NOVELTY - Roll to roll manufacturing low electrical resistivity conductive grids comprises providing a flexible continuous workpiece (105); applying an electrodeposition solution onto a plating region, and onto an anode; applying a voltage between the anode and the part of a first conductive film; selectively electrodepositing a conductive material onto the first film and not the transparent conductive layer to form a second conductive film, thus forming the low electrical resistivity conductive grids having reduced shading effect; and moving the front surface including part of the first film.    USE - Method of roll to roll manufacturing low electrical resistivity conductive grids having reduced shading effect for solar cells (claimed).    ADVANTAGE - The method can manufacture high electrical conductivity grid patterns having minimum shadowing effect on the illuminated side of the solar cells.    DETAILED DESCRIPTION - Roll to roll manufacturing low electrical resistivity conductive grids having reduced shading effect for solar cells comprises:    (A) providing a flexible continuous workpiece (105);    (B) applying an electrodeposition solution onto a plating region established on a portion of the front surface, including a part of the first conductive film, and onto an anode placed across from the portion of the front surface, where the plating region has a length that is the same as a width of the workpiece and a predetermined width that is at least longer than the predetermined spacing between adjacent grids;    (C) applying a voltage between the anode and the part of the first conductive film;    (D) selectively electrodepositing a conductive material from the electrodeposition solution onto the first conductive film and not the transparent conductive layer to form a second conductive film having a second resistivity atop the first conductive film, thus forming the low electrical resistivity conductive grids having reduced shading effect, where the first resistivity is greater than the second resistivity; and    (E) moving the front surface, including the part of the first conductive film, through the effective plating region, during the steps of applying the electrodeposition solution, applying the voltage, and selectively electrodepositing.    The workpiece comprises a continuous flexible substrate, a bottom contact layer, an absorber layer, a transparent conductive layer, and a first conductive film having a first resistivity disposed atop predetermined areas of a top surface of the transparent conductive layer and in electrical communication with the transparent conductive layer to form a raised grid pattern along a length of the flexible continuous workpiece. The raised grid pattern includes adjacent grids. Each grid has a predetermined grid width, a predetermined grid length, and a predetermined spacing between adjacent grids along the length direction of the workpiece. A sheet resistance of the first conductive film is less than the sheet resistance of the transparent conductive layer, and the top surface of the transparent conductive layer and the raised grid pattern form a front surface of the flexible continuous workpiece.
