NOVELTY - Laminate (L1) comprises solar cell elements encapsulated within a polymer composition of a copolymer of 70-95 wt.% (based on the weight of the copolymer) ethylene and 5-30 wt.% (based on the weight of the co-polymer) of an ethylenically unsaturated carboxylic acid. The dynamic melt viscosity of the polymer is 5000-50000 mPa.s (at 120 degrees C) according to DIN 53018-1; or the melt flow index is higher than 100 g/minute (190 degrees C/2.16 kg) according to DIN 53735.    USE - As laminate for the preparation of solar cell modules (claimed).    ADVANTAGE - The E-modulus of the film made of the copolymer is 0.1-100 GPa (preferably 1-10 GPa) at 0 degrees C bottom protective laminate according to ISO 6721-1, and the transparency of the film is above 90% in the wave length of 350-1100 nm according to DIN EN 410. The present laminate can be used without cross-linking; and has excellent electrical properties, high transparency, suitable mechanical properties and satisfactory elasticity at lower temperature.    DETAILED DESCRIPTION - Laminate (L1) comprises solar cell elements encapsulated within a polymer composition of a copolymer of 70-95 wt.% (based on the weight of the copolymer) ethylene and 5-30 wt.% (based on the weight of the co-polymer) of an ethylenically unsaturated carboxylic acid of formula (I). The dynamic melt viscosity of the polymer is 5000-50000 mPa.s (at 120 degrees C) according to DIN 53018-1; or the melt flow index is higher than 100 g/minute (190 degrees C/2.16 kg) according to DIN 53735. The E-modulus of the film made of the copolymer is 0.1-100 GPa at 0 degrees C bottom protective laminate according to ISO 6721-1, and the transparency of the film is above 90% in the wave length of 350-1100 nm according to DIN EN 410.    R1=H or methyl;    R2=H or straight chain or branched 1-10C alkyl.
