Perovskite solar cell containing Al-doped ZnO nanorod array and production method thereof

The invention discloses a perovskite solar cell containing an Al-doped ZnO nanorod array and a production method thereof. The cell comprises a transparent conductive substrate layer, an electron transport layer, a metal halide perovskite light absorption layer and a back electrode layer which are sequentially arranged from bottom to top. The electron transport layer is composed of a seed crystal layer, an Al-doped ZnO nanorod array layer and a passivation layer from bottom to top. The production method comprises the following steps: preparing the seed crystal layer on the transparent conductive substrate layer, preparing the Al-doped ZnO nanorod array layer on the seed crystal layer by an electrochemical deposition method, enabling the voltage to be-1.45 V to-1.55 V, keeping the deposition temperature to be 80 DEG C +/-3 DEG C, enabling the deposition time to be 10-30 minutes, and then preparing the passivation layer, the metal halide perovskite light absorption layer and the back electrode layer to obtain th
