Abstract

In various embodiments, a method for producing a solar cell is provided. In accordance with the method, through-holes may be formed in a solar cell substrate having the basic doping of a first conduction type. Furthermore, predetermined surface regions of a first surface of the solar cell substrate which include at least one portion of the through-holes may be highly doped with a second, opposite conduction type; and simultaneously or subsequently other surface regions of the first surface are lightly doped with the second conduction type. Furthermore, first and second metallic contacts may subsequently be formed in such a way that the second metallic contacts are electrically isolated from the first metallic contacts.
