Embodiment 1

[0045] 1. FTO (30*60cm) glass is scribed P1 by laser (1024 red light), the line spacing is 1cm, and then the hole transport layer is prepared by magnetron sputtering in the hole transport layer preparation chamber 4. The material of the hole transport layer is nickel oxide, and the preparation method is sputtering, scraping or spraying, or inkjet printing, and the thickness of the prepared nickel oxide is 70-80nm.

[0046] 2. After that, the sample enters the sampling chamber 1, and the sampling chamber 1 and the first evaporation chamber 2 are simultaneously evacuated to 1E-7torr, and the first transfer door 6 between the sampling chamber 1 and the first evaporation chamber 2 is opened. The sample enters the first evaporation chamber 2, the first transfer door 6 is closed, and the baffle (not shown) on the substrate is closed.

[0047] 3. Put lead iodide or lead chloride powder in the sublimation tank 22, vacuumize, heat to 310 degrees, wait for the lead iodide or lead chlori...

Abstract

The invention provides a manufacturing method of a large-area perovskite solar cell. The method comprises the steps of making a line on FTO glasses by laser, preparing a cavity transmission layer, preparing lead iodide or lead chloride in a first evaporating chamber, preparing methyl amine iodine in a second evaporating chamber, forming a perovskite film through reaction, preparing an electronic transmission layer by a spray method, making a line P2 by laser, preparing a metal electrode, and making a line P3 by laser to form a large-area perovskite component. The invention also provides a manufacturing system of a large-area perovskite solar cell. The system comprises a sample introduction chamber, the first evaporating chamber, the second evaporating chamber, a cavity transmission layer preparation room, and a metal electrode preparation room. The large-area uniformity and preparation rate of the perovskite solar cell can be greatly improved.

Description

【Technical field】 [0001] The invention relates to the technical field of solar cells, in particular to a method and system for preparing large-area perovskite solar cells. 【Background technique】 [0002] Perovskite solar cells are developing very rapidly. Since the first solid-state perovskite solar cells were prepared in 2012, the efficiency has been 9.7%, and the efficiency has risen very fast. So far, the efficiency of small-area perovskite solar cells has reached 21%. , but these high-efficiency batteries are all prepared by spin-coating method, which does not have the potential for large-scale industrialization. In 2014, Oxford University developed a thermal evaporation method to prepare perovskite solar cells with an efficiency of 15%. This method is suitable for industrialization, but there are still problems with large-area uniformity. [0003] Therefore, it is necessary to provide an improved technical solution to overcome the above problems. 【Content of inventio...
