  • Solar cell having dielectric back reflective coating and method for the production thereof
    Patent number: 9276155
    Abstract: In a method for producing a solar cell, a layer stack of dielectric layers is applied to a back of a solar cell substrate and the layer stack is heated and is held at temperatures of at least 700° C. during a time period of at least 5 minutes. The novel solar cell has a layer stack of dielectric layers on its back. At least one of the dielectric layers of the layer stack is densified so that its resistivity to firing-through of pastes with glass components is enhanced.
