[0026] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0027] This embodiment proposes a curtain wall photovoltaic device, which includes a first photovoltaic component and a second photovoltaic component, and the first photovoltaic component and the second photovoltaic component are movably arranged relative to each other. The first photovoltaic component and the second photovoltaic component both have light-transmitting portions 10 and cells 2 arranged at intervals. The light-transmitting portions on the first photovoltaic component and the light-transmitting portions 10 on the second photovoltaic component are overlapped or staggered by the relative movement between the first photovoltaic component and the second photovoltaic component.

[0028] Specifically, in this embodiment, the curtain wall photovoltaic device is composed of a first photovoltaic component and a second photovoltaic component. Among them, the first photovoltaic component and the second photovoltaic component can both be provided with a slidable mounting structure, or one of them can be fixed and the other can slide. This embodiment is explained by taking the first photovoltaic component as a fixed part and the second photovoltaic component as a movable part as an example, that is, the relative position between the first photovoltaic component and the second photovoltaic component can be changed by moving the second photovoltaic component. A plurality of battery cells 2 are provided in the first photovoltaic component and the second photovoltaic component, and there are intervals between the battery cells 2, and the interval area is the light-transmitting portion 10, such as Figure 1 As shown. The cell 2 can be a rectangular shape with any aspect ratio. The light-transmitting portion 10 in the first photovoltaic module and the second photovoltaic module has the same size. In this way, during the movement of the second photovoltaic module, the light-transmitting portion 10 on the first photovoltaic module and the second photovoltaic module can coincide with each other to meet the best light transmission requirements, such as Figure 2 and Figure 3At the same time, the cells 2 and the light-transmitting parts 10 on the first photovoltaic module and the second photovoltaic module can also be overlapped to meet the best shading requirements, such as Figure 4 and Figure 5 shown.

[0029] Furthermore, in this embodiment, the structures of the first photovoltaic assembly and the second photovoltaic assembly are substantially the same. From the appearance, it is equivalent to the first photovoltaic assembly and the second photovoltaic assembly being a symmetrical structure rotated 180 degrees, such as Figure 6 As shown. The first photovoltaic module and the second photovoltaic module both include a frame 1, a cell 2, a glass 3, a packaging film 4 and a back plate 5, a plurality of cells 2 are mounted between the glass 3 and the back plate 5 through the packaging film 4, the glass 3 and the back plate 5 are fixed by the frame 1, and the cells 2 and the light-transmitting portion 10 are arranged at intervals.

[0030] For ease of use, in actual application, the first photovoltaic assembly and the second photovoltaic assembly are placed outdoors and indoors respectively, and a limit baffle 6 is fixed on the side of the first photovoltaic assembly located outdoors. The width of the limit baffle 6 can be slightly larger than the width of the battery cell 2 to ensure the light transmission or light shielding effect at the edge of the device. The limit baffle 6 can be used as a ruler for the movement of the second photovoltaic assembly. Figure 3 As shown, when the right side of the second photovoltaic assembly is flush with the right side of the limit baffle 6, it can be ensured that the light-transmitting parts 10 of the first photovoltaic assembly and the second photovoltaic assembly are completely overlapped, and the entire device is light-transmitting. Figure 5 As shown, when the right side of the second photovoltaic assembly is flush with the left side of the limiting baffle 6, it can ensure that the cell sheets 2 and the light-transmitting parts 10 of the first photovoltaic assembly and the second photovoltaic assembly overlap, and the entire device is shielded from light.

[0031] Furthermore, the curtain wall photovoltaic device proposed in this embodiment further includes a mounting groove 8 for mounting the first photovoltaic component and the second photovoltaic component. Figure 6 As shown, the first photovoltaic component is directly fixed on the mounting groove 8 and cannot be moved. The second photovoltaic component is configured as a slidable structure and can slide horizontally on the mounting groove 8 to achieve a change in relative position with the first photovoltaic component.

[0032] Specifically, in this embodiment, a raised slide rail is provided on the mounting groove 8. Correspondingly, a slide groove is provided on the frame 1 of the second photovoltaic module, and the slide groove can be connected with the slide rail. In this way, the second photovoltaic module can slide horizontally on the mounting groove 8 through the cooperation between the slide groove and the slide rail. At the same time, in order to facilitate the control of the sliding of the second photovoltaic module, a control rod 7 can be provided on the second photovoltaic module. The control rod 7 can be designed to be a handle or a metal rod or other easy-to-operate shape, so that the sliding direction of the second photovoltaic module can be controlled by hand or machine.

[0033] In addition, in this embodiment, the second photovoltaic module can also be replaced by other plates 9, such as Figure 7 As shown. Specifically, light-transmitting and light-impermeable areas can be set in the plate 9. The light-transmitting and light-impermeable areas of the plate 9 can cooperate with the cell sheet 2 of the first photovoltaic module to achieve the same light-transmitting adjustment effect. In this way, the plate 9 can also be directly fixed on the first photovoltaic module, and a groove is directly opened on the frame 1 of the first photovoltaic module, and then the plate 9 is placed in the groove, which can save the installation space of the device.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
