Abstract

The invention discloses an FK102 ligand modified perovskite solar cell and a preparation method of a perovskite layer thereof. The perovskite solar cell comprises an electron transmission layer, perovskite, a hole transmission layer and an electrode, wherein a material forming a modification layer is selected from an FK102 ligand. By the interface modification material, Co<3+> in the hole transmission layer can be prevented from diffusing towards the perovskite, so that the decomposition of the perovskite by Co<3+> is prevented, the defect mode is reduced, reverse recombination of charges is prevented, and the charge injection efficiency is improved; and moreover, the material is low in cost, the operation method is simple and is easy to control, and a new idea is provided for research ofinterface behavior of the perovskite solar cell.

Description

technical field [0001] The invention belongs to the field of perovskite solar cells, and relates to a FK102 ligand-modified perovskite solar cell and a method for preparing the perovskite layer. Background technique [0002] With the development of the world economy and the rapid growth of the population, energy, population, environment, etc. will increasingly become major problems to be solved by mankind in the next 50 years. At present, energy consumption mainly comes from fossil fuels (coal, oil, natural gas). Due to the limited reserves of fossil fuels and the environmental pollution caused by them, people began to turn their attention to renewable energy. Solar energy is the green renewable energy with the largest amount of resources and the most widely distributed. [0003] Solar cells can directly convert light energy into electrical energy, and the development of solar cells is one of the most effective ways to utilize solar energy. The solar battery is small in si...
