Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

Referring to Figs. 1-2, the utility model discloses a BIPV module for receiving light on a curved surface, which includes a main body of the BIPV module, and the end of the main body of the BIPV module near the light source is provided with a special-shaped curved surface.

The BIPV module receives light through the curved surface, first of all, it can reduce light reflection or change the reflection angle, and reduce the light pollution of urban buildings to a certain extent. Secondly, the setting of the curved surface is more conducive to roof drainage in areas with a lot of rainfall. Furthermore, the light-receiving area is increased through the special-shaped curved surface, which can generate electricity more efficiently and provide green energy more effectively. In addition, the BIPV module of this structure also has a variety of plane appearance effects, and the decorative effect is stronger.

The special-shaped curved surface can be regular such as a wave shape, and also can be irregular and heterogeneous.

Preferably, the main body of the BIPV module is sequentially provided with a glass support front plate 1, an encapsulating adhesive layer 2, a transparent glass middle plate 3, a thin-film solar cell power generation layer, a bus wiring layer 6, an encapsulating adhesive film 7, and tempered glass from top to bottom. The back plate 9, the upper end surface of the glass supporting front plate 1 is a special-shaped curved surface, thereby forming a curved light-receiving surface.

Wherein, the glass supporting front plate 1 is preferably set as ultra-clear transparent glass to ensure excellent light transmission. The tempered glass back panel 9 is preferably made of tempered homogeneous glass to provide sufficient strength support. And the lower end surface of the glass support front plate 1 is a plane, so that the thickness of the encapsulation adhesive layer 2 can be made uniform, so that when the thin film solar cell power generation layer and the glass support front plate 1 are bonded by the encapsulation adhesive layer 2, the Bubbles due to uneven thickness.
