[0043] In the prior art, the stability test of perovskite battery is usually directly placed under the sunlight or the light source simulating sunlight for irradiation to test.The device structure for stability test is simple, and the test result can be affected by the environmental temperature and humidity, which cannot accurately reflect the single influence degree of light on perovskite battery, and the test personnel cannot accurately identify the key influencing factors in the test process.

[0044] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a kind of light test device for perovskite battery, can control single factor respectively to test, it is convenient for test personnel to accurately identify influencing factor, to provide research and development basis for the research and development of perovskite battery.

[0045] Please refer to Figure 1 andFigure 2 , Figure 1 A top view of an illumination testing apparatus for perovskite solar cells according to some embodiments of the present disclosure is shown. Figure 2 A cross-sectional view of a light-illuminated testing apparatus for perovskite solar cells provided according to some embodiments of the present disclosure is shown.

[0046] like Figure 1 and Figure 2 As shown, the illumination testing apparatus 100 for perovskite solar cells may include a sealed test box 110, inside which the perovskite solar cell 200 to be tested is placed. The sealed test box 110 may include a top cover 111 and a tank 112. A translucent quartz glass 120 is inlaid in the center of the panel of the top cover 111, allowing light to pass through the inlaid translucent quartz glass 120 and irradiate the perovskite solar cell 200 inside the sealed test box 110.

[0047] In some embodiments, the illumination testing apparatus 100 for perovskite solar cells may further include a light incident device 130 located above the top cover 111 to provide light illuminating the interior of the sealed test chamber 110. Preferably, the light incident device 130 can adjust the intensity, color, or frequency of the light.

[0048] The five sides of the tank 112 can be sealed together by welding. Furthermore, the tank 112 can be made of thin sheet metal made of stainless steel or heat-resistant metal.

[0049] In some embodiments, the top cover 111 and the groove 112 can be connected by a hinge 101. The hinge 101 allows the sealed test box 110 to be easily opened and closed to access the perovskite battery 200 inside the sealed test box 110.

[0050] A dovetail groove for embedding a sealing ring may be provided between the contact surfaces of the groove 112 and the top cover 111.

[0051] Please refer to Figure 3 , Figure 3 A partial schematic diagram of the contact surface of an illumination testing apparatus for perovskite solar cells provided according to some embodiments of the present disclosure is shown.

[0052] Figure 3 for Figure 2 An enlarged schematic diagram of a partial structural location A of the illumination testing apparatus 100 for perovskite solar cells in the illustrated embodiment. (See diagram below.) Figure 3 As shown, a dovetail groove 140 for embedding a sealing ring 102 can be formed on the groove 112 between the contact surfaces of the upper cover 111 and the groove 112. After the dovetail groove 140 of the groove 112 is fitted with the smooth surface of the upper cover 111, an effective seal can be achieved between the upper cover 111 and the groove 112.

[0053] In some embodiments, the dovetail groove 140 can be machined by a 60° milling cutter, and preferably, the depth of the dovetail groove 140 is 4.5 mm. The sealing ring 102 can be a rubber sealing ring. Preferably, the sealing ring 102 can be a circular sealing ring with a diameter of Φ5 mm.

[0054] By using the dovetail groove 140, a closed loop for embedding a sealing ring, provided between the contact surfaces of the groove 112 and the top cover 111, the sealing test box 110 can be effectively sealed, and the sealing performance is further improved.

[0055] like Figure 2 As shown, the illumination testing apparatus 100 for perovskite solar cells may further include a testing hot stage 150. The testing hot stage 150 can be centrally placed within the sealed test chamber 110 for holding the perovskite solar cell 200. The temperature of the testing hot stage 150 can be set and adjusted according to actual conditions to test the heat resistance of the perovskite solar cell 200. In some embodiments, the testing hot stage 150 may also be maintained at a set temperature to ensure that the temperature factor remains constant during the testing process.

[0056] The testing hot stage 150 can be connected to a power source to achieve heating and temperature rise by energizing it. In some embodiments, the power source is an external power source, such as... Figure 1 As shown, the sealed test box 110 may be provided with a sealed test hot stage power supply outlet 151. Through the test hot stage power supply outlet 151, the test hot stage 150 can be easily connected to an external power source to enable the test hot stage to be powered on.

[0058] The air inlet 161 can be located near the top cover 111 of the sealed test box 110 to better allow gas to enter and distribute the gas more quickly above the perovskite solar cell 200. The air outlet 162 can be located at the bottom of the sealed test box 110 to better expel gas.

[0059] The gas can be a protective gas and / or a test medium. Preferably, the test medium can include a high-oxygen gas with oxygen levels exceeding a set threshold or a high-humidity gas with humidity levels exceeding a set threshold.

[0060] By adjusting and controlling the test medium, the influence of different media on the perovskite battery 200 can be tested. For example, by adjusting the oxygen content in the gas, the influence of oxygen on the perovskite battery 200 can be tested. For another example, by adjusting the humidity of the high humidity gas, the influence of humidity on the perovskite battery 200 can be tested.

[0061] The protective gas can be nitrogen or other inert gas. When the perovskite battery 200 is tested for temperature or light, the protective gas can be introduced into the sealed test box 110 to avoid the test medium affecting the test results of the perovskite battery 200.

[0062] Preferably, the gas inlet 161 can further include a pressure gauge and a gas inlet control valve. By adding the pressure gauge and the gas inlet control valve, the light test device for the perovskite battery 100 can further adjust the pressure inside the sealed test box 110 and control the pressure to be stable.

[0063] In summary, the light test device for the perovskite battery provided by the present disclosure can accurately find the factors affecting the perovskite battery by testing, and can control individual factors to test the perovskite battery, which facilitates the test personnel to accurately identify the influencing factors and provides research basis for the research and development of the perovskite battery.
