The invention relates to the use of plasticized, polyvinyl acetal-based films which comprise more than 10 ppm metal ions selected from the group including alkaline earth metals, zinc and aluminum and less than 150 ppm alkali metal ions, for producing photovoltaic modules. The films preferably have an electrical volume resistance of more than 1E11 ohm*cm in an ambient environment of 85% RH/23°C. The photovoltaic modules can be used as façade components, roof surfaces, conservatory covers, noise protection walls, balcony or breastwork elements or as components of window surfaces. |
