Description

Technical Field

[0001] The utility model relates to the technical field of perovskite liquid film preparation, in particular to a perovskite constant temperature water bath device. Background Art

[0002] Perovskite is a new type of raw material component for solar cells. Its main components include but are not limited to MAIMAClMABrFAIPbI2PbCl2, etc. The solvents are mainly DMF, NMP, DMSO, DMPU, etc. in different proportions.

[0003] The existing perovskite solution production process is mostly to coat the perovskite solution with a slit coater, and after coating, a perovskite liquid film is formed on the substrate, and after drying, crystallization and annealing, a smooth and flat perovskite film layer is formed. During the entire production process, various measures are required to ensure that the perovskite solution is at a constant temperature within a specified range before coating, so as to keep the perovskite solution in a liquid state and avoid crystallization before coating due to temperature reduction, which affects the overall quality of the product. To this end, we propose a perovskite constant temperature water bath device. Utility Model Content
