The invention discloses a non-temperature-resistant flexible perovskite solar cell and a preparation method thereof, and belongs to the field of solar cells. The cell sequentially comprises a flexible substrate, a transparent conductive functional layer, a hole transport layer (1), a hole transport layer (2), a perovskite light absorption layer, an electron transport layer, a hole barrier layer and a metal electrode layer from top to bottom. The hole transport layer (2) is prepared by combining a semiconductor cooler device and a heating stage. The preparation method comprises the following steps: (1) spin-coating VNPB; (2) adhering one surface of a flexible battery substrate to the cold end of the semiconductor cooler, and exposing the surface of the flexible battery substrate subjected to spin coating of VNPB in the air; and (3) the cold end of the semiconductor cooler is reversely buckled on a high-temperature hot stage, at the moment, the VNPB layer directly faces the hot stage, and hot air of the hot sta
