  • Method for producing a metal contact structure of a photovoltaic solar cell
    Patent number: 8748310
    Abstract: A method for producing a metal contact structure of a photovoltaic solar cell, including: applying an electrically non-conductive insulating layer to a semiconductor substrate, applying a metal contact layer to the insulating layer, and generating a plurality of local electrically conductive connections between the semiconductor substrate and the contact layer right through the insulating layer. The metal contact layer is formed using two pastes containing metal particles: the first paste containing metal particles is applied to local regions, and the second paste containing metal particles is applied covering at least the regions covered with the first paste and partial regions located therebetween.
    Type: Grant
