Performance Decrease of Perovskite Solar Cells

(A)The evolution of dark current characteristic curves.

(B) The evolution of electrochemical impedance.

(C) The evolution of VOC decay.

(D) The evolution of Transient JSC (normalized at maxima). These PSCs were exposed to UV irradiation in an argon-filled glovebox at room temperature. Complex impedance plot for PSCs measured in dark condition at short circuit conditions.
