[0039] However, the photovoltaic glass in the prior art is covered on the surface of the solar cell panel, and light directly passes through the photovoltaic glass to irradiate into the solar panel.

[0040] In order to solve the above technical problems, the present disclosure provides a solar cell module and a solar photovoltaic system, which can effectively utilize the sunlight incident into the gaps between the multiple units of the solar cell panel and reduce the reflection loss of the incident sunlight.

[0041] Embodiment 1

[0042] As Figure 1 andFigure 2 As shown, a solar cell module includes a cell panel 1, a glass 2, and a first reflective layer 4, the cell panel 1 includes a plurality of cell units 11 connected together; the glass 2 is arranged on one side of the cell panel 1, and a plurality of spherical cap-shaped protrusions 3 are arranged on the glass 2, the spherical cap-shaped protrusions 3 and the cell units 11 are one-to-one corresponding; the first reflective layer 4 is arranged in the gap between every two adjacent spherical cap-shaped protrusions 3 of the glass 2.

[0043] The cell panel 1 is a key device for directly converting sunlight into electrical energy. The cell panel 1 is composed of a plurality of cell units 11, and these units can have different structures and types. Specifically, the cell unit 11, i.e. the solar cell unit 11, is the most basic structural unit of the cell panel 1, which is composed of one or more layers of semiconductor material, most commonly silicon, which generates an electric current when sunlight shines on it. In order to generate sufficient power output, a plurality of solar cell units 11 are connected in series or parallel through connecting parts 12 to form a cell string or a cell group. More specifically, the connecting part 12 can be a thin strip or a strip of conductive material for realizing the electrical connection between solar cells. In order to protect the solar cells from the environment, the cell panel 1 can be encapsulated between a transparent glass 2 front panel and a back panel, and bonded with a material such as EVA (ethylene-vinyl acetate copolymer) adhesive film.

[0044] More specifically, the solar cell units 11 can be of multiple types. For example, the solar cell units 11 can be monocrystalline silicon solar cells, made from very high purity single crystal silicon wafers, with the highest efficiency. The solar cell units 11 can also be polycrystalline silicon solar cells, made from crystalline silicon formed after cooling silicon in a molten state, with slightly lower efficiency but lower cost. The solar cell units 11 can also be thin-film solar cells, and more specifically, can be amorphous silicon (a-Si), using chemical vapor deposition (CVD) or other methods to deposit amorphous silicon thin films on a substrate; can be cadmium telluride (CdTe), using cadmium telluride as the main material, with good flexibility and lower cost; can be copper indium gallium selenide (CIGS), an alloy thin film composed of copper, indium, gallium, and selenium, with good conversion efficiency and flexibility. The solar cell units 11 can also be perovskite solar cells, using materials with perovskite structure, with high theoretical efficiency and low cost potential, and is one of the research hotspots in recent years. The solar cell units 11 can be multi-junction solar cells: combining multiple materials, can capture different wavelengths of light spectrum within one cell, thus improving efficiency. Each type of solar cell has its specific application scenarios, and the choice of which type of cell depends on factors such as intended use, cost budget, and performance requirements. For example, for space applications, high-efficiency multi-junction solar cells can be preferred; while for ground-mounted large-scale photovoltaic power stations, polycrystalline silicon or thin-film solar cells with higher cost-effectiveness can be preferred. As long as the solar cell units 11 can generate current when sunlight shines on them, the specific structure of the solar cell units 11 is not limited.

[0045] Glass 2 is a structure that protects the internal solar cell units 11 and at the same time ensures light transmittance. Specifically, glass 2 can be super white glass 2, which contains very low iron content and thus has very high transparency, minimizing the absorption of incident light and thus allowing more light to pass through glass 2 to reach the solar cell units 11. Glass 2 can also be tempered glass 2, also known as strengthened glass 2, which is treated by heating and then rapidly cooling, causing the surface to form compressive stress and the interior to form tension. The glass 2 thus treated is more resistant and less likely to break, and even if it breaks, it breaks into small particles, reducing the risk of injury. More specifically, glass 2 can be photovoltaic glass 2. Glass 2 can also be anti-reflective coated glass 2, which has one or more thin films on its surface that reduce the reflection of light on the surface of glass 2, thus increasing the light transmittance and allowing more light to enter the solar panel 1. Glass 2 can also be low-iron glass 2: similar to super white glass 2, but emphasizing its low iron content to reduce the green tint and increase light transmittance. Glass 2 can also be double-sided glass 2: some high-performance solar panels 1 use double-sided glass 2 design, which protects both the front solar cells and provides additional protection on the back, suitable for solar panels 1 that generate electricity on both sides. Solar panels 1 used outdoors can choose tempered glass 2 with better weather resistance and mechanical strength, while in applications where the highest efficiency is sought, super white glass 2 or anti-reflective coated glass 2 with higher light transmittance and better anti-reflective effect can be chosen. As long as glass 2 can protect solar cell units 11 and at the same time ensure light transmittance, the material and type of glass 2 are not specifically limited.

