Problems solved by technology

[0004] In the existing manufacturing technologies of modular perovskite solar cells, the continuity and uniformity of the large-area perovskite active layer produced by these technologies are not good, and there are often small holes in the active layer, which makes the module easy to The disadvantage of leakage, or the perovskite active layer is destroyed during the subsequent solar cell assembly process
These problems make the photoelectric conversion efficiency of the battery module not high, and are often accompanied by the generation of current hysteresis (the so-called current hysteresis refers to the I-V curves of the forward sweep and reverse sweep of the module do not overlap)

Abstract

The invention relates to a large-area perovskite film, a perovskite solar cell module and a manufacturing method. The manufacturing method of the large-area perovskite film comprises the steps of providing an initial solution to a conductive substrate so as to form a film material, wherein perovskite is represented by a general expression ABX3, and a solute of the initial solution at least comprises A, B and X; and applying an anti-solvent to the film material.

Description

technical field [0001] The invention relates to a perovskite film, a perovskite solar cell and a manufacturing method thereof, in particular to a large-area perovskite film, a perovskite solar cell module and a manufacturing method thereof. Background technique [0002] In recent years, with the continuous increase in energy consumption, and the extensive use of fossil energy has also caused global warming and climate change, causing many disasters. Finding alternative energy sources without sequelae has become one of the important issues for human beings today. Alternative energy sources that have received attention include: hydropower, wind power, tides, solar energy, and geothermal energy, etc. Among them, solar energy is the most anticipated, because solar energy has the advantages of low pollution, less environmental restrictions, and high safety. [0003] A perovskite solar cell is a photovoltaic module in which a perovskite film is used as the active layer (Active Lay...
