TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The photoinitiator is selected to be able to initiate polymerization and crosslinking when exposed to UV and/or visible light. It is selected from 2-hydroxy-2-methyl-1-phenyl-propan-1-one, 2,4,6-trimethylbenzoyl-diphenyl-phosphineoxide, 1-hydroxy-cyclohexyl-phenyl-ketone, bis(2,6-dimethoxybenzoyl)-2,4,4-trimethyl-pentylphosphine oxide, 1-(4-(2-hydroxyethoxy)-phenyl)-2-hydroxy-2-methyl-1-propane-1-one, 2,2-dimethoxy-1,2-diphenylethan-1-one, or 2-methyl-1-(4-(methylthio)phenyl)-2-morpholinopropan-1-one.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The polymeric surface is glass, or preferably transparent plastic selected from polymethyl methacrylate (PMMA), cyclic olefin, or polycarbonate. The optical assembly comprises top glass, prism, lens, fresnel lens, or non flat optical concentrator, photovoltaic cell(s), and a back cover or sheet. The prism, lens, fresnel lens, or non flat optical concentrator comprises PMMA, polycarbonate, or cyclic olefin. The HDP is selected from acrylic polymer, aliphatic polyester, aliphatic polyurethane, or polyvinyl butyral. It is acrylic polymer including homopolymer, copolymer, and terpolymer of acrylic or methacrylic acid, ester, urethane, and/or amide. The polymer(s) is constructed of a repeating unit selected from butyl acrylate, octyl acrylate, decyl acrylate, isodecyl acrylate, tridecyl acrylate, ethyl hexyl acrylate, ethoxylated ethyl hexyl acrylate, octyl decyl acrylate, diethylene glycol 2-ethylhexyl ether acrylate, tetradecyl acrylate, cetyl acrylate, stearyl acrylate, behenyl acrylate, polyethylene glycol monoacrylate, caprolactone acrylate, or their methacrylate equivalent. The unsaturated monomer(s) is selected from acrylic acid or methacrylic acid or their derivatives including esters, urethanes and their amides, alkyl acrylate monomer, urethane acrylate monomer, polyester acrylate monomer, or unsaturated polyester. The alkyl acrylate(s) or methacrylate ester(s) is selected from lauryl methacrylate, butyl acrylate, octyl acrylate, decyl acrylate, isodecyl acrylate, tridecyl acrylate, ethyl hexyl acrylate, ethoxylated ethyl hexyl acrylate, octyl decyl acrylate, diethylene glycol 2-ethylhexyl ether acrylate, tetradecyl acrylate, cetyl acrylate, stearyl acrylate, behenyl acrylate, polyethylene glycol monoacrylate, caprolactone acrylate 2-ethyl hexyl acrylate, polyethylene glycol acrylate, or their methacrylate equivalent (A). The oligomer has greater than or equal to 2 monomers, each being selected from (A). The photo/thermocurable liquid encapsulant formulation further comprises additive(s) selected from plasticizer(s), adhesion promoting agent(s) in the form of a monomer or an oligomer, or stabilizer(s).
