Abstract: A method for sealing the edges of photovoltaic modules, including the steps of i) providing a photovoltaic module by applying at least one photovoltaic laminate to a carrier; ii) treating the photovoltaic module produced in step i) along the edge region of the photovoltaic laminate by means of a plasma pretreatment or by flame application by means of a gas flame, such that both the edge region of the photovoltaic laminate and, at least partially, the carrier is detected by the plasma pretreatment or the flame application; and iii) applying a sealing mass at least partially to the pretreated location, wherein the sealing mass is a silicone composition or a composition based on silane-terminated poly(meth)acrylates.
