Perovskite battery itself is a capacitor

Here, self-powered photodetection (SPD) of perovskite SCs based on capacitance effects is reported when the capacitor releases its previously stored electric power by discharging operations. The capacitive results are highly in accord with numerical simulations of dielectrics, rather than the common ion migration.
