[0049] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0053] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0054] The term "multiple" in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0055] Photovoltaic modules, as components for photoelectric conversion, are typically installed outdoors in open, well-lit areas. Due to the fluctuating weather conditions, the environment in which these modules are located also varies greatly. On rainy days, rainwater inevitably falls on the solar cells of these modules. Solar cells often contain pollutants such as lead, which are known to pose significant environmental risks. If these pollutants leak and are washed away by rainwater into the environment, they will inevitably cause some environmental pollution.

[0056] In view of this, firstly, Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present application provides a photovoltaic assembly 1, which includes a frame 10, a solar cell 20, and a pollutant treatment component 30. The solar cell 20 is mounted on the frame 10, and the pollutant treatment component 30 is mounted on the frame 10. The pollutant treatment component 30 includes a flow guide module 31 and an adsorption module 32. The flow guide module 31 is used to guide fluid to the adsorption module 32, and the adsorption module 32 is used to adsorb pollutants.

[0057] Optionally, the solar cell 20 may be a perovskite solar cell or a silicon solar cell.

[0058] The solar cell 20 is arranged on the frame 10 , and the frame 10 can provide certain support and protection for the solar cell 20 . When the angle of the solar cell 20 needs to be adjusted, the angle of the solar cell 20 can be adjusted by rotating the frame 10 .

[0059] It is understandable that the solar cell 20 usually contains heavy metals such as lead. After the lead and other heavy metals in the solar cell 20 leak out, they will adhere to the surface of the solar cell 20. Under the erosion of rainwater, the lead and other heavy metals attached to the surface of the solar cell 20 will flow to the frame 10 with the rainwater.

[0060] Since the pollution treatment component 30 is disposed on the frame 10 and includes the diversion module 31 , rainwater on the solar cell 20 will flow toward the diversion module 31 and, under the guidance of the diversion module 31 , flow to the adsorption module 32 .

[0061] Specifically, the pollutant treatment component 30 can be set on the lowermost frame of the frame 10 after installation according to the posture of the photovoltaic module 1 after installation, or one or more pollutant treatment components 30 can be set on multiple frames of the frame 10 as needed.

[0062] Optionally, the adsorption module 32 may include a lead ion adsorbent or other substance for adsorbing pollutants such as heavy metals.

[0063] The adsorption module 32 may also include a porous adsorption material having a rich pore structure, which can adsorb water-soluble lead ions by physical adsorption or chemical adsorption, thereby reducing the risk of lead ions in the solar cell 20 leaking into the environment with rainwater.

[0064] Optionally, the porous adsorbent material includes at least one of montmorillonite, activated carbon, diatomaceous earth, zeolite, molecular sieve, kaolin, metal organic frameworks (MOFs), and covalent organic frameworks (COFs). The porous adsorbent material may be loaded with phosphate. Phosphate ions can coordinate with lead ions, thereby further enhancing the adsorption capacity of the porous adsorbent material for lead. Furthermore, the porous adsorbent material is saturated with phosphate.

[0065] Of course, the adsorption module 32 may also include other compounds capable of absorbing pollutants, and the specific configuration may be based on actual needs.

[0066] Therefore, the harmful substances leaked from the solar cell 20 flow toward the frame 10 under the scouring of rainwater, and flow toward the adsorption module 32 under the guidance of the diversion module 31, and are finally adsorbed by the adsorption module 32. This helps to reduce the risk of harmful substances leaked from the solar cell 20 being lost to the environment.

[0067] Optionally, the photovoltaic assembly 1 may include a plurality of pollutant treatment components 30, and the plurality of pollutant treatment components 30 may be arranged at intervals along the circumference of the frame 10, so that when rainwater on the solar cell 20 flows to multiple locations of the frame 10, the corresponding pollutant treatment components 30 guide the rainwater to the adsorption module 32 through their own diversion modules 31 and are absorbed by the adsorption module 32.

[0068] The photovoltaic module 1 provided in the embodiment of the present application is configured such that a pollutant treatment component 30 is disposed on the frame 10, and the pollutant treatment component 30 includes a diversion module 31 and an adsorption module 32, so that rainwater on the solar cell 20 is guided to the adsorption module 32 through the diversion module 31, and pollutants such as lead in the rainwater are adsorbed through the adsorption module 32. This is beneficial to reducing the risk of pollutants such as lead leaking from the solar cell 20 and leaking into the environment, and is beneficial to reducing the pollution to the environment caused by the photovoltaic module 1 during use.

