The invention relates to a solar cell which comprises the following layers: (a) a semi-conducting layer comprising a first surface and a second surface, wherein on the first surface a plurality of first contact points and second contact points are formed, which have opposing polarities; (b) a first single- or multi-layered, perforated foil, made of an electrically non-conductive material, which has a plurality of first holes; and (c) a structured electrically conductive layer on a surface of the perforated foil facing away from the semi-conducting layer; wherein the perforated foil and the semi-conducting layer are positioned to each other such that at least a part of the first holes and of the first contact points and of the second contact points are located opposite of each other, wherein at least a part of the first contact points and of the second contact points are connected by way of a solderless electrically conductive connection to the structured electrically conductive layer. The invention further relates to a solar module which comprises a plurality of said solar cells, to a method for producing the solar cell, and to a method for producing a contact foil.
