When organic photovoltaic components are laser-structured, protuberances occur, which can protrude significantly beyond the height of the layered stack. The invention describes a technique for stabilising the laser-structured protuberances so that further processing of the semi-finished product is possible, and describes the integration of said product in a subsequent encapsulation of the OPV component.
