[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] The present embodiment relates to a perovskite cell passivation device, which is useful for passivating the scribed grooves that need to be passivated in the perovskite cell chip after laser cutting on the substrate 10.

[0037] In terms of overall structure, the perovskite battery passivation device includes a housing 1 having a reaction chamber 100, a temperature adjustment unit, and a passivation gas generator. The housing 1 is provided with an opening connected to the reaction chamber 100, and a door body capable of blocking the opening; the temperature adjustment unit is provided on the housing 1, and is used to heat and / or cool the temperature in the reaction chamber 100. The passivation gas generator can be connected to the reaction chamber 100 to supply reaction gas into the reaction chamber 100.

[0038] The perovskite battery passivation device described in this embodiment, by providing a passivation gas generator connected to the reaction chamber 100, is conducive to the gas contacting with the substrate 10 of the perovskite battery to be processed in the reaction chamber 100, so that the passivation gas reacts with the scribed and exposed perovskite. The temperature adjustment unit is used to provide a suitable reaction temperature, which is conducive to improving the passivation efficiency, thereby helping to improve the passivation effect and performance of the perovskite battery.

[0039] Based on the above overall introduction, an exemplary structure of the perovskite battery passivation device described in this embodiment is as follows Figure 1 and Figure 2 As shown in .

[0040] When in use, the first control valve or the second control valve 201 can be selectively opened. Of course, it is also feasible to set only one of the carbon disulfide generator 5 and the ozone generator 2. Moreover, the passivation device in this embodiment can not only passivate the perovskite battery but also perform annealing treatment, which has good flexibility in use.

[0041] like Figure 1 As shown in the figure, the generating chamber of the carbon disulfide generator 5 in this embodiment is connected with the reaction chamber 100 through the air inlet pipe 7, and the generating chamber of the carbon disulfide generator 5 can be connected with the external air supply part, and the air flow out of the external air supply part can deliver the carbon disulfide gas in the generating chamber 100 into the reaction chamber 100.

As a preferred embodiment, a vent pipe 6 is provided between the external air supply unit and the generating chamber, and the seventh control valve 601 is provided on the vent pipe 6. In this embodiment, an evaporator 501 is provided in the generating chamber of the carbon disulfide generator 5, and the evaporator 501 is used to evaporate liquid carbon disulfide into gaseous carbon disulfide.

The provision of the heating wire 702 is conducive to ensuring that the carbon disulfide flowing into the reaction chamber 100 is gas, further improving the passivation efficiency. In the specific arrangement, the heating wire 702 can be arranged around the outer periphery of the air intake pipe 7, and of course, other arrangements can be used to arrange the heating wire 702 on the air intake pipe 7, as long as the use requirements are met.

[0045] The perovskite battery passivation device in this embodiment further includes a vacuum part 8 connected to the reaction chamber 100 through an exhaust pipe 9, the vacuum part 8 can extract the gas in the reaction chamber 100, and the exhaust pipe 9 is provided with a third control valve 904 for controlling the connection between the reaction chamber 100 and the vacuum part 8. The arrangement of the vacuum part 8 facilitates the extraction of the gas in the reaction chamber 100, thereby ensuring the passivation efficiency.

[0046] Specifically, before the perovskite battery passivation device is used, the gas in the reaction chamber 100 is discharged by opening the vacuum part 8 and the third control valve 904. Alternatively, after the passivation is completed, carbon disulfide or ozone can also be extracted from the reaction chamber 100 through the vacuum part 8, which can prevent the remaining gas from polluting the external environment on the one hand, and can be used to recycle the remaining gas on the other hand. The vacuum part 8 is specifically a vacuum pump.

A fifth control valve 903 can also be set between the cold trap part 901 and the liquid collecting part 902. When the gas in the exhaust pipe 9 is carbon disulfide, the fifth control valve 903 is in an open state.

[0048] As a preferred embodiment, Figure 2 As shown in , the housing 1 is provided with a temperature regulating chamber 200 separated from the reaction chamber 100, an air inlet and an air outlet for connecting the temperature regulating chamber 200 and the reaction chamber 100, and fans 3 are provided at the air inlet and the air outlet, and the fan 3 drives the gas to circulate between the temperature regulating chamber 200 and the reaction chamber 100, and the temperature regulating unit includes a heating part and / or a cooling part provided in the temperature regulating chamber 200.

[0050] Specifically, the temperature regulating chamber 200 is located above the reaction chamber 100, and the air inlet and the air outlet are spaced apart at both ends of the temperature regulating chamber 200. Of course, the positions of the temperature regulating chamber 200, the air inlet and the air outlet can also be adjusted according to the use requirements, and the solution that the fan 3 is only arranged at the air inlet or the air outlet is also feasible.

Preferably, the angle of the air guide plate can be adjusted. Here, the air guide plate 103 is provided to improve the flow uniformity of the airflow in the reaction chamber 100.

When the temperature in the reaction chamber 100 is higher than the target temperature, the controller controls the cooling unit to start cooling the gas, so that the temperature in the reaction chamber 100 is within a suitable range.

[0053] The housing 1 in this embodiment is preferably made of metal. As a preferred embodiment, a thermal insulation layer 104 is provided on the outer wall of the housing 1.

The substrate 10 is rectangular as a whole, and the two right-angled sides of the substrate 10 are respectively arranged corresponding to the first frame body 401 and the second frame body 402. Corresponding to the two right-angled sides at the bottom of each substrate 10, the above-mentioned slots are arranged in a plurality of intervals on the first frame body 401 and the second frame body 402. In other words, each right-angled side at the bottom of a substrate 10 is inserted into a plurality of slots of the corresponding frame, which is conducive to improving the insertion stability of the pole piece on the turnover trolley 4.

[0056] In the inserted state, two adjacent pole pieces are spaced apart, which is conducive to the reaction gas flowing through each substrate 10, thereby improving the passivation efficiency. Preferably, the portion of the substrate 10 that needs to be passivated is located outside the first frame 401 and the second frame 402, which is conducive to increasing the contact area with the passivation gas, thereby ensuring the passivation effect and efficiency.

[0057] In this embodiment, the first frame body 401 and the second frame body 402 can be made of a hard, high temperature resistant material such as PEEK (abbreviation for polyetheretherketone) or PTFE (abbreviation for polytetrafluoroethylene).
