A method for metallization of solar cells is disclosed. The method includes providing a superstrate, such as a sheet of polymer film, to be used as a transport during metallization of solar cells. The method includes attaching the back sides of the solar cells to the sheet of polymer film. The method also includes forming contact holes through the sheet of polymer film to expose doped regions of the solar cells. The method also includes forming metals in the contact holes to electrically connect to the exposed doped regions of the solar cells. The method further includes electroplating the metals to form metal contacts of the solar cell. Subsequently, the method also includes separating the solar cells from other solar cells that were metallized while supported by the same sheet of polymer film to form strings of solar cells or individual solar cells. |
