[0002] The use of solar cell modules (solar panels) is rapidly increasing in order to reduce environmental impact and as a result of government and local government policies. However, it is expected that a large number of solar cell panels will be generated that have reached the end of their useful life. Therefore, rather than simply discarding solar cell modules that have reached the end of their useful life, technologies have been proposed for recycling the various materials used in solar cell modules. For example, Patent Document 1 discloses a method for recycling solar cell panels, which includes a process of separating EVA (ethylene-vinyl acetate copolymer) resin used as an encapsulant, protective glass, solar cell elements and wiring members, and a back surface protective material.

[Figure 6] 10 is a flowchart showing a flow of information processing by an information processing device. DETAILED DESCRIPTION OF THE INVENTION

[0021] An example of an embodiment of the present disclosure will be described below with reference to the drawings. The same reference numerals are used throughout the drawings to designate identical or equivalent components and parts. The dimensional proportions of the drawings are exaggerated for illustrative purposes and may differ from the actual proportions.

[0022] FIG. 1 is a diagram showing an overview of an information processing device according to this embodiment. The information processing device 10 according to this embodiment is a device that determines a method for disposing of a sealant used in a solar cell module 1. Disposal methods for the sealant used in the solar cell module 1 include, for example, reuse as a sealant, recycling into another product, disposal, and incineration. Note that materials for the sealant used in the solar cell module 1 include EVA resin and ionomer. When the material for the sealant used in the solar cell module 1 includes an ionomer, the sealant may not include a coupling agent.

[0023] In order to recover the encapsulant from the solar cell module 1, it is necessary to remove the components used in the solar cell module 1, such as the protective glass, solar cell elements, wiring members, and back surface protection material. However, it is time-consuming to determine the disposal method for the encapsulant provided in the solar cell module 1 after removing the components, such as the solar cell elements, wiring members, and back surface protection material.

[0024] Therefore, the information processing device 10 acquires usage status information, which is information related to the usage status of the sealing material of the solar cell module 1. Then, the information processing device 10 determines a treatment method for the sealing material used in the solar cell module 1 using the acquired usage status information and deterioration information related to deterioration of the properties of the sealing material of the solar cell module, such as electrical properties, mechanical properties, and optical properties, which has been prepared in advance. By determining a treatment method for the sealing material used in the solar cell module 1 using the deterioration information and usage status information, the information processing device 10 can indicate a treatment method for the sealing material provided in the solar cell module 1 without disassembling the solar cell module 1.

[0025] FIG. 2 is a block diagram showing the hardware configuration of the information processing device 10. As shown in FIG.

[0026] 2, the information processing device 10 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a storage 14, an input unit 15, a display unit 16, and a communication interface (I / F) 17. Each component is connected to each other via a bus 19 so as to be able to communicate with each other.

[0027] The CPU 11 is a central processing unit that executes various programs and controls each component. That is, the CPU 11 reads programs from the ROM 12 or storage 14 and executes the programs using the RAM 13 as a work area. The CPU 11 controls the above components and performs various arithmetic processing in accordance with the programs recorded in the ROM 12 or storage 14. In this embodiment, the ROM 12 or storage 14 stores an information processing program that determines and presents a method for treating the encapsulant provided in the solar cell module 1 without disassembling the solar cell module 1.

[0028] The ROM 12 stores various programs and various data. The RAM 13 temporarily stores programs or data as a working area. The storage 14 is configured with a storage device such as an HDD (Hard Disk Drive), SSD (Solid State Drive), or flash memory, and stores various programs including the operating system and various data.

[0029] The input unit 15 includes a pointing device such as a mouse and a keyboard, and is used to perform various inputs.

[0030] The display unit 16 is, for example, a liquid crystal display, and displays various information. The display unit 16 may also function as the input unit 15 by adopting a touch panel system.

[0031] The communication interface 17 is an interface for communicating with other devices, and uses standards such as Ethernet (registered trademark), FDDI, and Wi-Fi (registered trademark).

[0032] When executing the above information processing program, the information processing device 10 uses the above hardware resources to realize various functions. The functional configuration realized by the information processing device 10 will be described.

