摘要： Method for producing a silicon solar cell which is smoothly etched on one side, in which a front side and a rear side of a silicon substrate are etched (10) to form a smooth texture, a dielectric coating is then formed (14, 16) on the rear side of the silicon substrate and the front side of the silicon substrate is subsequently textured (20) by means of a texture etching medium, the dielectric coating formed on the rear side of the silicon substrate being used as an etching mask against the texture etching medium.

摘要： A method for doping a semiconductor substrate includes heating the semiconductor substrate by irradiation with laser radiation and at the same time diffusing dopant from a dopant source into the semiconductor substrate in heated regions. The semiconductor substrate is heated by the irradiation with laser radiation. A surface portion of the semiconductor substrate that is less than 10% of the total surface of all irradiated regions is melted and recrystallized. There is also provided a solar cell.

摘要： 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.
