TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The white pigment is at least one of zirconium oxide, barium sulfate, titanium dioxide, silicon dioxide, calcium carbonate, zinc sulfate and lithopone.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The ternary ethylene propylene rubber film layer further comprises an auxiliary agent, which is at least one of 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane, 1,1-bis-tertiary butylperoxy)-3,3,5-trimethyl cyclohexane, 1,1-bis(tert-butylperoxy)cyclohexane, tert-butylperoxy-2-ethylhexanoate, dicumyl peroxide, o,o-tertiary pentyl-o-(2-ethylhexyl)-mono-peroxycarbonate and 2,5-dimethyl-2,5-di(benzoylperoxy)-hexane. The content of the auxiliary agent is 0.1-2 wt.% of the total weight of the ternary ethylene propylene rubber film layer. The stabilizing agent is diphenyl ketone ultraviolet absorbent and/or benzotriazole ultraviolet absorbent. The adhesive is at least one of a double-component polyurethane adhesive, a single-component polyurethane adhesive, polyacrylate adhesives and polyester adhesives.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The ratio of the thickness of the first resin layer, water vapor barrier layer and second resin layer is 2-30:1:2-30. The solar cell back panel comprises the first resin layer and the second resin layer, where at least one is ternary ethylene propylene rubber film layer. The ternary ethylene propylene rubber film layer is an ethylene-propylene-vinylnorbornene copolymer. The aluminum oxide-polyester film comprises an aluminum oxide film layer and a polyester film layer. The silicon dioxide-polyester film comprises a silicon dioxide film layer and a polyester film layer, and in the solar cell back panel, the aluminum oxide film layer or the silicon dioxide film layer is in contact with the second resin layer. The thickness ratio of the aluminum oxide film layer and the polyester film layer is 1:50-5000 in the aluminum oxide-polyester film, and thickness ratio of the silicon dioxide film layer and the polyester film layer is 1:50-5000 in the silicon dioxide-polyester film. The polyester film layer is a film layer formed by polyethylene glycol terephthalate. The first resin layer and the second resin layer further comprises additives. The content of additives in the first resin layer is 0.1-30 wt.% of the total weight of the first resin layer and the content of the additives in the second resin layer is 0.1-25 wt.% of the total weight of the second resin layer, where the additives are white pigments and/or stabilizing agents. The adhesive layers are also included between the first resin layer and the water vapor barrier layer, and between the second resin layer and the water vapor barrier layer, where the adhesive layers are 0.01-100 mu m thick.
