TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The metal foil comprises a material comprising steel, copper, aluminum or their alloys. The coating composition further comprises an additive. Preferred method: The powder coating method is an electrostatic-charging spray coating or a triboelectric-charging spray coating. Performing at least one curing process comprises: a first curing process and a second curing process, where the first curing process is for curing the weather-resistant coating composition to form the weather resistant layer and the second curing process is for curing the encapsulant to bond the photoelectric conversion stack film to the dielectric layer; and curing the weather resistant coating composition and the encapsulant simultaneously.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The encapsulant comprises ethylene vinyl acetate.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The dielectric layer is a polyester dielectric layer comprising a material of polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate or styrene-polyester copolymer. The barrier layer is a metal foil, metal oxide or a polymeric layer. The weather-resistant coating composition has a curing behavior that matches the curing behavior of the encapsulant. The weather resistant layer has a thickness of 10-1000 mu m. The weather-resistant coating composition comprises: many particles, each having a diameter of 10-200 mu m; and a material of polyurethane-based resins, polyurethane-acrylic based resins, Primid-based resins (RTM: Powder crosslinker), polyester-based resins, epoxies or polyester-epoxy hybrids. Preferred method: The weather resistant layer is formed from a coating composition comprising a thermosetting powder resin and a powder crosslinker, where the thermosetting powder resin comprises polyurethane-based resins, polyurethane-acrylic based resins, polyester-based resins, epoxies, or polyester-epoxy hybrids.
