  • Patent number: 8324732
    Abstract: A semiconductor component, in particular in the form of a solar cell, comprises a two-dimensional semiconductor substrate with a first side, a second side which is arranged opposite thereto, a surface normal which is perpendicular to said first and second sides, and a plurality of recesses which are at least arranged on the second side and extend in the direction of the surface normal, at least one dielectric passivation layer which is arranged on the second side, an electrically conducting contact layer arranged on the passivation layer, a plurality of contact elements for electrically connecting the contact layer with the semiconductor substrate, which contact elements are electrically conductive, are in electrically conducting connection with both the semiconductor substrate and with the contact layer, fill at least 50%, in particular at least 90%, preferably 100% of in each case one of the recesses, project beyond the recesses with a projection in the direction perpendicular to the surface normal and are
