Long life of perovskite devices in working conditions remains the bottleneck for
technology application. Stable charge carriers’ transport together with nonreactive
contact materials contributes to the increase of the device operation time. Still, an
appropriate model for transport carrier mechanisms is needed because of the
complex ionic–electronic interplay. Herein, methylammonium lead bromide
perovskite single crystals are used to analyze the current flowing across the
perovskite sample after biasing. Two methods are performed: 1) direct measurement using an amperemeter and 2) indirect method by means of an induced
potential in a reference capacitor. Because of the continuity of the current, the latest
method measures direct current through the sample by monitoring displacements
currents. Intriguing features are observed: the displacement currents result in
stable and highly reproducible responses for long-term biasing (≈2000 s), while the
direct measurements produce larger and exponentially increasing current
dependence on time. These findings highlight the nontrivial effect of contacting
and measuring procedures in exploring thick perovskite electrical response. [-]
