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 %.

Abstract: A plastic wrap is provided. The plastic wrap is formed from a biodegradable material. The biodegradable material includes a biodegradable polymer and a chain extender. The biodegradable polymer includes polybutylene adipate terephthalate (PBAT). Based on a total weight of the plastic wrap being 100 phr, an amount of the PBAT is higher than 85 phr. The chain extender is selected from the group consisting of: an epoxy functional compound, a dianhydride compound, diisocyanate, phosphite, dioxazoline, and any combination thereof.

Abstract: A board-to-board fixture includes rivet sleeve having hollow tube with perforation inside, stop flange formed on the bottom side of hollow tube, operating space formed in the stop flange to communicate with perforation and expansion portion formed on the top side of hollow tube, and rivet rod having head, tapered impact portion formed on the bottom side of head, deformation portion downwardly protruded from the bottom side of impact portion for pressing against the top side of preset rivet gun socket at the operating space to generate deformation, increasing bump extending downward from the outer edge of the bottom side of deformation portion, breaking portion with a smaller round diameter formed on the center of the bottom side of deformation portion and shank downwardly extending from the bottom side of breaking portion to penetrate the perforation and the operating space through the expansion portion of rivet sleeve.

Abstract: A keyboard illuminating device for a portable computer includes a battery module and an illuminating module. The battery module can supply power to the portable computer and includes a housing. The illuminating module is disposed on the battery module and is powered by the battery module to illuminate a keyboard of the portable computer. The illuminating module hides in the battery module when the keyboard illuminating device is in a first status, and the illuminating module protrudes from a surface of the battery module when the keyboard illuminating device is in a second status.
