Annotation	Using two different techniques, Fourier-transform photocurrent spectroscopy (FTPS) and photoluminescence (PL), we have probed the temperature dependence of methylammonium lead iodide (MALI) absorption spectra to be able to distinguish the static and dynamic part of Urbach energy. We extract the Urbach energy as the reciprocal value of the slope of the absorption at the band edge plotted in logarithmic scale. Its value depends on the material disorder and generally correlates well with the loss in the open-circuit voltage (VOC) of optimized cells, compared to their bandgap, for a given photovoltaic technology.
