Radiating solar battery back film

The utility model relates to a radiating solar battery back film. The radiating solar battery back film comprises a first weather-proof layer, a first bonding layer, a supporting body layer, a second bonding layer and a second weather-proof layer from top to bottom; at least one of the layers comprises heat conductive particles; and a graphite film is arranged on the surface of the first weather-proof layer. According to the back film, heat generated by a solar battery assembly can be immediately derived, so that the work temperature of the solar battery is reduced, the conversion efficiency of the solar battery is improved, and the service life of the solar battery is prolonged. The radiating solar battery back film is economic, practical and convenient to install.
