Abstract
A method for producing a via in a III-V multijunction solar cell that comprises a substrate arranged on an underside. The substrate has an upper side and an epitaxial layer system with multiple III-V layers on the upper side, and the epitaxial layer system comprises at least one first III-V solar cell. An organic layer is arranged on the upper side of the first III-V solar cell, and an opening having a width X and a base surface formed in the epitaxial layer system is generated in a first method step with a laser. An opening having a width Y and having a base surface is generated in a second method step, width Y being smaller than width X, and an opening having a width Z is generated in a third method step, the opening not having a base surface, and width Z being smaller than width Y.
