Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic curtain wall technology, specifically, it relates to a photovoltaic curtain wall glass component. Background Technology

[0002] Photovoltaic curtain walls are a high-tech building technology that integrates solar panels with traditional building facades. Essentially, it acts as a building's "power-generating skin," fulfilling basic curtain wall functions such as wind and rain protection, heat insulation, and lighting, while also generating clean electricity from solar energy. This technology is a crucial pathway to achieving green building, directly transforming buildings from energy consumers into energy producers. It effectively reduces dependence on the external power grid and carbon emissions, representing the future direction of sustainable building development.

[0003] Photovoltaic (PV) curtain walls convert sunlight into electricity and typically consist of PV modules, a supporting frame, a sealed structure, and a back-mounted support. The solar cells in these modules are mainly crystalline silicon or thin-film solar cells. Currently, they are primarily constructed using laminated glass or insulated glass, with the cells encased between two layers of glass. While some systems directly attach the PV panels to the outermost glass layer, this is less common due to its aesthetic impact. Regardless of the method used, PV power generation inevitably affects light transmittance. Therefore, we designed a curtain wall with a speckled distribution of solar cells, aiming to optimize the balance between low-carbon practices and high light transmission while maintaining low cost. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a photovoltaic curtain wall glass component. The basic concept of the technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: A photovoltaic curtain wall glass assembly includes a solar cell layer and several glass layers. The solar cell layer is sandwiched between two glass layers. The solar cell layer is composed of multiple solar cells and a conductive frame. The multiple solar cells do not contact each other and are distributed in a dispersed manner within the conductive frame. The solar cells are electrically connected to the conductive frame.

[0005] Furthermore, the glass layer includes a first glass layer and a second glass layer, with a transparent elastic adhesive layer between the first glass layer and the second glass layer, and the solar cell layer is embedded in the transparent elastic adhesive layer.

[0006] Furthermore, the transparent elastic adhesive layer is an EVA layer.

[0007] Furthermore, there are three solar cells, each with a different area or shape, and the area of ​​each solar cell is no more than 1 / 16 of the area of ​​the glass layer single panel.

[0008] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0009] This utility model features a design with multiple solar cells arranged in a dispersed manner, occupying a small area within a single glass component. This effectively reduces the impact on light transmission and illumination. At the same time, the uneven distribution of the solar cells enhances the aesthetics of the architectural design, balancing beauty and practicality. It adds new possibilities to the design of photovoltaic curtain walls, boasts a high degree of modularity and low cost, optimizes the balance between low carbon emissions and lighting, and practices the concepts of building energy conservation and green building. This lays the groundwork for promoting photovoltaic curtain walls to ordinary residential buildings.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0015] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0017] like Figures 1 to 3 As shown in this embodiment, a photovoltaic curtain wall glass assembly includes a solar cell layer and several glass layers. The glass layers are two-layered: a first glass layer 3 and a second glass layer 5. A transparent elastic adhesive layer 4 separates the first glass layer 3 from the second glass layer 5, and the solar cell layer is embedded in the transparent elastic adhesive layer 4. The transparent elastic adhesive layer 4 can be made of EVA, or other commercially available materials. The solar cell 1 uses existing thin-film solar cells.

[0018] The solar cell layer consists of multiple solar cells 1 and conductive frames 2, as shown in the attached diagram. In this example, there are three solar cells 1, which are distributed in a spread-out manner within the conductive frames 2 without contacting each other. The three solar cells 1 have different areas, and their shapes are varied to highlight the differences between the cells. The solar cells 1 are electrically connected to the conductive frames 2, so that all the solar cells 1 of a single glass module can be conveyed through the conductive frames 2. Moreover, when producing a single glass module, the wiring design can be reduced; only the position of the cells needs to be adjusted, and each cell is connected to the frame.

[0019] Combined with appendix Figure 3 As shown, after multiple glass components are installed to form a curtain wall (the conductive wire frames 2 between adjacent glass components are interconnected or junction boxes are used, both of which are existing technologies), the solar cells 1 exist in the form of patches, reducing the impact on light transmission and illumination. At the same time, due to the differentiated distribution, it can highlight the aesthetics of the architectural design, taking into account both aesthetics and practicality. Here, the area of ​​each solar cell 1 is no more than 1 / 16 of the area of ​​a single glass panel, combined with the attached... Figure 1As shown in the diagram, the area of ​​the first glass layer 3 is m, and the areas of the three solar cells 1 are n1, n2, and n3, where n1≠n2≠n3≤m / 16. A smaller area ratio reduces light shading, enhances the aesthetics of the design, and also minimizes heat generation, eliminating the need for additional heat dissipation structures, thus simplifying the construction and reducing costs.

[0020] In this example Figure 3 In the application shown, four different sizes and shapes of solar cells 1 (not marked in the figure) are used to demonstrate that using different sizes of solar cells 1 can enhance the overall design aesthetics. Of course, in actual applications, the appropriate size can be selected based on design requirements.

[0021] It should be noted that the glass assembly described in this utility model is only the glass stacking part, and aims to improve the glass stacking part. The supporting frame, sealing structure, battery, inverter, and other parts involved in the curtain wall structure are all existing mature technologies, and this application does not improve them. There are many detailed descriptions in existing public information, so they will not be repeated here. In addition, this example only shows a two-layer glass illustration. In practical applications, a third or fourth layer of glass can be added, depending on the actual application.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
