Abstract:
1. A solar cell pre-laminate assembly comprising: (i) a solar cell component comprising one or a plurality of solar cells and having a light-receiving side and a back side, (ii) a first encapsulant layer positioned next to the light-receiving side of the solar cell component consisting essentially of an ionomeric copolymer of ethylene and about 15 to about 25 wt % of an alpha, beta-ethylenically unsaturated carboxylic acid selected from the group consisting of acrylic acid, methacrylic acid, or a mixture thereof, based on the total weight of the copolymer, wherein the carboxylic acid is neutralized to a level of about 10 to 100 mol %, with one or more metal ions, based on the total number of moles of carboxylate groups in the copolymer, and (iii) a second encapsulant layer positioned next to the back side of the solar cell component consisting essentially of a non-ionomeric polymer selected from the group consisting of poly(ethylene-co-vinyl acetate) and plasticized poly(vinyl butyral), further comprising a fluoropolymer incident layer serving as an outer layer at the light-receiving side of the assembly, and a backing layer serving as an outer layer at the back side of the assembly.
