Description

Technical Field

[0001] The utility model belongs to the technical field of annealing furnaces, and in particular relates to a laminated annealing furnace. Background Art

[0002] Perovskite solar cells generally use a one-step or two-step process. The one-step process requires three steps: coating-VCD-annealing, and the two-step process requires a coating-annealing step. Both processes require annealing equipment.

[0003] Since the substrate of perovskite solar cells is flat, the annealing furnace is also flat in shape to adapt to the substrate of perovskite solar cells.

At the same time, a flat annealing furnace can only be equipped with one transmission line, and the production efficiency is not high.
