We describe a fast, simple and low temperature electrochemical technique for the preparation of zinc oxide
layers on rigid and flexible substrates. The layers, prepared from a zinc nitrate precursor, are of high
structural and optical quality. They have been optimized to be applied as efficient electron transport
layers in CH3NH3PbI3-sensitized perovskite solar cells (PSCs). We show that an electrodeposition time of
only two minutes and a low processing temperature are sufficient to fabricate solar cells with a power
conversion efficiency close to 11%, with a high short circuit current and a small J–V curve hysteresis. The
key parameters of the cell functioning have been analyzed over a large applied voltage range by the
impedance spectroscopy technique. The solar cell characteristic changes with the ZnO layer deposition
time are explained by the variation of the recombination and charge transfer resistances. [-]
