[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] The following describes a building according to an embodiment of the present invention with reference to the accompanying drawings. The building according to the embodiment of the present invention includes a body and a photovoltaic device 1 .

[0020] like Figure 1-Figure 3 As shown, the photovoltaic device 1 according to the embodiment of the present invention includes a frame 10, a photovoltaic assembly 20, an LED assembly 30 and a driving member (not shown in the figure).

[0021] The frame 10 is rotatably arranged on the body. The photovoltaic assembly 20 is arranged on the frame 10, and the LED assembly 30 is arranged on the frame 10. The driving member is connected to the frame 10 so as to drive the frame 10 to rotate. The photovoltaic assembly 20 is located on a first side of the rotation axis of the frame 10, and the LED assembly 30 is located on a second side of the rotation axis of the frame 10, and the first side is opposite to the second side in a first preset direction.

[0022] During the day, the photovoltaic assembly 20 can be made to face the sun so that sunlight shines on the photovoltaic assembly 20, thereby generating electricity using the photovoltaic assembly 20. During the day, the first side can be the south side, and the second side can be the north side.

[0023] Since the photovoltaic assembly 20 and the LED assembly 30 are located on opposite sides of the rotation axis of the frame 10, the frame 10 can be rotated 90 degrees to 270 degrees in a clockwise or counterclockwise direction at night, so as to illuminate the building with the LED assembly 30. At night, the first side can be the north side, and the second side can be the south side.

[0024] The photovoltaic device 1 according to the embodiment of the present invention can generate electricity during the day and illuminate the building at night by disposing the photovoltaic components 20 and the LED components 30 on opposite sides of the rotation axis of the frame 10 .

[0025] Furthermore, by installing the photovoltaic device 1 on the building, not only can the building's exterior decoration materials be saved, but also the building's energy consumption can be reduced by generating electrical energy.

[0026] Therefore, the photovoltaic device 1 according to the embodiment of the present invention has the advantages of diverse functions, etc. By using the photovoltaic device 1, it is possible to save the exterior decoration materials of the building, reduce the energy consumption of the building, and illuminate and beautify the building at night.

[0027] The building according to the embodiment of the present invention has the advantages of not requiring additional lighting devices, using less exterior decoration materials, and having low energy consumption, etc. by installing the photovoltaic device 1.

[0029] The first preset direction is Figure 1 As shown by arrow A in FIG. Figure 1 As shown by arrow B in FIG. For example, the first preset direction may be a north-south direction, and the second preset direction may be an up-down direction.

[0030] like Figure 1 As shown, the frame 10 includes a first frame 110 and a second frame 120, and the first frame 110 and the second frame 120 are arranged spaced apart along the second preset direction. The first end of the photovoltaic component 20 is arranged on the first frame 110, the first end of the LED component 30 is arranged on the first frame 110, the second end of the photovoltaic component 20 is arranged on the second frame 120, and the second end of the LED component 30 is arranged on the second frame 120.

[0031] Preferably, the first frame 110 may be an aluminum alloy frame, and the second frame 120 may also be an aluminum alloy frame.

[0032] The first frame 110 has a first slot and a second slot, and the second frame 120 has a third slot and a fourth slot. The first end of the photovoltaic component 20 is engaged in the first slot, the first end of the LED component 30 is engaged in the second slot, the second end of the photovoltaic component 20 is engaged in the third slot, and the second end of the LED component 30 is engaged in the fourth slot.

[0033] like Figure 1 As shown, in one embodiment of the present invention, the photovoltaic device 1 further includes a first embedded part 410 , a second embedded part 420 , a first rotating shaft 510 and a second rotating shaft 520 .

[0034] The first embedded part 410 and the second embedded part 420 are arranged at intervals along the second preset direction, the first embedded part 410 is arranged in the first decorative surface layer 2, and the second embedded part 420 is arranged in the second decorative surface layer 3.

