Preparation method of perovskite solar cell and perovskite solar cell

The invention provides a preparation method of a perovskite solar cell and the perovskite solar cell. The perovskite solar cell comprises a substrate, a hole transport layer, a perovskite light absorption layer, an electron transport layer and a transparent conductive electrode layer which are arranged in sequence, an organic linear evaporation source is utilized to scan and evaporate fullerene on the perovskite active layer to form a fullerene layer so as to form an electron transport layer, and the linear evaporation source adopts a mode of fixing the evaporation source and moving a sample substrate back and forth in parallel, so that better deposition uniformity, higher film purity and higher material utilization rate can be realized; the method has positive significance in improving the performance of the perovskite solar cell module and promoting the commercial mass production of the perovskite solar cell module. 本申请提供的钙钛矿太阳能电池的制备方法及钙钛矿太阳能电池，包括：依次设置的衬底、空穴传输层、钙钛矿光吸收层、电子传输层以及透明导电电极层，在所述钙钛矿活性层上利用有机线性蒸发源扫描蒸镀
