[0123] The battery cell 114 is connected to the wireless charging transmitter 120. It can be understood that the battery cell 114 converts solar energy into electrical energy and sends it to the wireless charging receiver 130 through the wireless charging transmitter 120 to achieve wireless transmission of electrical energy.

[0124] The wireless charging transmitter 120 is disposed in the accommodating cavity 113, or the wireless charging transmitter 120 is disposed outside the accommodating cavity 113. In other words, the wireless charging transmitter 120 can be packaged in the accommodating cavity 113 formed by the first plate 111 and the second plate 112, or the wireless charging transmitter 120 can be installed on the outside of the packaging material (the first plate 111 and the second plate 112). The specific arrangement can be made according to actual needs.

[0125] Optionally, the photovoltaic module 110 further includes a first adhesive film and a second adhesive film. Specifically, the first adhesive film is located between the first board 111 and the battery cell 114 , and the second adhesive film is located between the battery cell 114 and the second board 112 .

[0126] like Figure 5 As shown, in some embodiments, optionally, the wireless charging transmitting device 120 is disposed on a side of the second plate 112 away from the accommodating cavity 113 .

[0127] In this embodiment, the wireless charging transmitter 120 is arranged on a side of the second plate 112 away from the accommodating cavity 113, that is, the wireless charging transmitter 120 is arranged on the outside of the accommodating cavity 113, and the wireless charging transmitter 120 is arranged close to the side of the building 200. Since the building 200 is provided with a wireless charging receiving device 130, that is, the wireless charging transmitter 120 is arranged close to the wireless charging receiving device 130, the transmission efficiency of electric energy can be improved, external interference can be reduced, and the stability and reliability of the photovoltaic device 100 and the building 200 when integrated for application can be improved.

[0128] In some embodiments, optionally, the wireless charging transmitter 120 is located between the battery sheet 114 and the second plate 112 .

[0129] In this embodiment, the wireless charging transmitter 120 is arranged between the battery cell 114 and the second plate 112, that is, the wireless charging transmitter 120 is arranged in the accommodating cavity 113, and the wireless charging transmitter 120 is arranged close to the second plate 112. Since the second plate 112 is arranged close to the building 200, that is, the wireless charging transmitter 120 is arranged close to the wireless charging receiving device 130, the transmission efficiency of electric energy can be improved, external interference can be reduced, and the stability and reliability of the photovoltaic device 100 and the building 200 when integrated for application can be improved.
