The invention provides a dual-initiated and fast cross-linked EVA (ethylene/vinyl acetate copolymer) film for the encapsulation of solar modules, which greatly enhances the speed of the encapsulation. The EVA film is mainly prepared from the following raw materials: 100 parts by mass of ethylene/vinyl acetate copolymer, 0.01 to 1.5 parts by mass of a free-radical photoinitiator, 0.01 to 1.5 parts by mass of a free-radical thermal initiator, 0.5 to 10 parts by mass of an auxiliary cross-linking agent, 0.1 to 5 parts by mass of a tackifier and 0.01 to 5 parts by mass of a light stabilizer. The present invention adds photothermal dual-initiated free-radical initiators and the auxiliary cross-linking agent of multi-functional acrylates or methacrylates to the EVA and use a thermal-UV dual curing process to prepare the solar module. The curing time is shorten to 5 to 10 min and the yield is high; meanwhile, the EVA film has advantages of uniform curing, high crosslink density, high bonding strength between the film and glass, and good anti-aging property.

A method for manufacturing a pressure-sensitive self-adhering adhesive is based on an alkoxylated silane-containing polymer, to which is added at least one tackifying resin compatible with the alkoxylated, silane-containing polymer, and at least one catalyst (K). To overcome various disadvantages of the prior art, such as a too-slow or excessively violent reaction of the alkoxyl groups, and the need for an additional supplying of water, the alkoxylated silane-containing polymer is crosslinked using a catalyst (K) that comprises a Lewis acid-base adduct, wherein the Lewis acid (LS) is a reaction-inhibited cation at least in the temperature range below 60° C., and the Lewis base (LB) is an anion of a very strong acid. In a preferred embodiment the Lewis acid (LS) is an organyl-group-containing (AG) halogen-onium cation, and the Lewis base (LB) is the anion of a superacid.
