Method for producing silicon solar cells having a front-sided texture and a smooth rear side surface

The invention relates to a method for producing a silicon solar cell which is smoothly etched on one side, in which a front and rear side of a silicon substrate are etched (10) to form a smooth texture, a dielectric coating is then applied onto the rear side of the silicon substrate (14, 16), and th...

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