Problems solved by technology

Conventional blade coating and slit coating methods for preparing perovskite include two methods: high-temperature hot stage preparation and nitrogen blowing assisted film formation. The advantage of the two methods is that they are highly integrated and suitable for the needs of production lines. The platform method has restrictions on the production of flexible substrates, and its preparation temperature is usually above 140°C. Cheap low-melting point polymers such as PET will not be used. The method of nitrogen blowing assisted film formation is suitable for low-temperature preparation, but due to continuous blowing, It is more difficult to realize production in the glove box

Abstract

The invention relates to the technical field of solar cell production, in particular to a perovskite film preparation device which comprises a perovskite film coating adjusting device, an anti-solvent film coating adjusting device and a substrate transmission mechanism, wherein the perovskite film coating adjusting device and the anti-solvent film coating adjusting device are both arranged above the substrate transmission mechanism. The perovskite coating film adjusting device comprises a first adjusting vehicle, a first flow control valve and a perovskite coating film element, wherein the perovskite coating film element is arranged on the first adjusting vehicle in a lifting mode, and the flow is controlled through the first flow control valve; and the anti-solvent coating film adjusting device comprises a second adjusting vehicle, a second flow control valve and an anti-solvent coating film element, wherein the anti-solvent coating element is arranged on the second adjusting vehicle in a lifting mode, and the flow is controlled through the second flow control valve. According to the invention, the perovskite thin film is prepared by directly adopting an anti-solvent post-treatment method after blade coating of the wet film, so that the large-area, uniform and pinhole-free perovskite thin film can be prepared at low temperature.

Description

Technical field [0001] The present invention relates to the field of solar cell preparation, and in particular to a perovskite film preparation device. Background technique [0002] In recent years, the perovskite battery has been greatly concerned due to the preparation cost, high efficiency, band gap adjustable, and the high advantages of absorption coefficients have been greatly concerned. In just a few years, photoelectric conversion efficiency increased from 3.8% to 23.7%. While researching hotspots in the field of photovoltaic devices, the perovskite battery also attracted many companies to achieve the industrialization of the perovskite battery. [0003] At present, there is a difficulty of stability and large area preparation techniques. In the prior art, laboratory is highly efficient techniques typically adopt a spin coating method, but the method cannot meet the needs of industrialization. In order to further improve the efficiency of industrialization and reduce costs...