[0033] FIG. 3 is a block diagram showing an example of the functional configuration of the information processing device 10. As shown in FIG.

[0034] 3, the information processing device 10 has, as functional components, an acquisition unit 101, a determination unit 102, and a presentation unit 103. Each functional component is realized by the CPU 11 reading and executing an information processing program stored in the ROM 12 or the storage 14.

[0035] The acquisition unit 101 acquires usage status information, which is information related to the usage status of the sealing material of the solar cell module 1 that includes the sealing material to be determined by the determination unit 102. Examples of the usage status information include information on the cumulative power generation amount of the solar cell module 1, information on the cumulative amount of sunlight irradiated onto the solar cell module 1, information on the cumulative temperature of the solar cell module 1, information on the temperature history of the solar cell module 1, and information on the operating time of the solar cell module 1. All of this information is correlated with the degree of deterioration of the sealing material used in the solar cell module 1. Therefore, by acquiring the usage status information, the acquisition unit 101 enables the determination unit 102 to determine a treatment method for the sealing material to be determined without disassembling the solar cell module 1.

[0036] The determination unit 102 determines a treatment method for the encapsulant used in the solar cell module 1 using deterioration information related to deterioration of pre-prepared solar cell module characteristics, such as the output characteristics of the solar cell module, or the characteristics of the encapsulant of the solar cell module, such as the electrical, mechanical, and optical characteristics, and the usage information acquired by the acquisition unit 101. For example, the determination unit 102 determines a treatment method for the encapsulant based on the degree of deterioration of the encapsulant of the solar cell module 1 estimated using the deterioration information from the usage information acquired by the acquisition unit 101. The degree of deterioration of the encapsulant of the solar cell module 1 refers to the degree of deterioration of the electrical, optical, and mechanical characteristics of the encapsulant. More specifically, the determination unit 102 determines a treatment method for the encapsulant based on whether the degree of deterioration of the encapsulant used in the solar cell module 1 estimated using the deterioration information from the usage information exceeds a predetermined threshold. For example, if the degree of deterioration of the sealing material used in the solar cell module 1, as estimated from the usage information, exceeds a predetermined first threshold (i.e., if the degree of deterioration of the sealing material is relatively small), the determination unit 102 determines that the disposal method should be reused as a sealing material.Furthermore, if the degree of deterioration of the sealing material used in the solar cell module 1, as estimated from the usage information of the sealing material in the solar cell module 1, is equal to or less than the predetermined first threshold but exceeds a second threshold (i.e., if the degree of deterioration of the sealing material is relatively medium), the determination unit 102 determines that the disposal method should be recycled into another product.Furthermore, if the degree of deterioration of the sealing material used in the solar cell module 1, as estimated from the usage information of the sealing material in the solar cell module 1, is equal to or less than the predetermined second threshold but exceeds a third threshold (i.e., if the degree of deterioration of the sealing material is relatively large), the determination unit 102 determines that the disposal method should be discarded. Furthermore, if the degree of deterioration of the sealing material used in the solar cell module 1, as estimated from the usage information of the sealing material in the solar cell module 1, is equal to or less than a predetermined third threshold (i.e., if the degree of deterioration of the sealing material is significantly large), the judgment unit 102 judges that the disposal method should be incineration.

[0037] The deterioration information used by the determination unit 102 for determination includes information indicating a relationship with at least one of information on the cumulative power generation amount of the solar cell module, information on the cumulative amount of sunlight irradiated onto the solar cell module, information on the cumulative temperature of the solar cell module, information on the temperature history of the solar cell module, and information on the operating time of the solar cell module. The determination unit 102 can determine the treatment method for the sealing material used in the solar cell module 1 by estimating the degree of deterioration of the sealing material of the solar cell module 1 from the usage information of the sealing material of the solar cell module 1 and the deterioration information.

