[0033] In embodiments of the present disclosure, the frame of the photovoltaic module includes a full-screen frame and a non-full-screen frame.

[0034] In some embodiments, the perovskite cell 2 may be disposed on a non-full screen frame.

[0035] Accordingly, in some embodiments, Figure 1 As shown, the top plate 13 extends horizontally from the top end of the side plate 12 and bends downward at one end away from the side plate 12 , forming a glue overflow groove 131 on the side of the top plate 12 facing the support plate 11 ; the perovskite cell 2 is arranged on the surface of the top plate 13 opposite to the glue overflow groove 131 .

[0036] In some embodiments, the perovskite cell 2 may be disposed on a full-screen frame. The top of the full-screen frame top plate 13 is not higher than the upper surface of the laminate assembly.

[0037] Accordingly, in some embodiments, Figure 2 As shown, the top plate 13 extends horizontally from the top end of the side plate 12 and bends downward at one end away from the side plate 12, and the side plate 12 and the top plate 13 enclose a glue overflow groove 121; the end surface of the top plate 13 away from the side plate 12 is used to abut the laminated assembly; the side of the top plate 13 away from the support plate 11 is a plane, and the perovskite cell 2 is arranged on the plane on the side of the top plate 13 away from the support plate 11.

[0039] Second, as Figure 3 , Figure 4 As shown, the embodiment of the present disclosure provides a photovoltaic component, including: a photovoltaic component frame 1, the photovoltaic component frame 1 is the photovoltaic component frame described in the first aspect of the embodiment of the present disclosure; a laminated component, the laminated component includes a solar cell component 31, and a metal pipe 32 laid on the back of the solar cell component 31; the photovoltaic component also includes a circulation pump 4 and a heat dissipation component 5; the metal pipe 32 and the circulation pump 4 are connected through a connecting pipe to form a circulation pipeline; the circulation pump 4 drives the circulation medium to circulate in the circulation pipeline; the heat dissipation component 5 is coupled to a part of the connecting pipe, and is used to cool the circulation medium in the circulation pipeline; the perovskite cell 2 arranged on the photovoltaic component frame 1 is electrically connected to the circulation pump 4 and the heat dissipation component 5, respectively, and is used to supply power to the circulation pump 4 and the heat dissipation component 5.

[0040] In the embodiments of the present disclosure, a metal pipe 32 is laid on the back of the solar cell module 31, which has fast heat dissipation, can effectively absorb the heat of the solar cell module 31 and export it to the heat dissipation component 5 through the circulation pipeline in the circulation pipeline, and then the heat dissipation component 5 releases the heat, which can improve the heat dissipation effect of the solar cell module 31, increase the temperature reduction range of the module, thereby effectively suppressing the increase in the working temperature of the photovoltaic module, reducing the power loss of the module, and also being beneficial to using high-efficiency single-crystal battery modules to increase the output current of the photovoltaic cell; in the embodiments of the present disclosure, the perovskite battery 2 is used to supply power to the circulation pump 4 and the heat dissipation component 5, without an external power supply, which is beneficial to simplifying the structure of the photovoltaic module and reducing costs.

[0041] The embodiments of the present disclosure do not make special limitations on the material of the metal pipe 32. For example, the metal pipe can be made of metal materials with good thermal conductivity such as aluminum, copper, zinc, etc.

[0042] In some embodiments, the output power of the perovskite battery 2 is not less than the sum of the rated power of the circulation pump 4 and the rated power of the heat dissipation component 5.

[0043] For example, the rated power of the heat dissipation component 5 is 10W - 20W, the rated power of the circulation pump 4 is 5W - 10W, and the output power of the perovskite battery 2 is 40W, which meets the requirement of supplying power to both the heat dissipation component 5 and the circulation pump 4 at the same time. In the embodiments of the present disclosure, the perovskite battery 2 supplies power to the heat dissipation component 5 and the circulation pump 4 at the same time, which is beneficial to realizing the simultaneous start and stop of the perovskite battery 2, the heat dissipation component 5, the circulation pump 4 and the solar cell module 31, ensuring that the perovskite battery 2 is also in the working state when the solar cell module 31 is working, supplying power to the circulation pump 4 and the heat dissipation component 5, so as to effectively dissipate heat and cool down the working solar cell module 31.

