Method for the production of solar cells, comprising the production of a monograin membrane with the steps: providing a layer consisting of an electrically non-conductive binder on a carrier layer ; partially introducing of grains through a surface of the layer consisting of a binder into the layer ; wherein the grains consist of a material which is capable of converting sunlight into electrical energy; solidifying the electrically non-conductive binder into which the grains have been introduced, characterized in that the carrier film is unwound from a roll, a web which consists of alternating sections is continuously produced on the carrier layer , wherein a first section comprises the aforementioned layer with the electrically non-conductive binder together with grains protruding therefrom and a second web or strip-shaped electrically conductive section adjacent thereto comprises a layer or areas of electrically conductive material and these two sections alternate several times, the surface of the electrically non-conductive and electrically conductive sections thus produced is covered in sections in a web-like manner with a transparent, electrically conductive material in such a way that each web-like section is connected to only one electrically conductive section underneath; subsequently the carrier is removed and the surface thus exposed is covered with electrically conductive material in a web-like manner as well as in sections, in such a way that each web-like section is connected to only one electrically conductive section underneath, so that individual solar cells are electrically serially connected with each other. providing a layer consisting of an electrically non-conductive binder on a carrier layer ; partially introducing of grains through a surface of the layer consisting of a binder into the layer ; wherein the grains consist of a material which is capable of converting sunlight into electrical energy; solidifying the electrically non-conductive binder into which the grains have been introduced, characterized in that the carrier film is unwound from a roll, a web which consists of alternating sections is continuously produced on the carrier layer , wherein a first section comprises the aforementioned layer with the electrically non-conductive binder together with grains protruding therefrom and a second web or strip-shaped electrically conductive section adjacent thereto comprises a layer or areas of electrically conductive material and these two sections alternate several times, the surface of the electrically non-conductive and electrically conductive sections thus produced is covered in sections in a web-like manner with a transparent, electrically conductive material in such a way that each web-like section is connected to only one electrically conductive section underneath; subsequently the carrier is removed and the surface thus exposed is covered with electrically conductive material in a web-like manner as well as in sections, in such a way that each web-like section is connected to only one electrically conductive section underneath, so that individual solar cells are electrically serially connected with each other. <EOS>
