1. A solar cell device comprising:

  • a silicon substrate including a preexisting dopant included therein;

    a homogeneous lightly doped region formed on a surface of the silicon substrate over the preexisting dopant, thereby forming a junction between the preexisting dopant and the lightly doped region;

    a heavily doped selectively implanted region on the surface of the silicon substrate within the lightly doped region;

    a seed layer formed over the heavily doped region; and

    a metal contact formed over the seed layer.
