The solar module useful in solar power plant, comprises a layer made of alpha -olefin-vinyl acetate-copolymers, a glass substrate (A) with a front and a rear side, a transparent polymer layer (B) applied on the rear side of the glass substrate, solar cells (C) introduced on the polymer layer, a further transparent polymer layer (D) applied on the solar cells, a protective layer (E), a junction box and a connection terminal, and aluminum profile-frames (F). The front side of the substrate is a turned side in the fabricated solar module for sun. The solar cells are embedded into the polymer layers. The solar module useful in solar power plant, comprises a layer made of alpha -olefin-vinyl acetate-copolymers, a glass substrate (A) with a front and a rear side, a transparent polymer layer (B) applied on the rear side of the glass substrate, solar cells (C) introduced on the polymer layer, a further transparent polymer layer (D) applied on the solar cells, a protective layer (E), a junction box and a connection terminal, and aluminum profile-frames (F). The front side of the substrate is a turned side in the fabricated solar module for sun. The solar cells are embedded into the polymer layers. The transparent polymer layers are made of alpha -olefin-vinyl acetate-copolymers. The alpha -olefin-vinyl acetate-copolymer is produced with a pressure of 100-700 bar after a solution polymerization process, is in uncrosslinked form and has vinyl acetate content of >= 80 wt.% related to the total weight of the alpha -olefin-vinyl acetate-copolymers, a melt flow index (MFI)-value of 2-6 g/10 minutes measured according to ISO 1133 at 190[deg] C and a weight of 21.1 N and a Mooney viscosity of 4-35 Mooney-units according to DIN 53523 ML 1 + 4 at 100[deg] C. The number average molecular weight of the alpha -olefin-vinyl acetate-copolymers is 5000-200000 g/mol determined by gel-permeation chromatography. The layer has no ageing protecting agent and/or no bonding agent. |
