[0032] In the heat plate annealing process of prior art, the heat plate is exposed to the atmosphere, and the target part on the heat plate is also exposed to the atmosphere, when annealing, the dust and other particulate matters in the environment can fall on the target part, which affects the quality of perovskite layer formed. In the present application, the target part can be placed in the containing space 11, and the containing space 11 can be separated from the outside under the action of the wall body, so as to reduce or avoid the influence of dust and other particulate matters in the external environment on the target part during annealing, and improve the quality of perovskite layer formed.
[0033] Referring to Figure 1 For the movement of annealing device, the bottom of frame body 1 is provided with universal wheel 12, and the annealing device is in contact with the ground through universal wheel 12 to facilitate the movement of the annealing device. Among them, universal wheel 12 can be provided with multiple, and universal wheel 12 can be arranged at the edge position of the bottom of frame body 1. In the embodiment, universal wheel 12 can be provided with four, and four universal wheels 12 are distributed at the four corners of frame body 1.
[0034] Referring to Figure 2The radiation lamp 32 is arranged in the accommodating space 11, and the radiation lamp 32 can be installed on the frame body 1 through the radiation mounting frame 3. Specifically, the radiation mounting frame 3 is arranged in the accommodating space 11 and fixedly installed on the frame body 1, and the radiation lamp 32 is fixedly installed on one side of the radiation mounting frame 3 facing the target component, specifically, the lower side of the radiation mounting frame 3. The radiation lamp 32 is used to generate radiation light rays irradiating towards the target component, and the target component absorbs the energy of the radiation light rays so that the target component can be annealed. Specifically, the radiation lamp 32 can be an infrared lamp, and the radiation light rays generated by the radiation lamp 32 can be infrared light rays, which irradiate to the perovskite film of the target component to heat the perovskite film, thereby realizing the annealing treatment of the perovskite film.

The number of thermocouples TC331 can be set to five or nine, with five or nine thermocouples TC331 monitoring the temperature at the center and around the target component. Each thermocouple TC331 can be set to both monitoring and control modes; that is, each thermocouple TC331 can function as either a control TC or a monitoring TC.
