Abstract:
Method of making a current collecting grid for solar cells, including the steps of a) providing a continuous layer stack (1) on a substrate (8), the layer stack (1) including an upper (2) and a lower (3) conductive layer having a photoactive layer (4) interposed there between; b) selectively removing the upper conductive layer (2) and the photoactive layer (4) for obtaining a first contact hole (10) extending through the upper conductive layer (2) and photoactive layer (4) exposing the lower conductive layer (3); c) printing a front contact body (4) on the upper conductive layer (2) and a back contact body (5) in the first contact hole (10) on the lower conductive layer (3) and forming an electrically insulating first gap surrounding the back contact body (5) between the upper conductive layer (2) and the back contact body (2).
