The utility model relates to a solar cell. According to an existing perovskite cell, high temperature is needed by the production process, the use of the cell on a flexible substrate is limited, at the same time the efficiency is low, and lead is used in the perovskite cell and is harmful to the human body and environment. The utility model provides a tin perovskite structure flexible solar cell which comprises a conductive substrate, an anode, an electron transport layer, an absorbing layer, a hole transport layer and silver from the bottom to the top. The electron transport layer is a nano alumina film, and the absorbing layer is a tin perovskite structure absorbing layer. According to the tin perovskite structure flexible solar cell, the alumina is used as the electron transport layer, the tin perovskite structure is used as the absorbing layer, and the structure has the characteristics that the electron transport layer can be completed under the temperature of 150 DEG C, and the use of the lead is reduced at the same time.
