Preparation method of perovskite solar cell module

The invention discloses a preparation method of a perovskite solar cell module. Comprising the following steps: S1, providing a transparent substrate; s2, plating a transparent conducting layer on the substrate, and performing p1 scribing on the conducting layer to form a p1 groove channel; s3, placing an integrated mask plate on the conductive layer, and plating a hole transport layer on the conductive layer; the integrated mask plate comprises a region A and a region B; s4, annealing/drying the hole transport layer, and plating a perovskite absorption layer on the hole transport layer; s5, annealing/drying the perovskite absorption layer, and plating an electron transport layer on the perovskite absorption layer; s6, annealing/drying the electron transport layer, and taking down the A region of the integrated mask plate to form a p2 groove channel; s7, forming an electric connection layer and a p3 groove channel on the electron transport layer by using the integrated mask plate B region; and S8, annealing/d
