摘要： A photovoltaic curtain wall and a method for manufacturing the photovoltaic curtain wall are provided. The photovoltaic curtain wall includes a first cover plate, a cell string, and a second cover plate stacked sequentially in a first direction; and an encapsulation film including a first adhesive film and a second adhesive film, the first adhesive film is attached to the first cover plate, and the second adhesive film is attached to the second cover plate. The second cover plate has a thickness greater than or equal to an equivalent thickness, and the first cover plate has a thickness less than the thickness of the second cover plate; and the equivalent thickness is a thickness of a target cover plate that undergoes a preset bending deformation in response to a preset load, and the target cover plate and the second cover plate is made of a same material.

摘要： The present disclosure relates to a UV-resistant photovoltaic module. The photovoltaic module includes a cell layer, a back sheet layer, a UV barrier layer, and a connection layer. The back sheet layer is arranged on a backlight side of the cell layer. The UV barrier layer is arranged on a light-facing side of the cell layer, and the UV barrier layer is made of a flexible material. The connection layer is located between the cell layer and the back sheet layer and between the cell layer and the UV barrier layer. The UV barrier layer includes a UV absorbent, and the UV absorbent is one or more of 2-(2'-hydroxy-3',5'-di-tert-phenyl)-5-chloro benzotriazole, 2-(2'-hydroxy-5'-methylphenyl)benzotriazole, 2-hydroxy-4-n-octoxyl benzophenone, and 2-hydroxy-4-methoxy benzophenone.

摘要： The embodiments of the present application relate to the technical field of solar cells, in particular to a photovoltaic module and a method for folding a photovoltaic module, and the photovoltaic module includes multiple cell sheets arranged in an array, where each of the multiple rows of cell sheets is arranged at intervals along a first direction, each of the multiple columns of cell sheets is arranged at intervals along a second direction, and each of the multiple cell sheets has a first surface and a second surface. The photovoltaic module further includes a first flexible cover layer located on a side of the first surface of each of the multiple cell sheets, and a second flexible cover layer located on a side of the second surface of each of the multiple cell sheets. The photovoltaic module is configured to be folded along a gap between two adjacent rows in the multiple rows of cell sheets or along a gap between two adjacent columns in the multiple rows of cell sheets with the folding angle of 0 degree to 180 degrees between two adjacent columns of cell sheet. The embodiments of the present application are beneficial for improving the folding performance of the photovoltaic module.
