TL;DR: Photoluminescence, transient absorption, time-resolved terahertz and microwave conductivity measurements are applied to determine the time scales of generation and recombination of charge carriers as well as their transport properties in solution-processed CH3NH3PbI3 perovskite materials to unravel the remarkable intrinsic properties of the material.

Photoinduced Ultrafast Dye-to-Semiconductor Electron Injection from Nonthermalized and Thermalized Donor States.
TL;DR: It is shown that the dominating part of the electron transfer proceeds extremely rapidly from the initially populated, vibronically nonthermalized, singlet excited state, prior to electronic and nuclear relaxation of the molecule.
