The invention belongs to the technical field of photovoltaic solar cells, and provides a flexible fibrous perovskite solar cell and a preparation method and application thereof. The solar cell comprises a fibrous working electrode and a fibrous counter electrode, wherein the fibrous working electrode comprises a carbon nanotube yarn, a hole transport layer constructed on the surface of the carbon nanotube yarn, and a perovskite composite layer constructed on the surface of the hole transport layer; the fibrous counter electrode comprises a carbon nanotube yarn and an electron transport layer constructed on the surface of the carbon nanotube yarn. According to the solar cell, the carbon nanotube yarn serves as an electrode substrate, and the solar cell has the advantages of being good in flexibility, small in density, high in interface bonding strength during loading and capable of being prepared continuously; meanwhile, the carbon nano tube yarn is prepared from the carbon nano tube fiber after structural des
