ABSTRACT:
A method of making a solar cell has the following steps: (1) Formation of a surface layer including a dopant on a silicon substrate wherein the surface layer has a higher laser absorption index than the silicon substrate. (2) Irradiation by laser of the surface layer to form a junction in the silicon substrate.
