SOLAR CELL, SOLAR MODULE COMPRISING SAID SOLAR CELL AND METHOD FOR PRODUCING THE SAME AND FOR PRODUCING A CONTACT FOIL

摘要

The invention relates to a solar cell (1), which comprises the following layers: (a) a semi-conducting layer (2) comprising a first surface (4) and a second surface (5), wherein on the first surface (4) a plurality of first contact points (6) and second contact points (7) are formed, which have opposing polarities; (b) a first single- or multi-layered, perforated foil (8, 28) made of an electrically non-conductive material, which has a plurality of first holes (9); (c) a structured electrically conductive layer (10) on a surface of the perforated foil (8, 28) facing away from the semi-conducting layer (2); wherein the perforated foil (8, 28) and the semi-conducting layer (2) are positioned to each other such that at least part of the first holes (9) and of the first contact points (6) and of the second contact points (7) are located opposite of each other, wherein at least part of the first contact points (6) and of the second contact points (7) are connected by way of a solderless electrically conductive connection (11) to the structured electrically conductive layer (10). 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.
