Description

Technical Field

[0001] The utility model relates to the technical field of glove boxes, in particular to a perovskite solar cell glove box including a gas homogenizing component. Background Art

[0002] In recent years, perovskite solar cells have received great attention due to their excellent optoelectronic properties, high photoelectric conversion efficiency, and low cost, and their development speed has been rapidly improved. The main method for preparing perovskite solar cells is to spin-coat a pre-prepared perovskite solution, and the solvent of this solution is usually dimethyl sulfoxide (DMSO) and N,N-dimethylformamide (DMF).

[0003] The perovskite spin-coating process has strict requirements for environmental temperature, oxygen content, and humidity, and needs to be operated in a glove box. The temperature in the glove box is most suitable at 18-25 degrees Celsius. After exceeding 25 °C, the perovskite solution volatilizes quickly, forming many seed crystals, which in turn leads to poor spin-coating quality and further affects the battery efficiency.

[0004] In a traditional glove box, the cooling system is placed outside the operating box of the glove box, and the temperature is reduced through the circulation of the glove box and the cooling box. There are air exhaust ports and air suction ports in the operating box, and their diameters limit the cooling speed. Generally, it takes 30 minutes to cool down from 30 degrees to 20 degrees. Moreover, the heat generated by the annealing furnace working inside the traditional glove box will increase the temperature value inside the entire glove box by 31 °C.

[0005] Therefore, the existing glove box cannot ensure that the temperature inside the glove box is suitable for the temperature required by the perovskite spin-coating process during operation. Moreover, due to the influence of air flow disturbance, the perovskite solution volatilizes quickly, forming many seed crystals, which in turn leads to poor spin-coating quality and further affects the battery efficiency. Content of the Utility Model

[0006] The purpose of the utility model is to provide a perovskite solar cell glove box including a gas homogenizing component, so as to solve the problem that the existing glove box cannot ensure that the temperature inside the glove box is suitable for the temperature required by the perovskite spin-coating process during operation. Moreover, due to the influence of air flow disturbance, the perovskite solution volatilizes quickly, forming many seed crystals, which in turn leads to poor spin-coating quality and further affects the battery efficiency.

[0007] In the first aspect, the utility model provides a perovskite solar cell glove box including a gas homogenizing component, comprising:

[0008] A glove box body, and a fan assembly and a cold trap arranged inside the glove box body;

[0009] The cold trap includes parallelly arranged condensation fins and the gas homogenizing component arranged around the condensation fins;

[0010] The fan assembly is disposed above the condensation fins, and the air outlet direction of the fan assembly is parallel to or intersects with the arrangement direction of the condensation fins.

[0011] When the perovskite solar cell glove box is in a working state, during the process that the fan assembly and the cold trap cooperate to control the preset gaseous refrigerant to flow through the cold trap, the air distribution component is used to divert the air flow that has been cooled by the cold trap, reduce the air flow disturbance, and control the temperature of the perovskite solar cell glove box.

[0012] When the above technical solution is adopted, the glove box provided by the embodiment of the present invention includes: a glove box body, and a fan assembly and a cold trap disposed in the glove box body; the cold trap includes condensation fins arranged in parallel and an air distribution component disposed around the condensation fins; the fan assembly is disposed above the condensation fins, and the air outlet direction of the fan assembly is parallel to or intersects with the arrangement direction of the condensation fins; when the perovskite solar cell glove box is in a working state, during the process that the fan assembly and the cold trap cooperate to control the preset gaseous refrigerant to flow through the cold trap, the air distribution component is used to divert the air flow that has been cooled by the cold trap, reduce the air flow disturbance, and control the temperature of the perovskite solar cell glove box. Specifically, through the full contact between the condensation fins and the preset gaseous refrigerant, the temperature is quickly reduced to the temperature range required for the perovskite spin coating process. Through the air distribution component, the air flow disturbance meets the requirement of a relatively high air flow disturbance degree in the test bench area below the cold trap, reduces the influence of the air flow blown by the fan on the experimental quality, and completes the cooling of the perovskite solar cell glove box. Its cooling distribution is more uniform, meets the optimal ambient temperature range for perovskite battery processing. Further, it avoids the situation of many seed crystals caused by the fast volatilization of the perovskite solution due to too high temperature, optimizes the spin coating quality, and further improves the battery efficiency.

[0016] In some embodiments, the area of the second surface of the L - shaped air - distributing plate is larger than the projected area of the condensing fins on the second surface.

[0054] Figure 1 The figure shows a structural schematic diagram of a perovskite solar cell glove box including an air distribution assembly provided by an embodiment of the present invention. Refer to Figure 1 wherein the air distribution assembly 302 is a double-layer air distribution plate 302C.

Specifically, by fully contacting the condensation fins with the preset gaseous refrigerant, the temperature is quickly reduced to the temperature range required for the perovskite spin-coating process. Through the gas distribution assembly, the air flow disturbance meets the requirement of the test bench area below the cold trap for a higher degree of air flow disturbance, reduces the influence of the air flow blown by the fan on the experimental quality, and completes the cooling of the glove box for perovskite solar cells.