[0038] A specific example of degradation information used when the determining unit 102 determines the treatment method for the encapsulant provided in the solar cell module 1 will be described. The mechanical properties and optical performance of the encapsulant deteriorate depending on the usage conditions of the solar cell module. Specifically, the longer the solar cell module is used, the more the mechanical properties such as elongation at break and tensile strength at break, and the optical performance such as yellowness index of the encapsulant used in the solar cell module deteriorate. EVA resin was produced as the encapsulant under the conditions in Table 1 below, and the degree of degradation due to light irradiation and moisture was measured in a weatherometer test. The results are shown in Table 2. The test conditions for the weatherometer test were 60 minutes of irradiation (180 W / m) in an environment with a temperature of 60°C. 2 The test consisted of repeated exposure to sunlight (300-400 nm) and a 60-minute shower. 100 hours of these test conditions was equivalent to 5 years of outdoor exposure of a solar cell module.

[0039] [Table 1]

[0040] [Table 2]

[0041] Examples of coupling agents in Table 1 include silane coupling agents having a vinyl group, an amino group, or an epoxy group and a hydrolyzable group such as an alkoxy group. Among them, vinyltrimethoxysilane, γ-methacryloxypropyltrimethoxysilane, γ-methacryloxypropylmethyldimethoxysilane, γ-acryloxypropyltrimethoxysilane, γ-glycidoxypropyltrimethoxysilane, 3-glycidoxypropylmethyldimethoxysilane, 3-glycidoxypropylmethyldiethoxysilane, N-2-(aminoethyl)3-aminopropyltrimethoxysilane, N-2-(aminoethyl)3-aminopropylmethyldiethoxysilane, 3-aminopropyltrimethoxysilane, 3-aminopropyltriethoxysilane, N-phenyl-3-aminopropyltrimethoxysilane, and N-phenyl-3-aminopropyltriethoxysilane are listed. The silane coupling agent can be contained in an amount of usually 5 parts by mass or less, preferably 0.02 to 3 parts by mass, per 100 parts by mass of the ethylene-unsaturated carboxylic acid copolymer or its ionomer. When the silane coupling agent is contained in the above range, the adhesion between the multilayer sheet and the protective material or solar cell element, etc. can be further improved.

[0042] That is, as shown in Table 2, the values ​​of the elongation at break, tensile strength at break, and yellowness index change as the usage time of the solar cell module increases. Therefore, the determination unit 102 can determine a method for treating the encapsulant provided in the solar cell module 1 by comparing preset thresholds for reuse, recycling, and disposal with the degree of deterioration of the encapsulant of the solar cell module 1 estimated from the usage time of the solar cell module 1 using the data shown in Table 2.

[0043] A specific example of degradation information used by the determining unit 102 to determine a treatment method for the sealant provided in the solar cell module 1 will be described. The electrical characteristics of the sealant deteriorate depending on the usage conditions of the solar cell module. Specifically, the longer the solar cell module is used, the more the electrical characteristics of the solar cell module, such as the maximum output and short-circuit current, deteriorate.

[0044] Figure 4 is a graph showing the change in maximum output of a solar cell module over time, and Figure 5 is a graph showing the change in short-circuit current of a solar cell module over time. In Figures 4 and 5, "IONOMER" shows the change when an ionomer is used as the encapsulant, while "POE-1" and "POE-2" show the change when a polyolefin elastomer (POE) is used as the encapsulant.

[0045] That is, as shown in Figures 4 and 5, the longer the solar cell module is used, the more the maximum output and short-circuit current values ​​change. Therefore, the determination unit 102 can determine a method for treating the encapsulant provided in the solar cell module 1 by comparing preset thresholds for reuse, recycling, and disposal with the degree of deterioration of the encapsulant of the solar cell module 1 estimated from the maximum output and short-circuit current values ​​of the solar cell module 1 using the data shown in Figures 4 and 5.

[0046] The above-described determination by the determining unit 102 is an example, and the present disclosure is not limited to this example. Other usage information can also be used to determine the treatment method for the sealant.

[0047] The determination unit 102 may use a trained model generated in advance by machine learning when determining a treatment method for the sealant provided in the solar cell module 1 using the deterioration information and the usage status information acquired by the acquisition unit 101. That is, the determination unit 102 may input the above-mentioned deterioration information into the trained model, obtain output from the trained model, and determine a treatment method for the sealant provided in the solar cell module 1 based on the output from the trained model. In this case, the trained model may be a model trained using the usage status information acquired by the acquisition unit 101. Furthermore, the trained model may be stored in any location, such as inside the information processing device 10 or on a server external to the information processing device 10.

