Abstract
A method of processing a solar cell is disclosed, where the edges of the solar cell are covered, coated or masked during the ion implantation process and/or the screen printing process. This covering may be a substance that blocks the penetration of ions during implantation, or may be a substance that resists the diffusion of fritted metal paste during the metallization process. In some embodiments, the edges are covered during both of these processes. In further embodiments, the same material may perform both functions.
