Abstract

Disclosed are a photovoltaic backsheet and a photovoltaic module. The photovoltaic backsheet includes a backsheet body. The backsheet body is provided with at least one terminal lead-out hole, and the terminal lead-out hole is adapted for passage of lead-out terminals of the photovoltaic module. The terminal lead-out hole runs through two opposite sides of the backsheet body in a first direction, and a projection trajectory of the terminal lead-out hole in the first direction is composed of a plurality of line segments. The plurality of line segments include a first elliptical arc segment and a second elliptical arc segment arranged opposite to each other in a second direction, and a first circular arc segment and a second circular arc segment arranged opposite to each other in a third direction, or, a first straight line segment or a first polyline segment or another line segment and a second straight line segment or a second polyline segment or another line segment arranged opposite to each other in the third direction. The second direction intersects with the third direction. Such a terminal lead-out hole structure not only provides enough space for passage of lead-out terminals, but also improves the proper structural layout of the terminal lead-out hole on the backsheet body. In addition, an effective usable area of the backsheet body occupied by the terminal lead-out hole is reduced, thus improving the usage performance of the photovoltaic backsheet.