[0069] In some embodiments, the adsorption module 32 includes a lead ion adsorbent.

[0070] Once the solar cell 20 leaks, the leakage is large and the lead ions are the most serious environmental pollutants. Therefore, the adsorption module 32 includes a lead ion adsorbent, which can absorb the lead ions leaked from the solar cell 20, which is beneficial to reducing the pollution of the lead ions leaked from the solar cell 20 to the environment.

[0071] In some embodiments, the lead ion adsorbent includes at least one of montmorillonite, activated carbon, diatomaceous earth, zeolite, molecular sieve, kaolin, metal organic framework 10 materials, and covalent organic framework materials.

[0072] Montmorillonite, activated carbon, diatomaceous earth, zeolite, molecular sieve, kaolin, metal organic framework 10 materials and covalent organic framework materials are relatively cheap, easy to obtain, and have good adsorption effects on lead ions, etc. This is beneficial for improving the adsorption effect of the adsorption module 32 on lead ions while also reducing the manufacturing cost of the photovoltaic component 1.

[0073] In some embodiments, as Figure 2 and Figure 3 As shown, the pollutant treatment component 30 further includes a monitoring module 33 . The monitoring module 33 is disposed between the flow guide module 31 and the adsorption module 32 and is used to monitor pollutants.

[0074] Optionally, the monitoring module 33 may include a sensor or a test paper.

[0075] The monitoring module 33 is arranged between the diversion module 31 and the adsorption module 32. The rainwater first flows to the monitoring module 33 under the guidance of the diversion module 31. When the monitoring module 33 detects pollutants such as lead ions, it can produce some color changes or generate electrical signals to transmit to the control system, so that the operator can promptly discover the leakage of harmful substances such as lead in the solar cell 20, so as to replace the solar cell 20 in time, which is beneficial to improving the reliability of the photovoltaic module 1.

[0076] In some embodiments, the monitoring module 33 includes a lead ion imprinted polymer.

[0077] The lead ion imprinted polymer is composed of a three-dimensional ordered porous lead ion imprinted polymer. This three-dimensional ordered porous lead ion imprinted polymer has a specific reflection front, which gives the lead ion imprinted polymer a structural color. The peak position of the reflection front of the lead ion imprinted polymer is related to the pore size of the lead ion imprinted polymer, so that the color of the lead ion imprinted polymer changes as the pore size of the lead ion polymer increases or decreases. Furthermore, the color of the lead ion imprinted polymer changes as the pore size of the lead ion polymer increases or decreases. When the pore size of the lead ion polymer increases or decreases, it is specifically manifested as the lead ion polymer expands or contracts. Therefore, the color of the lead ion imprinted sensor changes as the pore size of the lead ion polymer increases or decreases. Lead ion imprinted polymers can specifically identify lead ions. When lead ions overflow and are recognized by the lead ion imprinted polymers, a cross-linking reaction is triggered, causing the lead ion imprinted polymers to shrink, thereby reducing the pore size in the lead ion imprinted polymers, shifting the reflection front to the blue, and changing the color. That is, the color of the lead ion imprinted polymer changes, which can realize the monitoring of lead ion leakage.

[0078] It is understandable that lead ion imprinted polymers are easy to obtain and inexpensive, and are relatively sensitive to lead ion detection. Therefore, providing the monitoring module 33 with a lead ion imprinted polymer is beneficial to improving the sensitivity of lead ion monitoring and reducing the production cost of the photovoltaic module 1.

[0079] In some embodiments, as Figure 2 、 Figure 3 and Figure 4 As shown, the photovoltaic assembly 1 further includes a control module 40 , and the monitoring module 33 includes an ion selective electrode, which is electrically connected to the control module 40 .

[0080] The ion-selective electrode can be selective for heavy metals such as lead ions. When immersed in a solution containing the corresponding heavy metal ions, the ion-selective electrode interacts with the corresponding heavy metal ions, generating a potential change. This potential change is measured and converted into an electrical signal, which is then transmitted to the control module 40.

