Trapping and recombination processes in thin films of CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> (MAPbI<sub>3</sub>) were studied by means of transient photoconductivity measurements and theoretical simulations of the relaxation curves resulting from the photocurrent measurements; in particular, the influence of temperature, as well as of the sample intensity of temperature illumination and pressure inside the measurement system on the photoconductivity response were studied.
