PURPOSE:To contrive to shorten the process, to form a filler sheet in a thin film at solar cell module manufacturing work by a method wherein a heat-resistant resin film evaporated to both of the surfaces thereof with vitreous moistureproof films mainly consisting of silicon oxide to be substituted for metal foil as vapor barriers is provided. CONSTITUTION:A back surface protective sheet for solar cell module is constructed of a heat-resistant and weather-resistant resin film 3, a heat-resistant resin film 5 evaporated to both the surfaces thereof with glass type moistureproof films 4, 4', and an adhesive resin layer 6. The heat-resistant and weather-resistant resin film 3 is laminated on the outside surface of the glass type moistureproof film 4', and checks generation of pin holes in the glass type moistureproof film 4' according to mechanical pressure, an impact, etc. to be applied from the outside. The heat-resistant resin film 5 checks deterioration of parts such as a solar cell element and inside wirings, etc. to be caused by invasion of moisture to the inside from the outside of a solar cell module. The adhesive resin layer 6 is arranged on the innermost surface of the protective sheet, and protects parts such as a solar cell element, inside wirings, inside of the solar cell module from a mechanical shock and pressure to be applied from the outside. |