[0044] The embodiments of the present disclosure do not make special limitations on the circulating medium.

[0045] In some embodiments, the circulating medium includes any one of ethylene glycol, calcium chloride, methanol, ethanol, and glycerol.

[0046] Ethylene glycol, calcium chloride, methanol, ethanol, and glycerol have good thermal conductivity, can effectively export the heat of the photovoltaic module, and improve the heat dissipation effect of the photovoltaic module.

[0047] The embodiments of the present disclosure do not make special limitations on the heat dissipation component 5.

[0048] In some embodiments, the heat dissipation component 5 includes a semiconductor heat dissipation component; the semiconductor heat dissipation component is wrapped outside the connecting pipe.

[0049] Figure 5 It is a schematic diagram of the principle of semiconductor heat dissipation.

[0050] As Figure 5 shown, the semiconductor heat dissipation component converts electrical energy into refrigeration heat through the thermoelectric effect. The working principle is that under the drive of the material current and temperature difference, an intrinsic potential difference is generated between two differently doped semiconductor materials (i.e., P-type and N-type materials), thereby generating a cold and heat effect; by changing the applied current, the temperature inside the semiconductor heat dissipation component can be controlled.

[0051] In some embodiments, the semiconductor heat dissipation component is a semiconductor heat sink, which can be conveniently wrapped outside the connecting pipe.

[0052] In some embodiments, the heat dissipation component 5 includes an air-cooled heat dissipation component.

[0053] In some embodiments, as Figure 3 shown, the lamination component further includes an aluminum foil 33, which covers the side of the metal pipe 32 facing away from the solar cell component 31.

[0054] In the embodiments of the present disclosure, covering the aluminum foil 33 on the side of the metal pipe 32 facing away from the solar cell component 31 can reflect the thermal radiation in the environment, avoid the circulating medium in the metal pipe 32 from heating up with the increase of the ambient temperature, so that the circulating medium in the metal pipe 32 mainly heats up due to the increase of the temperature of the solar cell component 31, and improve the heat dissipation effect on the solar cell component 31.

[0055] In some embodiments, the aluminum foil 33 is a self-adhesive aluminum foil.

[0056] In some embodiments, as Figure 3 shown, the lamination component further includes a thermal insulation layer 34, which covers the side of the aluminum foil 33 facing away from the metal pipe 32.

[0057] In the embodiments of the present disclosure, covering the thermal insulation layer 34 can isolate the temperature of the metal pipe 32 from the ambient temperature, avoid the circulating medium in the metal pipe 32 from heating up with the increase of the ambient temperature, so that the circulating medium in the metal pipe 32 mainly heats up due to the increase of the temperature of the solar cell component 31, and improve the heat dissipation effect on the solar cell component 31.

[0058] The embodiments of the present disclosure do not make special limitations on the shape of the metal pipe 32.

[0059] In some embodiments, the metal pipe 32 is laid in a "bow" shape or a "Z" shape on the back of the solar cell component 31.

[0060] In some embodiments, as Figure 3As shown, the metal pipe 32 includes two main pipes arranged in parallel, and a branch pipe between the two main pipes for connecting the two main pipes. The two main pipes are respectively connected to the liquid inlet and outlet of the metal pipe 32, and are further connected to both ends of the circulation pump 4 through connecting pipes.

[0061] In some embodiments, the metal pipe 32 is a heat dissipation pipe with a double - helix structure. The liquid inlet and outlet of the metal pipe 32 are arranged at the first end of the photovoltaic module; the metal pipe 32 includes a first pipe and a second pipe. The first pipe is communicated with the liquid inlet at the first end, and the second pipe is communicated with the liquid outlet at the first end; the first pipe and the second pipe are communicated at the second end of the photovoltaic module; the first pipe and the second pipe are alternately arranged on the back of the solar cell module 31.

