Abstract (en)
[origin: DE19742653A1] The invention relates to a method for producing a wafer from a semiconducting material, especially a silicon wafer, for a solar cell. According to the inventive method, a melt of the semiconducting material (8) sets to form the wafer. The invention is characterised in that said melt is exposed to an electric and/or magnetic field at least during the start of the setting process.
