Problems solved by technology

During the working process, the substrate substrate faces down, and it is coated from bottom to top, and other equipment components are added to supply and recover the solution; the coating method is that the substrate moves continuously, and the wire rod rotates to transfer the solution to it; it is mainly applicable Because the liquid film is thin and has a certain viscosity, it is not suitable for coating on glass and other flat substrates, and it is not suitable for coating from top to bottom

Abstract

The invention discloses a scrape coating device applied to preparation of provskite batteries and a thin film preparation method. The scrape coating device applied to preparation of the perovskite batteries comprises a bar which comprises a bar body; a liquid storage cavity extending axially is arranged in the bar body and used for storing feed liquid; the bar body is provided with a slit extending axially in the surface and communicated with the liquid storage cavity. According to the embodiment, the scrape coating device is adaptable to preparation of large-area thin film or laminated structures; the bar of the scrape coating device can keep continuous and enough liquid feed quantity in long-distance scrape coating process and keep coated products uniform; the scrape coating device is good for coating of low-viscosity solution on large-size substrates.

Description

technical field [0001] The invention particularly relates to a scraping equipment and a method for preparing a thin film applied to the preparation of a perovskite battery, belonging to the technical field of perovskite thin film battery processing. Background technique [0002] As an emerging third-generation solar cell, perovskite solar cells have seen their efficiency increase year by year since 2009, with an effective area of ​​0.09cm 2 The efficiency of perovskite cells has exceeded 23%, and its wide range of raw materials, low cost, and simple preparation have attracted many researchers and investors. However, there are still many difficulties to be overcome in order to achieve large-scale production. In addition to the preparation quality of the perovskite thin film, the preparation of the hole transport layer and electron transport layer on both sides is also a topic that needs to be optimized. Such as NiO, SnO, Cu 2 O, ZnO, TiO, PCBM, C60, Spiro and other materia...
