摘要： The invention relates to a method for producing a metal contact structure of a photovoltaic solar cell, comprising the following method steps: applying an electrically non-conductive insulating layer to a surface of 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 a plurality of local regions, and the second paste containing metal particles is applied in a planar manner, covering at least the regions covered with the first paste as well as at least partially the regions located therebetween. As a result of a global heating of the semiconductor substrate the first paste penetrates the insulating layer and forms an electrically conductive contact directly with the semiconductor substrate, whereas the second paste does not penetrate the insulating layer and is electrically conductively connected to the semiconductor substrate only indirectly via the first paste.