[0062] When the circulation pump 4 works, it drives the circulating medium to enter the first pipe from the liquid inlet and flow along the first pipe to the second end; then the circulating medium enters the second pipe at the second end and flows along the second pipe to the second end and flows out from the liquid outlet; the flow directions of the circulating medium in the first pipe and the second pipe are opposite, and the temperature of the circulating medium in the first pipe is lower than that in the second pipe, forming a circulating pipeline structure in the form of a double - helix. The cold and hot pipes are alternately arranged, and the flow directions of the circulating medium therein are opposite, so that there is always a large temperature difference in the circulating medium, which is beneficial to improving the cooling efficiency.

[0063] In order to enable those skilled in the art to more clearly understand the technical solutions provided by the embodiments of the present disclosure, the technical solutions provided by the embodiments of the present disclosure will be described in detail through specific embodiments as follows:

[0064] Embodiment

[0065] This embodiment provides a photovoltaic module, as Figure 3 , Figure 4 shown, including: a photovoltaic module frame, which includes: a metal frame, including a horizontally arranged support plate 11, a side plate 12 vertically arranged at one end of the support plate 11, and a top plate 13 extending from the top of the side plate 12. The support plate 11, the side plate 12, and the top plate 13 enclose an installation groove for installing a lamination assembly; a perovskite battery 2 is arranged on the surface of the top plate 13 facing away from the support plate 11; a lamination assembly, the lamination assembly includes a solar cell module 31, a metal pipe 32 laid on the back of the solar cell module 31; the photovoltaic module further includes a circulation pump 4 and a heat dissipation assembly 5; the metal pipe 32 and the circulation pump 4 are communicated through a connecting pipe to form a circulation pipeline; the circulation pump 4 drives the circulating medium to circulate in the circulation pipeline; the heat dissipation assembly 5 is coupled to a part of the connecting pipe for cooling the circulating medium in the circulation pipeline; the perovskite batteries 2 arranged on the photovoltaic module frame 1 are respectively electrically connected to the circulation pump 4 and the heat dissipation assembly 5 for supplying power to the circulation pump 4 and the heat dissipation assembly 5.

[0066] The metal pipe 32 can be an aluminum pipe, a copper pipe, a zinc pipe, etc., and has good thermal conductivity.

[0067] The heat dissipation component 5 is a semiconductor heat sink, and the semiconductor heat sink is wrapped around the connecting pipe.

[0068] The rated power of the semiconductor heat dissipation component is 10W - 20W, the rated power of the circulation pump 4 is 5W - 10W, and the power of the perovskite battery 2 is 40W, which meets the demand for simultaneously powering the heat dissipation component 5 and the circulation pump 4 without an external power supply.

[0069] The circulating medium is one of ethylene glycol, calcium chloride, methanol, ethanol, and glycerol.

[0070] The lamination component further includes an aluminum foil 33, which covers the side of the metal pipe 32 facing away from the solar cell component 31; the aluminum foil 33 is an aluminum foil with self-adhesive; the thermal insulation layer 34 covers the side of the aluminum foil 33 facing away from the metal pipe 32.

[0071] Comparative example

[0072] The photovoltaic component in the comparative example is a conventional photovoltaic component, and does not have a heat dissipation system composed of a metal pipe, a circulation pump, a heat dissipation component, a photovoltaic sample, and a circulating medium.

[0073] The working temperature of the photovoltaic component was measured at 3 different time periods in a day. Among them, the ambient temperatures in time period 1, time period 2, and time period 3 increased in sequence. The measured results are shown in Table 1.

[0074] Table 1

[0075] Operating temperature of the photovoltaic module Embodiment Comparative example Period 1 28.1℃ 32.5℃ Period 2 39.3℃ 45.5℃ Period 3 50.6℃ 58.6℃

[0076] As can be seen from Table 1, the working temperature of the photovoltaic component in the example is significantly lower than that of the conventional photovoltaic component in time period 1, time period 2, and time period 3. The heat dissipation system composed of a metal pipe, a circulation pump, a heat dissipation component, a photovoltaic sample, and a circulating medium in the example increases the temperature reduction amplitude of the photovoltaic component, effectively inhibits the increase of the working temperature of the photovoltaic component, and thus can reduce the power loss of the component.
