Abstract

The invention discloses a perovskite nanofiber solar cell and a preparation method thereof. The light absorbing layer of the solar cell is a nanofiber film prepared by an electrospinning method using a polymer material as a complexing agent. The perovskite nanofiber The light-absorbing layer of the film is composed of a film with a continuous and dense structure formed by the interweaving of perovskite nanofibers. The perovskite nanofiber film prepared by electrospinning is used as the light-absorbing layer, which can increase the specific surface area of ​​the light-absorbing layer and enhance the light conversion efficiency of the solar cell. The agent can enhance the strength and continuity of the perovskite nanofibers, so that the material maintains high stability, thereby ensuring the stable performance of the solar cell.
