Abstract
A buried-contact solar cell, in-process buried-contact solar cell components and methods for making buried contact solar cells wherein a self-doping contact material is placed in a plurality of buried-contact surface grooves. By combining groove doping and metallization steps, the resulting solar cell is simpler and more economical to manufacture.
