If, as in examples c) and d), a weather-resistant layer, predominantly a fluoropolymer or fluorocopolymer, is used, a film uniform in its chemical constitution is produced. If, however, chemically different polymers are used, as stated in examples a) and b), it is also possible to use polymer mixtures for the weather-resistant layer 2, 2 '.

- an inorganic oxide layer preferably a silicon oxide layer, deposited from the vapor phase.
- a solvent halogen-free organic solvents are used for environmental and disposal reasons.
- the solution or dispersion may further comprise dyes.
- dyes During coating, it has also proven to be advantageous to use dispersions, since when preparing a dispersion, the solvent content can be substantially reduced.
- a fluoropolymer is dissolved at 40-100 ° C. and a stirring speed of at least 2800 rpm by means of an intensive stirrer or dissolver under reflux in 2-butanone.
- Diverse fillers or dyes, such as titanium dioxide or carbon black can be added to the solution up to a proportion of 35%, based on the fluoropolymer used, so that a dispersion is formed. This is applied to the carrier material 4, 4 ', for example a pre-treated PET film, via the application devices 11.
- the layer thickness of the weather-resistant layer 2, 2 ' is controlled, which is for example in a range of 5 to 50 microns.
- the thus coated material 4, 4 ' is then fed via the deflection rollers 9a to a dryer 12, in which the solvent used is evaporated at temperatures between 80 ° and 180 ° C. Exhaust air and temperature settings in the dryer are selected so that a bubble-free, dry coating is produced. The residual solvent content of 0.3-0.6% is used as a criterion for accurate temperature adjustment.
- the carrier material 4, 4 'provided with the layer 2, 2' is further fed to the storage roll 13 via a deflection roller 9b and wound up on this.
- the carrier material 4, 4 'provided on one side with the weather-resistant layer 2, 2' can now be coated on the still uncoated surface side with the adhesion layer 5, 5 1 .

- a further encapsulating material layer 1 is removed and fed to the solar cell system 7.
- the material webs drawn off from the storage rolls 9 and 9a are each fed to a heating station 14 or 14a in which the encapsulation materials 1, 1 'are heated at least to the softening temperature of the sealing layer 6, 6'. This ensures the formation of a bond between the layers 1, 1 'on the one hand and the solar cell system 7 on the other hand in the nip of the calendering station 15.
- the pre-bond is fed to a heating station 16.
- the composite 17 for a photovoltaic module can be stored on the storage roll 9b and deducted accordingly.
- the production is economical in terms of process, since the thickness of the weather-resistant layer 2, Z 'can be reduced and thus the proportion of relatively expensive fluoropolymers can be reduced.
