Abstract
An improved solar cell, and method for manufacture, in which a back side reverse p-n junction is formed prior to metallization and a gridded back side metallization material, chosen so that it penetrates the p-n junction where it is present, is fired into the wafer. The finished solar cell has improved efficiency despite the presence of the reverse p-n junction over a majority of the back face surface.
