Abstract
The present invention relates to a method for producing solar wafers textured at least on one side, wherein in a first method step, sawn solar wafers with sawing damage are provided, and at the end of the last method step textured solar wafers with different size types of large and small pyramids are provided, and wherein the textured solar wafers can then be further processed to produce solar cells. The problem addressed by the present invention is that of providing an improved texturing method within the framework of the technology for the production of solar cells. This problem is solved by a method for producing textured solar wafers wherein in the first texture etching step the large pyramids are created in a low surface area density such that at the end of the method less than 30% of the textured surface of the solar wafer is occupied by the large pyramids; and in the second texture etching step the small pyramids are produced with a large surface area density.
