
