[0046] The spherical cap-shaped protrusions 3 are protrusions with a spherical cap-shaped outer surface, which are a special type of convex lens designed to optimize the light capture ability of the solar panel 1. The characteristic of this structure is that it changes the way light behaves when it enters the solar panel 1, allowing more light to be effectively captured and converted into electrical energy. Specifically, the basic shape of the spherical cap-shaped protrusions 3 is similar to a part of a sphere, i.e. a piece cut from a spherical surface. This shape effectively changes the direction of the light, allowing it to be focused on the center of the cell units 11 and the surrounding area after entering the spherical cap-shaped protrusions 3. The height and spacing of the protrusions can be adjusted according to the specifications of the solar cells used and the desired light capture efficiency. The protrusions can be arranged in a regular array or randomly distributed, with regular arrangement helping to control the behavior of light and random distribution sometimes avoiding light interference patterns.

[0047] More specifically, the spherical cap-shaped protrusions 3 can be arranged in a single layer, each protrusion existing independently, for optimizing light absorption at a specific angle. The spherical cap-shaped protrusions 3 can be arranged in a multi-layer structure, with multiple protrusions stacked at the same location, forming a hierarchical structure, which helps to improve light absorption efficiency over a wider range of incident angles. More specifically, the spherical cap-shaped protrusions 3 can be integrated with the glass 2 as a monolithic structure, or can be a separate structure, with the bottom plane of the spherical cap-shaped protrusions 3 fixedly connected to the plane of the glass 2. When the spherical cap-shaped protrusions 3 and the glass 2 are separate structures, the materials of the spherical cap-shaped protrusions 3 and the glass 2 can be different. For example, the glass 2 can be made of super-white glass 2 or anti-reflective coated glass 2 to improve light transmittance and anti-reflective effect, and the spherical cap-shaped protrusions 3 can be made of tempered glass 2 with better mechanical strength to improve weather resistance.

[0048] The first reflective layer 4 is an important component in the design of the solar panel 1, and its purpose is to further improve the light absorption efficiency. This reflective layer is located between the protrusions or recesses on the surface of the glass 2, and reflects the light that is not immediately absorbed into the protrusions, and then refracts it into the cell units 11, thereby increasing the probability of photon capture. The reflective layer is located in the gaps between the spherical cap-shaped protrusions 3 of the glass 2 of the solar panel 1, which ensures that the incident light still has a chance to be absorbed by the cell units 11 after one or more reflections. Specifically, the reflective layer can be made of a variety of materials with a reflectivity of more than 90%, including but not limited to metals (such as silver, aluminum), high-reflectivity ceramic materials, or other high-reflectivity coating materials. The choice of these materials is based on their reflectivity, durability, and cost. More specifically, metal materials (such as aluminum or silver) can be used as the reflective layer, which have high reflectivity and can effectively reflect light back to the cell units 11; a multi-layer dielectric reflective layer can also be used, which is made of multiple layers of dielectric materials with different refractive indices, and the optimal reflection effect is achieved by designing a specific number of layers and thickness. This type of reflective layer can achieve high reflectivity over a wide wavelength range. A nanostructured reflective layer can also be used, which uses nanotechnology to manufacture a reflective layer with special structures such as nanowires, nanoparticles, or nanopores, etc. These structures can provide higher reflection efficiency and can adapt to different angles of incident light. A photonic crystal reflective layer can also be used: this reflective layer has a periodic arrangement of structures that can selectively reflect light within a specific wavelength range, thereby improving light utilization. As long as the first reflective layer 4 can reflect sunlight, the specific structure of the first reflective layer 4 is not limited.

