Latest Patents

Wotke holds a patent for a method for producing a metal contact structure of a photovoltaic solar cell. This method involves applying an electrically non-conductive insulating layer to a semiconductor substrate, followed by the application of a metal contact layer. The process generates multiple local electrically conductive connections between the semiconductor substrate and the contact layer through the insulating layer. The metal contact layer is created using two pastes containing metal particles, with the first paste applied to specific regions and the second paste covering those regions and partial areas in between. By globally heating the semiconductor substrate, the first paste penetrates the insulating layer, forming an electrically conductive contact with the semiconductor substrate, while the second paste remains connected via the first paste.
