Temperature-dependent charge-carrier dynamics in CH3NH3PbI3 perovskite thin films
The photoluminescence, transmittance, charge-carrier recombination dynamics, mobility, and diffusion length of CHExpand abstract
3NH 3PbI 3are investigated in the temperature range from 8 to 370 K. Profound changes in the optoelectronic properties of this prototypical photovoltaic material are observed across the two structural phase transitions occurring at 160 and 310 K. Drude-like terahertz photoconductivity spectra at all temperatures above 80 K suggest that charge localiz...