[0049] By the above technical solutions, the solar cell module provided by the present disclosure sets multiple spherical cap-shaped protrusions 3 on the glass 2 of the cell panel 1, and makes the positions of the spherical cap-shaped protrusions 3 and the cell units 11 one-to-one corresponding, so that the sunlight passing through the protrusions can be focused on the cell units 11; and sets a reflective layer in the gap between every two adjacent spherical cap-shaped protrusions 3 of the glass 2, so that the sunlight incident in the gap between the adjacent two spherical cap-shaped protrusions, i.e. the sunlight in the gap between the multiple units of the solar cell panel, can be reflected into the spherical cap-shaped protrusions 3 and focused on the cell units 11 near the focal point of the spherical cap-shaped protrusions 3 for photoelectric conversion, effectively utilizing the sunlight incident in the gap between the multiple units of the solar cell panel and reducing the reflection loss of the sunlight incidence.

[0050] In some embodiments, the solar cell module further comprises a second reflective layer 5 arranged around the glass 2. The second reflective layer 5 can also be selected from a variety of materials with a reflectivity of more than 90%, including but not limited to metals (such as silver, aluminum), high-reflectivity ceramic materials or other high-reflectivity coating materials. The four sides of the glass 2 refer to the edge area of the glass 2 surface where no spherical cap-shaped protrusions 3 are arranged. Arranging the second reflective layer 5 around the glass 2 can reduce the light loss in the edge area and reflect more light into the spherical cap-shaped protrusions 3 and guide it to the cell units 11, thereby improving the overall photoelectric conversion efficiency.

[0051] In some embodiments, multiple baffles 6 are arranged around the cell panel 1, and the multiple baffles 6 are arranged close to one side of the cell panel 1 and provided with a third reflective layer. The baffles 6 can reduce the loss of light in the edge area and redirect more light to the cell units 11, thereby improving the overall photoelectric conversion efficiency. Specifically, the baffles 6 can be made of a variety of materials, including metals (such as aluminum alloy), engineering plastics (such as polycarbonate PC, acrylic PMMA), composite materials, etc. The baffles 6 can be connected with the cell panel 1 or not, for example, the baffles 6 can be connected with the support to support the baffles 6 around the cell panel 1.

[0052] More specifically, the shape of the baffle 6 can have various forms, for example, it can be a flat baffle 6, the baffle 6 is flat, used to provide basic edge protection and structural support; it can also be an inclined baffle 6: the baffle 6 is designed to be inclined at an angle, which can help better guide the light and facilitate drainage, reducing the possibility of water accumulation; it can also be an arc-shaped baffle 6, the baffle 6 can be designed to be arc-shaped, the baffle 6 can be curved towards the side close to or away from the solar panel 1, the baffle 6 curved towards the side close to the solar panel 1 can better reflect the light in the edge area back to the center of the solar panel 1, thereby improving the utilization efficiency of light. The baffle 6 curved towards the side away from the solar panel 1 helps rainwater to drain quickly, reducing the possibility of water accumulation; it can also be a polygonal baffle 6: the baffle 6 can be designed to be polygonal, such as triangular or trapezoidal, which can increase the stability of the structure and help optimize the reflection path of light; it can also be a jagged baffle 6, the edge of the baffle 6 is designed to be jagged, which can increase the reflection area and help reflect more light back to the solar panel 1.

[0053] In some embodiments, the baffle 6 and the solar panel 1 are fixedly connected, and the included angle between the baffle 6 and the solar panel 1 is a right angle or an obtuse angle. The baffle 6 and the solar panel 1 can be fixedly connected in various ways, for example, the baffle 6 and the solar panel 1 can be screw-connected, for example, using screws to fix the baffle 6 on the frame of the solar panel 1, which is simple and reliable, easy to disassemble and maintain; it can also be welded, the baffle 6 can be permanently fixed on the frame of the solar panel 1 by welding, which is suitable for baffle 6 made of metal material, and the welded connection is very firm and does not need to worry about loosening. It can also be adhesively connected, using high-strength adhesive to bond the baffle 6 and the solar panel 1 together, which is suitable for various materials and is easy to install, without visible fixing parts and a neat appearance. Fixedly connecting the baffle 6 and the solar panel 1 can make the baffle 6 stably connected to the solar panel; setting the included angle between the baffle 6 and the solar panel 1 to a right angle or an obtuse angle can make the baffle 6 receive more sunlight at different angles, which helps to reflect more light back to the solar panel 1.

