The utility model discloses a coated FPC structure solar cell backboard film. The backboard film comprises an ETFE film, a first nylon composite film, an aluminum foil reflection film, a foaming rubber layer, a second nylon composite film, an EVA film, a modified polyolefin film, a nylon film and a polymer alloy film. The solar cell back film comprises an ETFE film, and a foamed rubber layer, theETFE membrane has high stain resistance; the solar cell backboard has the advantages of being simple in structure and easy to clean, rainwater can remove dust and dirt on the surface of a film, the situation that film corrosion is accelerated due to the fact that dust and dirt adhere to the surface of the film is reduced, the foamed rubber layer is high in flexibility, when an object impacts the film, a large part of impact force can be absorbed under the action of the foamed rubber layer, and the solar cell backboard is protected conveniently; the first nylon composite film and the second nylon composite film can gre
