TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Processes: The method includes embossing greater than or equal to 1 surface of green silicone rubber sheet of silicone rubber composition and laminating embossed silicone rubber sheet to surface of transparent panel such that the embossed surface of the silicone rubber sheet may be disposed remote from the transparent panel. The method includes embossing greater than or equal to 1 surface of green silicone rubber sheet of silicone rubber composition and laminating embossed silicone rubber sheet to surface of 2nd panel or backsheet such that the embossed surface of the silicone rubber sheet may be disposed remote from the 2nd panel or backsheet. Both surfaces of green silicone rubber sheet are embossed. Embossing step is carried out by pressing 2 sheet-form templates having a patterned surface against opposite surfaces of the green silicone rubber sheet. The method includes performing steps of separating 1 template from either 1 surface of the green silicone rubber sheet, laminating the embossed surface of the green silicone rubber sheet to the transparent panel, 2nd panel or backsheet so that recesses of the emboss structure may not collapse, and then separating the other template from the opposite surface of the green silicone rubber sheet, prior to mating process. Step of providing 1st laminate includes laminating the green silicone rubber sheet of silicone rubber composition to 1 surface of the transparent panel and embossing the surface of the silicone rubber sheet laminated to the transparent panel. Step of providing 2nd laminate includes laminating the green silicone rubber sheet of silicone rubber composition to 1 surface of the 2nd panel or backsheet and embossing the surface of the silicone rubber sheet laminated to the 2nd panel or backsheet. Lamination steps are performed by using a laminator comprising a pressure roller in vacuum. Embossing step includes using a roll having a patterned surface as the template and pressing the roll against the green silicone rubber sheet. Mating process includes resting the solar cell matrix on the silicone rubber sheet of the 1st or 2nd laminate, mating the 1st and 2nd laminates with the silicone rubber sheets inside, and heating and compressing the 1st and 2nd laminates in vacuum to cure the silicone rubber sheets for establishing a seal around the solar cell matrix. Preferred Conditions: Heating temperature in mating process is 70-150 degrees C.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: Component (C) is combination of organo-hydrogenpolysiloxane with hydrosilylation catalyst, or organic peroxide.    TECHNOLOGY FOCUS - POLYMERS - Preferred Parameters: Green silicone rubber sheet has thickness of 0.3-2 mm. Preferred Compositions: The backsheet is a composite sheet consisting of polyethylene terephthalate resin film coated on both surfaces with vinyl fluoride resin films. Silicone rubber composition comprises 100 pts. wt. organopolysiloxane (A) which contains greater than or equal to 2 alkenyl groups per molecule, has a degree of polymerization of greater than or equal to 100, and is represented by formula R1aSiO(4-a)/2 (I), 10-150 pts. wt. reinforcing silica (B) having specific surface area of greater than or equal to 50 m2/g, and curing agent (C) which is present at sufficient amount to cure component (A).R1=optionally substituted monovalent hydrocarbon group; anda=1.95-2.05.
