Patent ID: 8097117

Claim:
A method of producing a solar module comprising: laminating a layer body comprising a first carrier, to which at least one solar cell unit is applied, and a second carrier, using at least one intermediate film based on a plasticizer-containing polyvinyl acetal positioned between said first carrier and said second carrier, wherein said laminating is performed by pressing the layer body between at least two pairs of rollers at a temperature of 50 to 150° C., wherein at least one of said first and second carriers is transparent, and wherein, after said pressing between said at least two pairs of rollers, the resultant pressed body is subjected to an increased or reduced pressure and an increased temperature, wherein said at least two pairs of rollers operate at the same or different line pressures and at the same temperature, and wherein said at least two pairs of rollers comprises a lower pair of rollers and an upper pair of rollers, and the line pressure at the front and/or rear edge of the layer body is reduced to the dead weight of the upper pair of rollers.
