1. A photovoltaic array comprising:

  • A. a first outermost layer that is a single layer having a light transmittance of at least 70 percent as determined by UV/Vis spectrophotometry using ASTM E424-71 and that is silicone;

    B. two or more photovoltaic cells electrically connected to each other, each disposed on said first outermost layer; and

    C. a second outermost layer that is a single layer disposed opposite said first outermost layer, said second outermost layer comprising a (I) silicone composition and disposed on and in direct contact with said photovoltaic cells sandwiching said photovoltaic cells between said second outermost layer and said first outermost layer,wherein said (I) silicone composition comprises a linear organosilicon compound having two terminal unsaturated moieties per molecule and present in an amount of from 80 to 95 parts by weight, a branched organosilicon compound having two terminal unsaturated moieties per molecule and at least one pendant unsaturated moiety per molecule and present in an amount of from 5 to 20 as parts by weight, per 100 parts by weight of a sum of said linear organosilicon compound and said branched organosilicon compound, and an organohydrogensilicon compound having at least three silicon-bonded hydrogen atoms per molecule wherein a ratio of silicon-bonded hydrogen atoms per molecule of said organohydrogensilicon compound to a sum of unsaturated moieties per molecule of said linear organosilicon compound and branched organosilicon compound is from 1 to 1.7,wherein said first outermost layer is positioned on the top of said array and said array is free of any additional layers disposed on the top of said array, andwherein said second outermost layer is positioned on the bottom of said array and said array is free of any additional layers disposed on the bottom of said array.