[0037] By rotating the frame 10, the photovoltaic assembly 20 can track the trajectory of the sun, so that the photovoltaic assembly 20 is always oriented to the direction where the maximum power generation can be obtained. Specifically, the rotation axis of the frame 10, the rotation axis of the first rotating shaft 510, and the rotation axis of the second rotating shaft 520 can coincide with each other.

The electric latch at the disengaged position is disengaged from the lock hole, and the electric latch at the locked position is fitted into the lock hole.

[0039] By providing the electric latch and the lock hole, after rotating the frame 10, the frame 10 can be locked using the electric latch fitted in the lock hole, so as to prevent the frame 10 (photovoltaic device 1) from shaking due to factors such as wind, thereby improving the stability of the frame 10 (photovoltaic device 1).

[0040] Preferably, there are multiple lock holes, and the multiple lock holes are located on a first circumference, and the center of the first circumference is located on the rotation axis of the frame 10.

[0042] The first substrate 210 has a first surface and a second surface opposite to each other in the first preset direction. The CIGS film layer is disposed on one of the first surface and the second surface.

[0043] The first adhesive layer 220 is disposed on the CIGS film layer, and the second adhesive layer 230 is disposed on the other of the first surface and the second surface. The first glass plate 240 is disposed on the first adhesive layer 220, and the second glass plate 250 is disposed on the second adhesive layer 230.

[0044] By providing the photovoltaic module 20 with the CIGS film layer, the unique anti-shading technology of CIGS can be used to generate more green electricity to meet the needs of the building and greatly reduce the energy consumption of the building.

[0045] The DC power generated by the photovoltaic module 20 is converted into 0.4kV AC power through the grid-connected inverter, and connected to the electric control system through the grid-connected box, and is preferentially supplied to the photovoltaic device 1 and the building itself, and the excess power is input into the grid. When the power generated on rainy days is not enough to supply the building, it is supplemented by the public grid.

[0046] Preferably, the first adhesive layer 220 and the second adhesive layer 230 can both be made of PVB, and the first glass plate 240 and the second glass plate 250 can both be semi-tempered glass plates, which are used to ensure that the photovoltaic module 20 meets the parameters or standards required for use as a building material.

[0047] In a specific example of the present invention, the photovoltaic module 20 can be manufactured by the following method: clean a substrate glass (first substrate 210) with a thickness of 3 mm, deposit a CIGS power generation layer on the substrate glass to form the CIGS film layer, lay a PVB film with a thickness of about 1 mm on the substrate glass and the CIGS film layer, and place it between two upper and lower semi-tempered glass substrates with a thickness of 5 mm, and perform high temperature and vacuum treatment in an autoclave or a laminator, so that the substrate glass coated with the CIGS film layer is combined with the semi-tempered glass substrate to obtain the photovoltaic module 20.

[0048] Preferably, the CIGS film layer structure is, from bottom to top, metal Mo back electrode, CIGS film layer, CdS buffer layer, and ZnO window layer.

[0049] like Figure 1 and Figure 3As shown, the LED assembly 30 includes a laminated tempered glass layer 310 and an LED matrix 320. The LED matrix 320 is located between the photovoltaic assembly 20 and the laminated tempered glass layer 310 in the first preset direction. Thus, the laminated tempered glass layer 310 can be used to protect the LED matrix 320, thereby preventing the LED matrix 320 from being damaged.

[0050] The LED dot matrix 320 may be spaced apart from the laminated tempered glass layer 310, and the LED dot matrix 320 may also contact the laminated tempered glass layer 310. The first end of the laminated tempered glass layer 310 is engaged in the second slot, and the second end of the laminated tempered glass layer 310 is engaged in the fourth slot.

[0051] In a specific example of the present invention, the laminated tempered glass layer 310 can be manufactured by the following method: two pieces of tempered glass with a thickness of about 6 mm are cleaned, a PVB film with a thickness of about 1 mm is laid between the two pieces of tempered glass, and high-temperature and vacuum treatment is performed in an autoclave or a laminator so that the two pieces of tempered glass and the PVB film are combined into one, so as to obtain the laminated tempered glass layer 310.