[0048] The determination unit 102 determines the treatment method of the sealing material provided in the solar cell module 1 using the deterioration information and the usage status information acquired by the acquisition unit 101, thereby making it possible to determine the treatment method of the sealing material provided in the solar cell module 1 without disassembling the solar cell module 1.

[0049] The presentation unit 103 presents the determination result by the determination unit 102 on the display unit 16. For example, if the determination unit 102 determines that the processing method is to reuse the sealant as a sealant, the presentation unit 103 presents the message "This sealant can be reused as a sealant" on the display unit 16. Also, for example, if the determination unit 102 determines that the processing method is to recycle the sealant into another product, the presentation unit 103 presents the message "This sealant can be recycled into another product" on the display unit 16.

[0050] When presenting the determination result by the determination unit 102 on the display unit 16, the presentation unit 103 may input the determination result to a large-scale language model (LLM) and use the output from the large-scale language model.

[0051] Next, the operation of the information processing device 10 will be described.

[0052] 7 is a flowchart showing the flow of information processing by the information processing device 10. The information processing is performed by the CPU 11 reading out an information processing program from the ROM 12 or storage 14, expanding it into the RAM 13, and executing it. The information processing shown in FIG. 4 is performed at any timing when determining the processing method for the sealing material provided in the solar cell module 1.

[0053] In step S101, the CPU 11 acquires usage status information, which is information related to the usage status of the sealing material of the solar cell module 1. As described above, the usage status information includes, for example, information on the cumulative power generation amount of the solar cell module 1, information on the cumulative amount of sunlight irradiated onto the solar cell module 1, information on the cumulative temperature of the solar cell module 1, information on the temperature history of the solar cell module 1, information on the operating time of the solar cell module 1, etc.

[0054] Following step S101, in step S102, CPU 11 uses the deterioration information and the usage status information acquired in step S101 to determine a treatment method for the sealant provided in solar cell module 1. More specifically, in step S102, CPU 11 determines a treatment method for the sealant provided in solar cell module 1 based on whether the degree of deterioration of the sealant used in solar cell module 1, estimated from the usage status information using the deterioration information, exceeds a predetermined threshold. Specifically, CPU 11 determines a treatment method for the sealant provided in solar cell module 1 by executing the processing of determination unit 102 described above.

[0055] Following step S102, in step S103, the CPU 11 displays on the display unit 16 the sealing material processing method determined in step S102.

[0056] The CPU 11 uses the acquired usage information to determine the processing method of the sealing material used in the solar cell module 1, making it possible to determine the processing method of the sealing material provided in the solar cell module 1 without disassembling the solar cell module 1.

[0057] The information processing device 10 may acquire the usage status information from another sealing material placed in the environment in which the sealing material provided in the installed solar cell module 1 is placed. The other sealing material may be made of the same material as the sealing material installed in the solar cell module 1. In this case, the acquisition unit 101 acquires the characteristics (electrical characteristics, optical characteristics, or mechanical characteristics) of the other sealing material as the usage status information, and the determination unit 102 determines the treatment method for the sealing material provided in the solar cell module 1 from the deterioration information and the characteristics of the other sealing material. This allows the information processing device 10 to determine the treatment method for the sealing material provided in the solar cell module 1 without disassembling the solar cell module 1.

In other words, the technology according to the present disclosure may achieve other effects that are obvious to a person skilled in the art of the present disclosure from the description in the above embodiments, in addition to or instead of the effects described in the above embodiments.

[0060] In the above embodiments, the information processing performed by the CPU after reading the software (program) may be performed by various processors other than the CPU.

The information processing may be performed by one of these processors, or by a combination of two or more processors of the same or different types (e.g., multiple FPGAs, or a combination of a CPU and an FPGA). The hardware structure of these processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor devices.

[0061] In addition, in each of the above embodiments, the information processing program is described as being pre-stored (installed) in a ROM or storage, but this is not limiting.
