Abstract

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 %.
