The current–voltage curves of memristors exhibit significant hysteresis effects of use for
information storage and computing. Here, we provide a comparison of different devices
based on MAPbI3 perovskite with different contact configurations, from a 15% efficient
solar cell to a pure memristor that lacks directional photocurrent. Current–voltage curves
and impedance spectroscopy give insights into the different types of hysteresis,
photocapacitance, and inductance present in halide perovskites. It is shown that both
halide perovskite memristors and solar cells show a large inverted hysteresis effect at the
forward bias that is related to the presence of a chemical inductor component in the
equivalent circuit. Based on the results, we classify the observed response according to
recombination current in devices with selective contacts, to voltage-activated single-carrier
device conduction in devices with symmetric contacts. These findings serve to gain an
understanding of the mechanism of memristor currents in mixed ionic-electronic
conductors such as halide perovskites. We establish the link in the electrical response
between solar cells and memristors. [-]
