<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a silicon single crystal substrate for a solar cell having a high recycling efficiency. <P>SOLUTION: A periphery of a silicon single crystal wafer W1 from which films other than a single crystal silicon have been removed is cut off at about right angles to a principal surface to obtain a rectangular silicon single crystal substrate W2, and then, the rectangular silicon single crystal substrate W2 is cut to a size corresponding to a substrate W4 for a solar cell into a plurality of silicon single crystal substrates W3, and the silicon single crystal substrates W3 are sliced parallel to the principal surface. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
