Cryogenic spatial–temporal imaging of surface photocarrier dynamics in MAPbI3 films at the single grain level
We use cryogenic spatial–temporal photoluminescence (PL) imaging measurements down to 10 K and with short-wavelength, 405 nm laser excitation to study surface charge generation, trapping, and recombination at single bright and dark grains as well as their boundaries in model methylammonium lead iodi...
