Embodiment Construction

[0104] test methods

[0105] density

[0106] The density of polymers is measured according to ISO 1183-2. The preparation of the samples was carried out according to ISO 1872-2 Table 3Q (compression molding).

[0107] The melt flow rate

[0108] Melt flow rate (MFR) is determined according to ISO 1133 and expressed in g / 10 min. MFR indicates the flowability of a polymer and thus the processability of a polymer. The higher the melt flow rate, the lower the viscosity of the polymer. MFR of polypropylene 2 It was measured at a temperature of 230° C. and a load of 2.16 kg. MFR of polyethylene 2 It was measured at a temperature of 190° C. and a load of 2.16 kg.

Abstract

The invention relates to a backsheet element for a photovoltaic module comprising at least one layer, which comprises a crosslinked polymer composition, which comprises a polymer of ethylene, to a photovoltaic module comprising at least one photovoltaic element and the backsheet element of the invention and to the use of the crosslinked polymer composition for producing at least one layer of a backsheet element of the invention for a photovoltaic module.

Description

Background technique [0001] The invention relates to a backplane element, a photovoltaic module comprising at least one photovoltaic element and a backplane element according to the invention and a polymer composition for the manufacture of at least one layer of a backplane element for a photovoltaic module (PV) use. [0002] Photovoltaic modules (also known as solar cell modules) generate electrical energy from light and are used in a variety of applications well known in the art. The type of photovoltaic module can vary. Modules typically have a multilayer structure, ie a number of different layer elements with different functions. The layer elements of a photovoltaic module can vary with respect to layer materials and layer structures. The final photovoltaic module can be rigid or flexible. A rigid photovoltaic module may eg comprise a rigid glass top element, a front encapsulation layer element, at least one element of photovoltaic cells together with connectors, a rea...
