Abstract
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.
