Description

Technical Field

[0001] The utility model belongs to the field of perovskite batteries, and specifically relates to a perovskite battery protection device. Background Art

[0002] Perovskite solar cells are solar cells that use perovskite-type organic metal halide semiconductors as light-absorbing materials. They belong to the third generation of solar cells, also known as new concept solar cells. Perovskite cells need to face different weather conditions during use. Since perovskite cells need to be installed at a higher position and need to be installed in the open air, it is necessary to provide certain protection for the perovskite cells to increase the service life of the perovskite solar cells.

[0003] The Chinese patent with application number CN202221675925.2 discloses a perovskite battery protection device, which belongs to the field of perovskite battery technology, and includes a protective shell, and the front and back of the protective shell are provided with a plurality of fixers, and the upper surface of the fixer is provided with a first card slot, and the upper surfaces of the plurality of fixers are respectively fixedly connected with a plurality of fixing blocks through the first card slot. The perovskite battery protection device ensures the stability of the installation of the protective shell and the cover plate by providing a protective shell, a threaded hole and a cover plate, and the protective shell has a good protective function, thereby avoiding the occurrence of safety accidents, and the protective device can quickly dissipate heat through the cooperation of the radiator and the heat sink during use, thereby ensuring the photoelectric conversion efficiency of the perovskite battery, and the installation method of the protective device is simple and fast, so that it is convenient for the staff to replace and repair the perovskite battery in the protective device.

[0004] In the above-mentioned comparative document, the radiator is driven by a dual-axis motor in the installation box to discharge heat through the heat sink. However, in actual use, the heat generated by the perovskite battery needs to be transferred to the heat sink through the protective shell. The heat dissipation effect is poor, which can easily cause the perovskite battery to overheat. Moreover, when the hot air inside the heat sink flows outward, it will blow directly to the bottom of the installation box. Part of the hot air flowing outward will hit the placement surface at the bottom of the installation box and flow back into the installation box again, causing the hot air to form a heat cycle inside the installation box, resulting in poor heat dissipation, which greatly affects the service life of the perovskite battery.

[0005] In view of this, the present utility model is proposed. Summary of the invention
