Abstract
The invention provides a preparation method of a solar cell using nanofibers as a perovskite layer passivation material. The perovskite solar cell comprises a transparent conductive layer, an electron transport layer, a perovskite photosensitive layer, a hole transport layer and a metal electrode layer, and is characterized in that the perovskite layer passivation material is nanofibers, and the nanofibers are prepared by an electrostatic spinning technology. The invention further provides the preparation method of the perovskite solar cell with the perovskite layer passivated by the nanofibers, the perovskite layer is prepared by adopting a method of spin-coating a mixed solution of the perovskite and the nanofibers, wherein the nanofibers can generate strong complexing and coordination effects with lead ions in the perovskite layer, so that electronic defects at crystal boundaries are filled up, and nucleation sites are provided for crystallization of perovskite to induce crystallization, and the energy conversion efficiency of the prepared perovskite cell reaches 20.3%.