[0054] More specifically, as shown in Figure 2 and Figure 3 When the included angle between the baffle 6 and the solar panel 1 is a right angle, a cover plate 8 can be installed on top of the baffle 6 to protect the glass 2 when not in use and prevent the glass 2 from being damaged. Of course, the cover plate 8 can also be made of transparent material, such as tempered glass 2, in which case the cover plate 8 can also be installed on top of the baffle 6 when in use to protect the glass 2 and the battery cells 11. More specifically, the back panel can protrude one circle from the solar panel 1, and the side wall of the baffle 6 is fixedly connected to the protruding part of the back panel, thereby protecting the entire solar panel 1 and the glass 2.

[0055] In some embodiments, the baffle 6 and the solar panel 1 can also be detachably connected in various ways such as snap connection, sliding rail connection, and latch connection, etc., to facilitate the replacement of the baffle 6 at any time.

[0056] In some embodiments, the baffle 6 is dampedly connected to the solar panel 1, allowing the baffle 6 to rotate to a certain extent relative to the solar panel 1, and the speed and stability of rotation are controlled through a damping mechanism. Specifically, the baffle 6 can be connected to the solar panel 1 through a rotating shaft. A damper is installed on the rotating shaft to control the rotation speed of the baffle 6; a hinge with damping function can also be used to connect the baffle 6 and the solar panel 1, so that the baffle 6 can rotate within a certain angle range. The baffle 6 and the solar panel 1 can also be connected through a spring-loaded damping mechanism. The spring can provide a certain elastic support, and the damper controls the rotation speed. More specifically, the damper can be a hydraulic damper, which uses liquid flow to generate resistance and control the rotation speed of the baffle 6; it can also be a viscous damper, which achieves damping effect through the flow of viscous substances; it can also be a friction damper, which generates resistance through the friction between two surfaces. It can also be a magneto-rheological damper: it uses magnetic field to change the viscosity of fluid to control the damping effect. The baffle 6 is dampedly connected to the solar panel 1, and the position of the baffle 6 can be adjusted to optimize the reflection path of light and improve the light absorption efficiency of the solar panel 1. The baffle 6 can be automatically or manually adjusted as the position of the sun changes to adapt to different lighting conditions. The damping mechanism can reduce the influence of external forces such as wind on the baffle 6, reducing the risk of structural damage. Proper rotation design can make the baffle 6 fold up when not in use, reducing the occupied space and improving the overall aesthetics.

[0057] In some embodiments, the baffle 6 is connected to the solar panel 1 through a rotating shaft, and the rotating shaft is connected to a drive motor. This structure allows the baffle 6 to automatically adjust its position as needed, thereby optimizing the reflection path of light and improving the light absorption efficiency of the solar panel 1. Specifically, the baffle 6 is connected to the frame of the solar panel 1 through one or more rotating shafts. The rotating shafts can be installed at both ends of the baffle 6, allowing the baffle 6 to rotate around the rotating shafts. The rotating shafts can be made of high-strength materials such as stainless steel or aluminum alloy to ensure they have sufficient mechanical strength and corrosion resistance. More specifically, the drive motor includes a stepper motor, a servo motor, etc., which have high precision and controllability. The motor can be installed at one end or both ends of the rotating shaft, and the appropriate installation position is selected according to actual needs. The motor is connected to the rotating shaft through gears, belts, or direct connection, etc., to transmit power. The drive motor drives the rotating shaft to rotate, thereby driving the baffle 6 to rotate, thereby controlling the rotation angle of the baffle 6.

[0058] More specifically, a light-sensitive sensor and a position sensor can also be provided on the baffle 6. Specifically, the light-sensitive sensor can be provided on the third reflective layer for detecting the direction and intensity of light to determine the optimal position of the baffle 6. The position sensor is installed near the rotating shaft and can directly detect the rotation angle of the baffle 6 for feedback of the actual position of the baffle 6 to ensure that the baffle 6 rotates at a predetermined angle. The light-sensitive sensor, the position sensor, and the driving motor are all connected to the controller, and the light-sensitive sensor and the position sensor transmit signals to the controller, which controls the rotation of the baffle 6, so that the angle can be automatically adjusted according to the change of the sun position, ensuring that more light is reflected onto the solar panel 1 and improving the photoelectric conversion efficiency.

