摘要: A back panel of a solar cell and a method for manufacturing the same are provided. The back panel includes a prepreg and a fluorine-containing polymer layer, and the fluorine-containing polymer layer is formed on the prepreg. The prepreg is formed by immersing a fiber substrate into a resin composition. Based on a total weight of the resin composition being 100 PHR (parts per hundred resin), the resin composition includes: 5 PHR to 70 PHR of a first epoxy resin, 1 PHR to 20 PHR of a hardener, and 0.01 PHR to 10 PHR of an accelerant. The first epoxy resin contains phosphorus atoms, and an amount of the phosphorus atoms in the first epoxy resin ranges from 0.1 wt % to 5 wt %.

摘要: A filler disposition film that can use a commercially procurable filler material having good particle diameter uniformity, enables high positional precision of the filler disposition, can support even an increase in the surface area, and has a prescribed filler regularly disposed in a long resin film. Moreover, the rate of consistency of disposition of the filler in the filler disposition film in rectangular areas of a prescribed size having a length of 1000 times or more the average particle diameter of the prescribed filler, and a width of 0.2 mm or greater is 90% or greater. Such a rectangular area has a long-side direction that is substantially parallel to the long-side direction of the filler disposition film, and a widthwise direction that is substantially parallel to a short-side direction of the filler disposition film. The average particle diameter of the regularly disposed filler is from 0.4 μm to 100 μm.
