Abstract
A method of manufacturing a solar cell. The method includes the steps of providing a substrate, applying a first dopant to a first surface, applying a second dopant to a second surface, covering the doped first surface with a hard mask, applying a third dopant to the substrate side, removing the hard mask, applying a pattern of first electrical contacts to the doping pattern, and applying a pattern of second electrical contacts to the doped second surface, the pattern of second electrical contacts and the doping pattern being straight-lined opposed.
