vacuum spray pyrolysis coater for perovskite thin film

vacuum spray pyrolysis film formation method is to spray the solution on a heated base after atomizing the solution, and then obtain the desired material structure on the substrate. This material preparation method is particularly suitable for depositing oxides, and has a long history in the application of preparing transparent electrodes. This method is now widely used in the preparation of perovskite solar cells. This equipment adds a multi-nozzle coordination system and a vacuum system on the basis of ordinary pyrolysis spraying. It is equipped with three high-pressure gas-driven atomizing nozzles and matching anti-dripping baffles. It can work together through the touch screen to make Multi-layer film. The vacuum system can provide a basic vacuum of 5000Pa, and can be sprayed and pyrolyzed under a protective gas environment after being filled with an inert gas. In addition, the instrument also has a high-precision peristaltic pump and a precision-programmed stepping motor moving mechanism. At the same time, the substrate temperature can also be controlled to meet your various test needs.
