For example, in perovskite crystalline silicon tandem cells, the interface area between the perovskite layer and the crystalline silicon substrate layer needs to withstand the dual effects of thermal expansion and light. Due to the differences in material properties of the perovskite layer and the crystalline silicon substrate layer, their thermal expansion coefficients are different, which can easily lead to stress at the interface, resulting in interface delamination, cracks or damage. In addition, the low carrier transmission efficiency at the interface will also lead to a decrease in photoelectric conversion efficiency.

[0045] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0046] Example 1

[0047] The emergence of perovskite materials has provided a new opportunity for the development of tandem cells. It has a wide light absorption range and high photoelectric conversion efficiency, so that the perovskite crystalline silicon tandem cell composed of a perovskite layer and a crystalline silicon base layer can theoretically break through the efficiency bottleneck of traditional silicon-based cells and achieve higher photoelectric conversion efficiency.

[0048] Although perovskite materials show extremely high photoelectric conversion efficiency under laboratory conditions, perovskite crystalline silicon tandem cells still face some severe challenges in practical applications. For example, in perovskite crystalline silicon tandem cells, the interface area between the perovskite layer and the crystalline silicon substrate layer needs to withstand the dual effects of thermal expansion and light. Due to the differences in material properties of the perovskite layer and the crystalline silicon substrate layer, their thermal expansion coefficients are different, which can easily lead to stress at the interface, resulting in interface delamination, cracks or damage. In addition, the low carrier transmission efficiency at the interface will also lead to a decrease in photoelectric conversion efficiency.

[0049] In view of the problem in the prior art that the thermal expansion coefficients of the perovskite layer and the crystalline silicon substrate layer are different, which easily leads to stress at the interface, and then interface delamination, cracks or damage occur, resulting in reduced stability and service life of the photovoltaic panel, this embodiment provides a photovoltaic panel, Figure 1 is a layered structure diagram of a photovoltaic cell panel according to an embodiment of the present invention, such as Figure 1 As shown, it includes a first conductive layer 1, a crystalline silicon substrate layer 2, a perovskite layer 5, a second conductive layer 7 and an electrode layer 8 arranged in sequence from bottom to top, and the photovoltaic cell panel also includes: an interface regulation layer 4, which is arranged between the crystalline silicon substrate layer 2 and the perovskite layer 5, and the interface regulation layer 4 is prepared from a composite material, and at least one component of the composite material contains a molecular group with a self-repairing function.

[0050] The photovoltaic cell panel of this embodiment has an interface regulation layer 4 arranged between the crystalline silicon base layer 2 and the perovskite layer 5. The interface regulation layer 4 is made of a composite material whose components include molecular groups with self-repairing functions. It can repair interface microcracks caused by thermal expansion and stress when the battery is working, thereby improving the stability and service life of the battery. In addition, the use of composite materials can promote the efficient migration of electrons and holes, reduce interface recombination losses, and thus improve the photoelectric conversion efficiency of the photovoltaic cell panel.

[0051] Under external stimulation (such as heat, light, and humidity), the amine group can re-bond with the newly formed defects to achieve self-repair. Therefore, the above-mentioned molecular group with self-repair function is an amine group. The molecular group with self-repair function is an amine group. In one embodiment of the present invention, the components of the composite material used to prepare the interface regulation layer 4 also include aluminum oxide and / or silicon nitride.

[0052] Since perovskite materials are sensitive to temperature, long-term exposure to high temperatures will cause degradation of the perovskite layer, thereby affecting the stability of the entire photovoltaic cell assembly. In order to solve the above problem, the above-mentioned photovoltaic cell panel also includes: a first thermal management layer 3, which is arranged between the interface regulation layer 4 and the crystalline silicon base layer 2. The first thermal management layer is made of a thermally conductive material and is used to conduct heat generated by the crystalline silicon base layer.

[0053] In order to improve the thermal conductivity, the first thermal management layer needs to use materials with good thermal conductivity as much as possible. Since aluminum nitride ceramics and alumina ceramics have high thermal conductivity, the first thermal management layer is prepared from at least one of the following materials: aluminum nitride ceramics and alumina ceramics, that is, the first thermal management layer is prepared by a single aluminum nitride ceramic or a single alumina ceramic, or aluminum nitride ceramics and alumina ceramics are mixed in a certain ratio to prepare the first thermal management layer.

