Abstract: The invention relates to a method of producing a solar module by laminating a layer body consisting of a first carrier, to which at least one solar cell unit is applied, and a second carrier by at least one intermediate film based on a plasticizer-containing polyvinyl acetal by guiding the layer body between at least one pair of rollers at a temperature of 50 to 150° C.

Abstract: The invention relates to the use of plasticizer-containing films based on polyvinyl acetal and having a high alkali titre for the production of photovoltaic modules.

Abstract: Plasticized films suitable as an intermediate layer in laminated safety glass and based on partially acetalized polyvinyl alcohols, in particular PVB, have not only the required excellent adhesion to glass but also undesired self-adhesion (susceptibility to blocking). Amounts of from 0.001 to 0.1% by weight of a pentaerythritol ester are proposed for use as an additive which reduces self-adhesion. This additive does not alter the adhesion of the film to glass. The invention is used for producing films for the production of laminated safety glass. The need to cool the films for stacking or wind-up is substantially eliminated.

Abstract: Solar modules, with the properties of laminated safety glass, comprising a laminate containing a) a glass pane b) at least one solar cell unit that is located between two PVB-based films, and c) a rear covering and at least one of the PVB-based films has a tensile strength of at least 16 N/mm2, are suitable for use as a facade component, roof surface, winter garden covering, soundproofing wall, or as a component of windows.