[0081] In this way, the control module 40 can promptly receive information about heavy metal leakage from the solar cell 20, and can promptly replace the solar cell 20 or process the leaked pollutants, so as to promptly stop the solar cell 20 from continuing to leak pollutants, thereby further reducing the pollution of the photovoltaic module 1 to the environment.

[0082] In some embodiments, as Figure 4 As shown, the photovoltaic assembly 1 further includes an energy storage module 60 , which is electrically connected to the control module 40 and is used to provide electrical energy to the control module 40 .

[0083] The working process of the control module 40 requires electric energy. The energy storage module 60 is electrically connected to the control module 40 , and the control module 40 can be charged in time through the energy storage module 60 .

[0084] Optionally, the energy storage module 60 may include a solar cell 20 to convert light energy into electrical energy and store it. Alternatively, the energy storage device may be electrically connected to the solar cell 20 of the photovoltaic assembly 1 to charge the energy storage device via the solar cell 20.

[0085] Therefore, an energy storage module 60 is provided, and the energy storage module 60 is electrically connected to the control module 40 so as to supply power to the control module 40 through the energy storage module 60 , which is beneficial to improving the reliability of the energy storage module 60 .

[0086] In some embodiments, as Figure 4 As shown, the photovoltaic assembly 1 further includes a communication module 50 , which is electrically connected to the control module 40 and is used to communicate with a control system outside the photovoltaic assembly 1 .

[0087] The communication module 50 may be an antenna or the like, and the control system outside the photovoltaic assembly 1 may be a control system for controlling the normal operation of the photovoltaic assembly 1 .

[0088] After obtaining the signal of heavy metal ions such as lead ions, the control module 40 can send a signal to the control system through the communication module 50 to notify the control system of the information that the solar cell 20 of the photovoltaic component 1 has leaked lead ions, so that the control system can promptly control the photovoltaic component 1 to perform corresponding control actions, or the control system can issue an alarm to facilitate the operator to replace the solar cell 20 in time.

[0089] In some embodiments, the photovoltaic assembly 1 further includes a power generation module, which is electrically connected to the control module 40 and is used to provide electrical energy to the control module 40 .

[0090] In this way, the control module 40 is powered by the power generation module, so as to improve the reliability of the control module 40 .

[0091] In some embodiments, the photovoltaic assembly 1 includes a plurality of pollution treatment components 30 , and the plurality of pollution treatment components 30 are spaced apart along the circumference of the frame 10 .

[0092] A plurality of pollutant treatment components 30 are arranged at intervals along the circumference of the frame 10 , and a plurality of diversion modules 31 and corresponding adsorption modules 32 are arranged at intervals, so that when rainwater flows to multiple positions of the frame 10 , it can always flow to the diversion module 31 via a shorter path, and flow to the adsorption module 32 under the guidance of the diversion module 31 .

[0093] Therefore, such a configuration is beneficial to reducing the risk of rainwater directly flowing into the environment through the frame 10, improving the reliability of rainwater being adsorbed by the adsorption module 32 in the pollutant treatment component 30, and further beneficial to reducing environmental pollution.

[0094] In some embodiments, as Figure 2 and Figure 3 As shown, the guide module 31 includes a guide groove 311, which is concave and has an opening 311a and a through hole 311b. The opening 311a is used for the fluid to flow in, and the through hole 311b is provided at the bottom of the guide groove 311 and is used to guide the fluid in the guide groove 311 to the adsorption module 32.

[0095] The guide groove 311 is concave, so after rainwater flows from the solar cell 20 into the frame 10 , it naturally flows into the guide groove 311 through the opening 311 a under the action of its own gravity, which is beneficial to improving the reliability of rainwater collection in the guide groove 311 .

[0096] The through hole 311 b may be provided at the bottom or side of the guide groove 311 so that the rainwater in the guide groove 311 flows to the adsorption module 32 through the through hole 311 b , so that the adsorption module 32 can absorb pollutants such as lead in the rainwater.

[0097] Therefore, the guide module 31 is provided to include a guide groove 311, and the guide groove 311 is provided to have an opening 311a and a through hole 311b, so that rainwater on the solar cell 20 is collected by the guide groove 311 and flows to the adsorption module 32, which is beneficial to improving the smoothness and reliability of the guide module 31 in guiding rainwater to the adsorption module 32.