[0054] The heat generated by the crystalline silicon base layer is conducted away through the first thermal management layer, but it cannot completely prevent the heat from being transferred to the upper layer. In order to dissipate this part of the heat, Figure 1 As shown, the photovoltaic cell panel further includes: a second thermal management layer 9, which is arranged on the electrode layer 8, Figure 2 is a schematic diagram of the surface structure of the second thermal management layer according to an embodiment of the present invention. Figure 2 As shown, the surface of the second thermal management layer has a micron-scale hole structure, which can effectively increase the heat dissipation area, promote the natural dissipation of heat, reduce the surface temperature of the battery, and thus improve the thermal stability of the photovoltaic panel.

[0055] In one embodiment of the present invention, the second thermal management layer 9 is made of polydimethylsiloxane material.

[0056] In order to enhance the light absorption efficiency of the perovskite layer and thus improve the power generation efficiency of photovoltaic panels, such as Figure 1 As shown, the photovoltaic cell panel further includes: a nanocrystalline grain enhancement layer 6, which is disposed between the perovskite layer 5 and the second conductive layer 7, and is used to reduce the reflection and scattering of light and improve the propagation path of light in the perovskite layer. The nanocrystalline grain enhancement layer is usually deposited by a solution method or a spin coating method, and its structure and material design enable light energy to be fully absorbed and converted into electrical energy.

[0057] In order to further improve the light absorption efficiency, preferably, the nanocrystalline grain enhancement layer is made of at least one of the following materials: titanium dioxide and silicon dioxide.

[0058] Example 2

[0059] The present embodiment provides a perovskite crystalline silicon stacked battery panel. The perovskite crystalline silicon stacked battery structure design of the present embodiment is composed of multiple functional layers, each layer is optimized according to its specific function, and works together to improve the photoelectric conversion efficiency, thermal stability and service life. The hierarchical order from bottom to top is: a bottom transparent conductive base layer, a crystalline silicon base layer, a thermal management layer, an interface regulation layer, a perovskite layer, a nano-grain enhancement layer, a highly transparent conductive layer and an electrode layer.

[0060] Transparent conductive substrate layer (i.e. the first conductive layer mentioned above): As the base layer of the entire battery structure, the transparent conductive substrate layer is located at the bottom and is made of materials with high transparency and good conductivity (such as indium tin oxide, ITO). This layer not only provides mechanical support for the battery, but also has excellent light transmittance, allowing sunlight to pass through and reach the crystalline silicon substrate layer, while ensuring that the battery current can be smoothly conducted from the substrate to the external circuit.

[0061] Crystalline silicon substrate layer (located above the transparent conductive substrate layer): The crystalline silicon substrate layer is the core photoelectric conversion layer of the stacked cell of this embodiment, and is made of single crystal silicon or polycrystalline silicon material. This layer is mainly responsible for absorbing and converting light energy from sunlight into electrical energy. The thickness of the crystalline silicon substrate layer is usually designed to be between 150 and 200 microns, which not only ensures its effective light absorption ability, but also enables efficient electrical conduction of charges. This layer is located above the transparent conductive substrate layer and forms the main electrical energy conversion part of the cell.

[0062] The first thermal management layer (located above the crystalline silicon base layer): The thermal management layer is one of the keys to the innovation of this embodiment, which aims to solve the problem of heat generated by the battery during operation. The thermal management layer consists of two parts: First, between the crystalline silicon base layer and the interface regulation layer, there is a layer of high thermal conductivity material, usually aluminum nitride (AlN) or other ceramic materials with high thermal conductivity. This material can quickly conduct the heat generated by the crystalline silicon base layer to prevent the battery from overheating and causing performance degradation. Secondly, a microporous coating (i.e., the second thermal management layer) is designed on the surface of the battery. The coating is coated with a high-temperature resistant polymer (such as polydimethylsiloxane PDMS). The surface of the coating has a micron-scale pore structure, which can effectively increase the heat dissipation area, promote the natural dissipation of heat, and reduce the surface temperature of the battery, thereby improving the thermal stability of the photovoltaic panel.