[0059] In some embodiments, the shape of the spherical cap-shaped protrusions 3 is a hemispherical structure. A hemispherical structure is a special type of spherical cap structure, that is, when the height of the spherical cap is exactly equal to half the diameter of the sphere, the spherical cap becomes a hemisphere. Each protrusion is a hemisphere, which means that they gradually widen from top to bottom, forming a shape similar to half a sphere. The hemispherical structure is higher than other types of spherical cap structures and can receive more angles of reflected light and refract it onto the solar panel 1, improving the photoelectric conversion efficiency.

[0060] In some embodiments, the solar cell assembly further comprises a heat sink 7 provided on the side of the panel 1 away from the glass 2; the heat sink 7 is in contact with the position corresponding to the center of the spherical cap-shaped protrusion 3 on the side of the panel 1.

[0061] The main purpose of the heat sink 7, which is usually installed on the side of the panel 1 away from the glass 2, is to effectively remove the heat generated by the panel 1 during operation. Photovoltaic cells generate heat during the conversion of light energy into electrical energy, which can cause the temperature of the cells to rise if not removed in time, thereby affecting the efficiency and lifespan of the cells. The heat sink 7 can achieve heat dissipation in various ways, such as natural convection cooling, forced air cooling, and liquid cooling. Natural convection cooling relies on the natural flow of air to remove heat. Forced air cooling uses fans or other mechanical devices to force air to flow and speed up heat dissipation. Liquid cooling uses liquid as a cooling medium to remove heat through a pipe system. As long as the heat sink 7 can reduce the temperature of the panel 1, the specific structure of the heat sink 7 is not limited.

[0062] Due to the light-concentrating effect of the spherical cap-shaped protrusions 3, the temperature at the position corresponding to the focal point of the spherical cap-shaped protrusions 3 is high. To avoid burning out the cell units 11, a heat sink 7 is provided on the side of the panel 1 away from the glass 2, and the heat sink 7 is in contact with the position corresponding to the focal point of the spherical cap-shaped protrusions 3 on the side of the panel 1, further improving the heat dissipation effect and effectively protecting the cell units 11.

[0063] In some embodiments, the heat sink 7 can be a liquid cooling heat sink 7, which includes a cooling working medium, a cooling pipeline, a water pump, the cooling working medium flows in the cooling pipeline, the water pump is connected with the cooling pipeline, and the cooling pipeline is in contact with a position corresponding to a focal point of the spherical cap-shaped protrusion 3 on the side of the battery panel 1. The cooling pipeline is connected with a heating device, and the heating device is connected with a steam turbine. By connecting the cooling pipeline of the heat sink 7 with the heating device, the cooling working medium in the cooling pipeline is heated to a required temperature of the steam turbine, and then enters the steam turbine for utilization, thereby effectively utilizing the heat of the heat sink 7 and avoiding heat waste.

[0064] Specifically, the heating device can be a heat exchanger, the cooling working medium exchanges heat to another working medium (such as water) in the heat exchanger to generate steam, and then the steam enters the steam turbine to generate electricity. The cooling working medium can be circulated and cooled in the pipeline after heat dissipation.

[0065] Embodiment 2

[0066] A solar photovoltaic system includes the above-mentioned solar cell module.

[0067] Through the above technical solution, the solar cell module provided by the present disclosure is characterized in that a plurality of spherical cap-shaped protrusions 3 are arranged on the glass 2 of the battery panel 1, and the spherical cap-shaped protrusions 3 and the positions of the battery cells 11 are one-to-one corresponding, so that the sunlight passing through the protrusions can be focused on the battery cells 11. A reflective layer is arranged in the gap between every two adjacent spherical cap-shaped protrusions 3 of the glass 2, so that the sunlight incident in the gap between the adjacent two spherical cap-shaped protrusions, i.e. the sunlight incident in the gap between the plurality of units of the solar cell panel 1, can be reflected into the spherical cap-shaped protrusion 3 and focused on the battery cell 11 near the focal point of the spherical cap-shaped protrusion 3 for photoelectric conversion. The sunlight incident in the gap between the plurality of units of the solar cell panel 1 is effectively utilized, and the reflection loss of the incident sunlight is reduced.
