NOVELTY - Use of a radiation-curable resin composition comprising (a) at least one isocyanate-functional compound exhibiting at least one radiation-curable group, preferably vinyl-, propenyl-, allyl-, vinyl ether-, maleyl-, fumaryl-, maleimide-, dicyclopentadienyl-, acrylamide- or (meth)acrylate group, and (b) at least one polyol, for producing solar laminates, is claimed.    USE - The radiation-curable resin composition is useful for producing solar laminates (claimed).    ADVANTAGE - The composition produces the solar laminates in a simple manner, exhibits good adhesion in all regions between different layers of the solar laminates, and can be processed at room temperature, and thus it prevents heating during lamination step in the production of the solar laminate, which saves thermal energy, and prevents stress on the solar modules during production by strong heating.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) producing the solar laminate, which comprises at least one solar cell having a front side, a back side, back contacts connected with the front and the back side, a glass sheet and a backsheet, comprising (a) applying the above radiation-curable resin composition on the backsheet and the glass sheet of the solar module, (b) curing obtained coating by actinic radiation, (c) contacting the front side of the solar cell with the resin layer formed on the glass sheet, (d) contacting the back side of the solar cell with the resin layer formed on the backsheet, (e) carrying out the back contacts of the solar cell through the backsheet, (f) introducing the obtained layer composite into a vacuum laminator for removing entrapped air, and (g) partially curing the remaining isocyanate- and hydroxy functionalities of the resin composition in the vacuum laminator under reduced atmospheric pressure, for effective bonding of the front- and back side of the solar element, and encapsulation of the solar cell, or (a1) applying the above radiation-curable resin composition on the backsheet of the solar module, (b1) curing obtained coating by actinic radiation, (c1) contacting the back side of the solar cell with the resin layer formed on the backsheet, (d1) carrying out the back contacts of the solar cell through the backsheet, (e1) applying the radiation-curable resin composition on the front side of solar laminate obtained in step (d1), (f1) contacting the front side of the solar cell with a glass sheet, (g1) introducing obtained layer composite into a vacuum laminator, (h1) partially curing the remaining isocyanate- and hydroxy functionalities of the resin composition in the vacuum laminator under reduced atmospheric pressure, (i1) curing the remaining double bonds of the resin composition by actinic radiation through the front glass sheet primed with radically reactive groups, after discharging from the laminator, and (j1) bonding the glass sheet with the resin matrix and encapsulating the solar cell (when the solar laminate comprises at least one solar cell having a front side, a back side, back contacts connected with the front and the back side, and a backsheet), or (a2) applying an adhesive on the backsheet and/or the back side of the solar cell, (b2) contacting and bonding the back side of the solar cell with the backsheet, (c2) carrying out the back contacts of the solar cell through the backsheet, (d2) applying the above radiation-curable resin composition on the front side of solar laminate obtained in step (c2), (e2) curing the resin composition by actinic radiation, (f2) optionally protecting flat encapsulated cell obtained in step (e2) with a further front sheet or glass sheet in vacuum lamination process, and (g2) optionally protecting the flat encapsulated cell obtained in step (e2) by at least one further lacquer coating; and    (2) the solar laminate produced by the above method, comprising the above resin composition (when the solar laminate comprises at least one solar cell having a front side, a back side, back contacts connected with the front and the back side, and a backsheet).