[0063] Interface regulation layer (located above the thermal management layer): The interface regulation layer is located between the thermal management layer and the perovskite layer. Its main function is to optimize the interface transmission between the crystalline silicon layer and the perovskite layer. This layer uses a composite material that can promote the efficient migration of electrons and holes and reduce interface recombination losses, thereby improving the photoelectric conversion efficiency of photovoltaic panels. In addition, the interface regulation layer also uses molecular groups with self-repairing functions (such as amine groups), which can repair interface microcracks caused by thermal expansion and stress when the battery is working, further improving the stability and service life of the battery.

[0064] Perovskite layer (located above the interface regulation layer): The perovskite layer is a key part of light absorption and electrical energy conversion in the battery. It is made of high-efficiency perovskite materials (such as CH3NH3PbI3 or other perovskite compounds). Perovskite materials have excellent light absorption properties and can efficiently absorb sunlight and convert it into electric charges. The thickness of the perovskite layer is generally set between 100 and 300 nanometers to achieve optimal light absorption and charge separation.

[0065] Nanocrystalline enhancement layer (located above the perovskite layer): This layer is designed to enhance the light absorption efficiency of the perovskite layer. The enhancement layer made of nanoparticles (such as titanium dioxide TiO2 or silicon dioxide SiO2) can effectively reduce the reflection and scattering of light and improve the propagation path of light in the perovskite layer. The nanocrystalline enhancement layer is usually deposited by solution method or spin coating method, and its structure and material design enable light energy to be fully absorbed and converted into electrical energy.

[0066] Highly transparent conductive layer (i.e. the second conductive layer mentioned above, located above the nanocrystalline grain enhanced layer): This layer is made of transparent conductive materials (such as PEDOT, poly (3, 4-ethylenedioxythiophene) - polystyrene sulfonate and indium tin oxide in a ratio of 9:1), and is mainly used to collect and conduct the current generated by the perovskite layer. It not only has good transparency to ensure the transmission rate of light energy, but also has high conductivity and can efficiently conduct current to the electrode layer.

[0067] Electrode layer (the top layer): The electrode layer is located at the top and is usually made of transparent conductive materials (such as ITO or FTO) or metal materials (such as silver and gold) to collect and conduct the battery's current. The electrode layer has good conductivity while ensuring light transmittance, thereby maximizing the efficiency of the battery.

[0068] In this embodiment, an interface regulation layer is set between the perovskite layer and the crystalline silicon base layer, using a bipolar composite material and introducing a self-repairing molecular group. Under high temperature conditions, the interface regulation layer can repair microcracks, reduce interface carrier recombination, improve photoelectric conversion efficiency, and significantly improve the stability of the interface; at the same time, multiple thermal management structures, including a high thermal conductivity material layer and a microporous coating design, are also set to efficiently export the heat generated during the working process to prevent the perovskite layer from overheating and decomposing. The microporous structure further promotes natural heat dissipation, relieves interface thermal stress, and effectively improves thermal stability; in addition, a nano-grain enhanced film layer is added between the perovskite and the crystalline silicon, and the light absorption path is optimized by the directional arrangement of nano-grains, reducing light reflection and scattering losses, and improving the overall photoelectric conversion efficiency. Through the design of the above layers and the selection of materials, the perovskite crystalline silicon stacked battery of this embodiment achieves the optimal combination of photoelectric conversion, thermal management and current collection, and maximizes the overall performance of the battery. In particular, under the innovative design of the thermal management layer, the thermal stability of the battery has been significantly enhanced, extending the service life of the battery and improving the efficiency in long-term work.

The interface regulation layer is made of a composite material whose components include molecular groups with self-repairing functions. It can repair interface microcracks caused by thermal expansion and stress when the battery is working, thereby improving the stability and service life of the battery. In addition, the use of composite materials can promote the efficient migration of electrons and holes, reduce interface recombination losses, and thus improve the photoelectric conversion efficiency of photovoltaic panels.

[0079] Since perovskite materials are sensitive to temperature, long-term exposure to high temperatures will cause degradation of the perovskite layer, thereby affecting the stability of the entire photovoltaic cell assembly.

[0081] The heat generated by the crystalline silicon base layer is conducted away through the first thermal management layer, but the heat transfer to the upper layer cannot be completely prevented. In order to dissipate this part of the heat, after the perovskite layer, the second conductive layer and the electrode layer are sequentially manufactured on the interface regulation layer, the preparation method further includes: manufacturing a second thermal management layer on the electrode layer, and the surface of the second thermal management layer has a micron-scale pore structure.
