Electronic properties of perovskite lead-halide photovoltaic cells have been studied. The dc current/voltage characteristics were found to be well fitted by a standard diode equation under optical excitation and in the dark, while the impedance spectroscopy revealed a pronounced slow process under light illumination, which is absent in the dark. A simple model is proposed, which can explain all aspects of the observed behavior quantitatively and consistently.