[0098] In some embodiments, as Figure 2 and Figure 3 As shown, the pollutant treatment component 30 includes a first clamping portion 30a, a second clamping portion 30b and a connecting portion 30c. The first clamping portion 30a and the second clamping portion 30b are clamped to opposite sides of the frame 10, and the connecting portion 30c connects the first clamping portion 30a and the second clamping portion 30b, and intersects with the first clamping portion 30a and the second clamping portion 30b respectively.

[0099] The pollutant treatment component 30 includes a first clamping portion 30a and a second clamping portion 30b, and the first clamping portion 30a and the second clamping portion 30b are located on opposite sides of the frame 10, which is beneficial to improving the convenience and reliability of the connection between the pollutant treatment component 30 and the frame 10, and facilitating the maintenance and replacement of the pollutant treatment component 30.

[0100] In some embodiments, as Figure 2 and Figure 3As shown, the first clamping portion 30a is provided above the second clamping portion 30b, the guide groove 311 is provided on the first clamping portion 30a, and the adsorption module 32 is provided on the connecting portion 30c.

[0101] In this way, the guide groove 311 is provided on the first engaging portion 30a, and is located above the pollutant treatment component 30. Rainwater in the guide groove 311 can flow toward the adsorption module 32 located on the connecting portion 30c under its own gravity, so as to be absorbed by the adsorption module 32. Therefore, this arrangement helps to simplify the structure of the pollutant treatment component 30.

[0102] In a second aspect, the photovoltaic power generation system provided in an embodiment of the present application includes the photovoltaic assembly 1 provided in any of the above embodiments.

[0103] Optionally, the photovoltaic power generation system may be a small solar power supply system, a simple DC system, a large solar power supply system, an AC / DC power supply system, a grid-connected system, or a hybrid power supply system.

[0104] The photovoltaic power generation system provided in the embodiment of the present application has the same technical effects as the photovoltaic assembly 1 provided in any of the above embodiments, and thus will not be described in detail here.

[0105] In some embodiments, as Figures 1 to 4As shown, the photovoltaic assembly 1 provided in an embodiment of the present application includes a frame 10, solar cells 20, multiple pollutant treatment components 30, a control module 40, an energy storage module 60, and a communication module 50. The solar cells 20 are mounted on the frame 10, and the pollutant treatment components 30 are mounted on the frame 10. The pollutant treatment components 30 include a flow diversion module 31 and an adsorption module 32. The flow diversion module 31 is used to direct fluid to the adsorption module 32, and the adsorption module 32 is used to adsorb pollutants. The adsorption module 32 includes a lead ion adsorbent, which includes at least one of montmorillonite, activated carbon, diatomaceous earth, zeolite, molecular sieve, kaolin, metal-organic framework (MOF) materials, and covalent organic framework materials. The pollutant treatment components 30 also include a monitoring module 33, which is located between the flow diversion module 31 and the adsorption module 32 and is used to monitor pollutants. The monitoring module 33 includes a lead ion imprinted polymer and an ion-selective electrode, which is electrically connected to the control module 40. The energy storage module 60 is electrically connected to the control module 40 and is used to provide power to the control module 40. The communication module 50 is electrically connected to the control module 40 and is used to communicate with the control system outside the photovoltaic module 1. A plurality of pollutant treatment components 30 are spaced apart along the circumference of the frame 10. The flow guide module 31 includes a flow guide groove 311. The flow guide groove 311 is concave and has an opening 311a and a through hole 311b. The opening 311a is used for the inflow of fluid. The through hole 311b is provided at the bottom of the flow guide groove 311 and is used to guide the fluid in the flow guide groove 311 to the adsorption module 32. The pollutant treatment component 30 includes a first clamping portion 30a, a second clamping portion 30b and a connecting portion 30c. The first clamping portion 30a and the second clamping portion 30b are clamped to opposite sides of the frame 10. The connecting portion 30c connects the first clamping portion 30a and the second clamping portion 30b and intersects with the first clamping portion 30a and the second clamping portion 30b, respectively.
