Method for producing weather-resistant laminates for encapsulating solar cell systems

Abstract

The invention relates to a method for producing weather-resistant laminates (1, 1') for encapsulating solar cell systems (7). The inventive method is characterised in that at least one weather-resistant plastic layer (2, 2') is applied to a carrier material (4, 4'). The inventive coating method is advantageous in that the relatively expensive starting products, which are normally used in the form of films, can be reduced in the thickness and numbers thereof. The inventive laminate, which is produced according to said method, can be used in a plurality of ways due to the controllable adjustment of the layer thickness of the weather-resistant layer (2, 2'), in particular in connection with the finished photovoltaic modules. Said uses range from small energy plants for emergency telephones or camping cars to large-surfaced roof and faade systems and also large plants and solar power stations.

Description

technical field [0001] The invention relates to a method for the manufacture of a weather-resistant laminate for the encapsulation of solar cell systems and its use for the manufacture of photovoltaic modules (photovoltaischer modules). Background technique [0002] Photovoltaic modules are used to generate electricity from sunlight and consist of laminated materials which contain a solar cell system, for example a silicon solar cell, as a core layer. The core is encapsulated with an encapsulation material to ensure protection against mechanical and climate-induced influences. These materials can consist of one or more layers made of glass and / or plastic film and / or plastic film composites. [0003] Processes for the manufacture of weatherable film laminates for photovoltaic cell encapsulation are known from WO-A-94 / 29106, WO-A-01 / 67523 and WO-A-00 / 02257. In these modules, the solar cell system must not only be protected against mechanical damage, but also against water va...

However, these methods are energy-intensive and costly

[0005] Furthermore, due to their limited tensile strength, fluoropolymer films are only possible to manufacture in a certain minimum thickness
