Abstract

The invention discloses a perovskite solar cell modified by FK102 ligand and a preparation method of the perovskite layer. The perovskite solar cell includes an electron transport layer, a perovskite, a hole transport layer and electrodes. The material constituting the modification layer is selected from FK102 ligands. This type of interface modification material can suppress the Co in the hole transport layer 3+ Diffusion to perovskite, thereby eliminating the Co 3+ The decomposition of perovskite reduces defect states, prevents charge reverse recombination, increases charge injection efficiency, and the material is cheap, easy to operate, and easy to control, providing a new method for the study of the interface behavior of perovskite solar cells. train of thought.

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...
