In actual production, it can also be configured according to the annealing process parameters. This invention uses mid-wave infrared radiation of 3000-5000nm to facilitate the annealing treatment of perovskite thin films. This allows for targeted energy utilization to achieve annealing and can achieve energy saving.

[0021] The frame 1 includes a side plate 4 and a support frame 5, which cooperate to form the receiving groove 11. The infrared heating lamp 2 is mounted on the support frame 5 and is detachably connected to it.
